The Microtek SuperMAX+ 80KVA Dual Input Online UPS with Inbuilt Isolation Transformer (899-431-80TX) is a professional power backup solution designed for large commercial installations, institutional infrastructure, technical equipment rooms and compatible critical three-phase electrical systems.

Featuring 80KVA/80000W rated output capacity, a unity (1.0) output power factor, high-frequency true double-conversion technology, an inbuilt output isolation transformer and a 32 Amp inbuilt battery charger, the UPS combines substantial power capacity with advanced electrical protection.

Its three-phase input and three-phase output configuration, dual input provision, 5-inch touchscreen display and adjustable external battery system make the model suitable for professionally engineered power backup installations.

Manufactured by Microtek, the SuperMAX+ Series also supports manufacturer-approved parallel operation for organizations planning critical power infrastructure.

True Double-Conversion Online UPS Technology

The Microtek SuperMAX+ 80KVA Online UPS operates using true double-conversion technology.

During normal operation, incoming AC electricity passes through the UPS power conversion system before regulated output is delivered to connected equipment.

The inverter continuously supplies the protected load, helping reduce the impact of supported mains power disturbances and voltage variations.

When incoming mains electricity fails, a correctly configured external battery bank continues supplying power to the inverter.

Microtek specifies zero transfer time from normal online operation to battery mode.

This capability can be important for compatible computing systems, networking equipment and professional electronic installations where sudden interruptions could disrupt operations.

80KVA/80KW Rated Capacity with Unity Power Factor

The Microtek SuperMAX+ 80KVA ISO Transformer Online UPS delivers a rated apparent power capacity of 80000VA.

Its 1.0 unity output power factor provides a corresponding rated active-power capacity of 80000W under the manufacturer’s standard operating conditions.

This is an important distinction from UPS models with a lower output power factor.

The capacity makes the system relevant to larger professional electrical installations, provided the connected load is correctly sized.

Before selecting the UPS, customers should calculate continuous power requirements, peak operating loads, startup characteristics, phase distribution and suitable capacity headroom.

Microtek also specifies output-power derating at a special 360V AC output setting. The full 80KW rating should not be assumed to apply at every selectable output voltage.

Three-Phase Input and Three-Phase Output

The Microtek SuperMAX+ 80KVA Online UPS (899-431-80TX) supports three-phase input and three-phase output, commonly described as a 3:3 UPS configuration.

The manufacturer lists a nominal three-phase input supply of 400V AC with neutral.

Supported three-phase output settings include 360V, 380V, 400V and 415V AC.

This arrangement is intended for appropriately designed commercial and industrial electrical infrastructure that requires regulated three-phase power.

The electrical installation must account for phase sequence, neutral requirements, protective earthing, distribution equipment and load characteristics.

A qualified electrical professional should verify compatibility before commissioning.

Inbuilt Output Isolation Transformer

One of the most important features of the Microtek SuperMAX+ 80KVA Online UPS is its inbuilt output isolation transformer.

The isolation transformer provides galvanic separation within the supported output electrical arrangement.

This can help reduce certain common-mode electrical disturbances and provide electrical isolation where required by the installation design.

Unlike transformerless SuperMAX+ variants, the 80TX model integrates the isolation transformer into its cabinet.

This makes the model an option for projects where output isolation is an important procurement requirement.

However, an isolation transformer does not replace the need for correct grounding, circuit protection, surge protection or safe operating procedures.

Applications involving specialized machinery or regulated equipment must be evaluated against their specific electrical requirements.

Dual Input Electrical Arrangement

The Microtek SuperMAX+ 80KVA Dual Input Online UPS provides a dual AC input configuration.

Microtek’s technical literature describes this feature as allowing an approved secondary electrical source on the bypass input or a suitable Hot Standby-related arrangement.

Dual input can support flexible power infrastructure planning where more than one suitable incoming AC supply path is available.

However, dual input does not automatically increase the output capacity of the UPS.

The rectifier input, bypass input, source synchronization and electrical protection must be configured according to Microtek’s approved installation procedures.

Advanced DSP-Controlled Three-Level Inverter

The Microtek SuperMAX+ 80KVA Online UPS incorporates advanced Digital Signal Processing technology.

The three-level inverter architecture helps manage electrical power conversion and operating performance.

Digital control supports output regulation, battery management and monitoring of important UPS conditions.

Microtek also specifies active input power factor correction across the three input phases.

The manufacturer’s technical brochure lists an input power factor of at least 0.99 at full load.

This input-side characteristic is separate from the UPS’s unity output power factor.

Flexible 32–40 Battery System

The Microtek SuperMAX+ 80KVA Online UPS uses an external high-voltage battery system.

The supported technical range is 32 to 40 compatible 12V batteries.

The battery configuration uses a centre-tapped arrangement, with two nominally equal DC battery sections.

A 32-battery arrangement provides approximately ±192V DC, while a 40-battery arrangement provides approximately ±240V DC.

The total nominal voltage between the positive and negative DC rails is approximately 384V to 480V, depending on the approved configuration.

Correct positive, negative and midpoint connections are essential.

The battery bank must be wired according to the manufacturer-approved installation diagram.

Recommended Minimum 40 × 100Ah Battery Setup

The commercial description for SKU 899-431-80TX specifies a recommended minimum arrangement of 40 compatible batteries rated at 100Ah each, subject to actual load requirements.

This is an important consideration for customers purchasing a high-capacity 80KVA power backup system.

Although the UPS supports an adjustable battery count, lower battery quantities should not be selected simply because the technical range permits them.

The final battery design must consider connected load, required backup time, discharge current, battery specifications and operating conditions.

A professional battery-sizing calculation should be completed before ordering.

External batteries, battery racks, DC protection devices and interconnecting cables form part of the overall power backup installation.

32 Amp Inbuilt Battery Charger

The Microtek SuperMAX+ 80KVA ISO Transformer Online UPS features a 32 Amp maximum inbuilt battery charger.

The manufacturer’s technical brochure describes an adjustable charging-current range from 2A to 32A.

This provides flexibility when configuring a compatible external battery bank.

The charging current should be selected according to battery capacity, charging characteristics and manufacturer recommendations.

The maximum charging-current setting is not automatically suitable for every battery installation.

Correct configuration helps maintain battery readiness and supports reliable long-term operation.

Pure Sine Wave Output

The Microtek SuperMAX+ 80KVA Online UPS delivers pure sine wave output during battery operation.

Pure sine wave power is suitable for many compatible electronic power supplies and professional electrical systems.

The manufacturer specifies approximately ±1% output voltage regulation during battery mode.

For the isolation-transformer 80KL design, Microtek lists output harmonic distortion of 2% or less for linear loads and 10% or less for non-linear loads.

The published current crest ratio is approximately 2.6:1 maximum.

These values should not be interchanged with the different electrical specifications of transformerless SuperMAX+ models.

5-Inch Touchscreen LCD Display

The Microtek SuperMAX+ 80KVA Dual Input Online UPS features a modern 5-inch touch panel LCD.

The touchscreen provides information about UPS status, connected load, output current on individual phases and output power.

It also displays battery charging and discharging information, input and output voltages, frequency, operating temperature and fault events.

Microtek lists support for a data log containing up to 500 events.

This monitoring functionality can help electrical maintenance teams and facility managers supervise the UPS’s operating condition.

The display also supports approved monitoring and configuration functions.

Parallel Redundancy with Up to Four UPS Units

The Microtek 80KVA SuperMAX+ Online UPS (899-431-80TX) supports parallel operation with up to four compatible UPS units.

This feature can be useful for organizations designing redundant critical power systems.

Microtek describes manufacturer-approved parallel configurations using either individual battery banks for each UPS or a common battery bank.

However, parallel connection requires compatible equipment, electrical synchronization and correctly designed protection.

Parallel and current-sharing cables are optional accessories that must be ordered separately.

The actual system capacity and redundancy level depend on the selected architecture.

Multiple UPS units must never be connected in parallel without manufacturer-approved commissioning.

Common or Separate Battery Bank Options

The SuperMAX+ 80KVA UPS supports different approved battery arrangements in parallel installations.

A common battery bank allows compatible UPS units to share a suitably engineered external battery system.

A separate battery-bank arrangement provides dedicated battery support to individual UPS units.

These configurations have different electrical wiring, battery sizing, isolation and protection requirements.

The correct design should be selected with Microtek’s technical approval.

ECO Mode and Operating Efficiency

The Microtek SuperMAX+ 80KVA isolation-transformer UPS supports ECO operating mode.

The manufacturer specifies approximately 87.5% efficiency in AC mode, 93.5% in ECO mode and 86.5% in battery mode for its 80KL isolation-transformer configuration.

These figures are different from the efficiency ratings of the lighter transformerless SuperMAX+ range.

The inbuilt isolation transformer provides electrical isolation but also contributes to increased weight and conversion losses.

ECO mode can improve efficiency when the incoming electricity meets the supported conditions.

However, the operating mode should be selected according to the required continuity and power-quality characteristics.

Output Capacity at 360V AC

Microtek specifies a 90% output-power derating when the three-phase output is configured at 3 × 360V AC.

For an 80KW standard rated system, this corresponds to approximately 72KW under that setting.

This must not be confused with the UPS’s DC battery voltage.

The 360V AC output setting refers to the three-phase output supply, while the external battery system is described using split-voltage DC ratings such as ±192V and ±240V.

Built-In Maintenance Bypass and Emergency Power Off

The Microtek SuperMAX+ Series supports maintenance bypass operation and an Emergency Power Off function.

Maintenance bypass supports designated service procedures under approved operating conditions.

Emergency Power Off can be integrated into a suitable electrical safety arrangement.

However, bypass operation may expose connected equipment to the electrical characteristics of the bypass supply.

All maintenance and switching procedures must be performed by qualified personnel according to Microtek’s instructions.

Generator Compatibility

The Microtek SuperMAX+ 80KVA Online UPS supports suitable standby generator supplies.

This allows a properly engineered generator to act as an additional source of electricity during extended mains failures.

Generator sizing should consider connected electrical loads, UPS power conversion characteristics, battery charging demand and suitable operating margins.

The generator must provide voltage and frequency within the UPS’s approved input limits.

Communication and Remote Monitoring

The UPS provides RS232 and USB communication interfaces for supported monitoring applications.

Optional SNMP network management allows compatible remote monitoring through appropriate software or a web browser.

These features can help technical personnel monitor system conditions and manage critical power installations.

The required communication accessories should be included in the quotation where necessary.

Optional Backfeed Energy Absorption Box

Microtek lists an optional external backfeed energy absorption box for certain regenerative-load applications.

Selected elevators, lifts and CNC machines can return electrical energy toward a connected power source under particular conditions.

This energy may cause a UPS internal DC-bus overvoltage fault if it is not properly managed.

A correctly sized and approved energy absorption accessory may be useful for compatible applications.

However, this accessory does not automatically make every regenerative machine suitable for connection to the UPS.

The complete electrical system must be reviewed by Microtek and the machinery manufacturer before installation.

Heavy-Duty Floor-Standing Cabinet

The Microtek SuperMAX+ 80KVA Online UPS with Inbuilt Isolation Transformer uses a substantial industrial floor-standing cabinet.

The manufacturer’s 80KL isolation-transformer datasheet specifies dimensions of approximately 790 × 720 × 1060 mm and a net UPS weight of 475kg, excluding external batteries.

This is significantly heavier than the corresponding transformerless 80KVA design.

The installation site must provide suitable floor-loading capacity, transportation access, ventilation and maintenance clearances.

The external battery system requires additional protected installation space.

Accessories Not Included with the UPS

According to the commercial description for SKU 899-431-80TX, the following accessories are not included:

• Battery links
