Microtek SuperMAX+ 100KVA Dual Input 3-Phase Online UPS

Microtek SuperMAX+ 100KVA Dual Input Online UPS – Advanced 100KW Three-Phase Power Backup

The Microtek SuperMAX+ 100KVA Dual Input Online UPS (899-431-1003) is a high-performance, high-frequency uninterruptible power supply designed for large commercial infrastructure, data centres, institutional facilities and compatible critical three-phase electrical equipment.

Featuring 100KVA/100000W rated output capacity, a unity (1.0) output power factor, true double-conversion technology, a 24 Amp inbuilt battery charger and a modern 7-inch touchscreen LCD, this Microtek SuperMAX+ model delivers regulated pure sine wave power for demanding professional installations.

The UPS supports three-phase input and three-phase output (3:3), dual AC input functionality and an adjustable external battery system using 32 to 40 compatible 12V batteries.

Manufactured by Microtek, the SuperMAX+ Series also supports approved parallel redundancy arrangements with up to four compatible UPS units.

Advanced True Double-Conversion Online UPS Technology

The Microtek SuperMAX+ 100KVA Online UPS uses true double-conversion technology.

During normal operation, incoming AC electricity is processed through the UPS rectifier and inverter before regulated output power is supplied to the connected equipment.

This design helps protect compatible electronic equipment against supported power disturbances, voltage fluctuations and unexpected mains failures.

When the mains electricity becomes unavailable, the external battery bank continues supplying energy to the inverter.

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

This is especially relevant to critical computing infrastructure and other professional equipment where sudden power interruptions may disrupt operations.

100KVA/100KW Output Capacity with Unity Power Factor

The Microtek SuperMAX+ 100KVA Online UPS has a rated apparent power capacity of 100000VA and an active power capacity of 100000W.

Its 1.0 output power factor allows the rated active power to equal the apparent power under standard manufacturer conditions.

This provides a higher rated wattage than a conventional 100KVA UPS with a 0.9 output power factor, which would be rated at 90000W.

The 100KW capacity makes this UPS relevant to properly sized large-scale IT installations and compatible commercial electronic equipment.

Before selecting a 100KVA UPS, the total electrical load should be evaluated carefully.

The calculation must consider continuous power consumption, startup currents, phase distribution, operating peaks and appropriate capacity headroom.

At the manufacturer’s special 3 × 360V AC output setting, the UPS is subject to 90% derating, reducing the available rated active power to approximately 90KW.

Three-Phase Input and Three-Phase Output

The Microtek SuperMAX+ 100KVA Dual Input Online UPS operates with three-phase input and three-phase output, also known as a 3:3 UPS configuration.

Microtek specifies nominal three-phase input at 400V AC, with neutral.

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

This configuration is intended for professional electrical installations that require regulated three-phase power.

Electrical compatibility must be checked before installation, particularly where connected equipment has unusual starting currents or specialized power requirements.

Correct phase sequence, neutral distribution, protective earthing and circuit protection are essential.

High-Frequency Transformerless Design

The Microtek SuperMAX+ 100KVA Online UPS uses a high-frequency transformerless architecture.

This design supports efficient electrical conversion without an integrated output isolation transformer.

The transformerless configuration distinguishes this model from Microtek’s separate isolation-transformer UPS products.

Where galvanic output isolation is required, an appropriately specified external transformer or another approved UPS configuration should be considered.

The transformerless design does not eliminate the need for grounding, surge protection or appropriate electrical safety measures.

DSP-Controlled Three-Level Inverter Technology

The Microtek SuperMAX+ Series incorporates Digital Signal Processing (DSP) technology and a three-level inverter design.

DSP-based control manages power conversion, monitoring and output regulation.

The manufacturer identifies active input power factor correction across all three phases.

Its technical brochure specifies an input power factor of at least 0.99 at full load.

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

The advanced inverter design helps minimize certain conversion losses and supports efficient operation.

Dual Input Power Configuration

The Microtek SuperMAX+ 100KVA Dual Input Online UPS provides dual AC input capability.

According to Microtek, the design supports a separate secondary AC source connected through the approved bypass arrangement or certain Hot Standby configurations.

This flexibility may be useful for organizations planning additional power-source availability.

However, the dual-input feature should not be treated as unrestricted source switching or an increase in UPS output capacity.

Rectifier input, bypass input, electrical protection and source synchronization must be engineered according to the manufacturer’s instructions.

External 32–40 Battery System

The UPS supports a configurable external battery system using 32 to 40 compatible 12V batteries.

Microtek’s technical documentation describes a centre-tapped battery arrangement with separate positive and negative sections.

The standard 32-battery configuration corresponds to approximately ±192V DC.

At 40 batteries, the nominal battery voltage is approximately ±240V DC.

The complete nominal voltage across the positive and negative rails therefore ranges from approximately 384V to 480V.

Approved battery quantities include 32, 34, 36, 38 and 40 batteries.

Battery polarity, midpoint connections, charging configuration and DC protection must be installed according to the manufacturer-approved wiring diagram.

Recommended Minimum 40 × 150Ah Batteries

For SKU 899-431-1003, Microtek’s February 2026 commercial description recommends a minimum of forty compatible batteries rated at 150Ah each, subject to the connected load.

This is particularly important for high-capacity commercial installations.

Although the technical battery quantity is adjustable from 32 to 40, every battery-count option is not necessarily suitable for every electrical load.

The final battery bank must be sized according to actual power consumption, required backup duration, discharge current, battery condition and operating temperature.

Backup time cannot be accurately determined from the 100KVA rating alone.

External batteries, battery racks, interconnecting cables and protective devices should be included in the complete system quotation.

Powerful 24 Amp Inbuilt Battery Charger

The Microtek SuperMAX+ 100KVA Online UPS features a 24A maximum inbuilt battery charger.

Microtek specifies adjustable charging current from 2A to 24A for the 100KL model.

The charger supports a manufacturer-described three-stage charging design intended to optimize battery performance.

The appropriate charging current depends on the battery capacity and approved charging characteristics.

The maximum charger rating should not automatically be selected for every battery system.

Charging settings must be established by qualified personnel according to the battery manufacturer’s instructions.

Pure Sine Wave Output

The Microtek SuperMAX+ 100KVA UPS provides pure sine wave output during battery operation.

Pure sine wave electricity is suitable for many properly matched computing systems and professional electronic power supplies.

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

Output harmonic distortion is rated at 2% or less for linear loads and 5% or less for non-linear loads.

These specifications help support stable electrical output within the supported operating conditions.

Advanced 7-Inch Touchscreen LCD Display

One of the key features of the Microtek SuperMAX+ 100KVA Online UPS is its 7-inch touchscreen LCD.

The display provides real-time access to important electrical and operating information.

It can show UPS status, connected load percentages, per-phase output current, output VA, output wattage and battery charging or discharging current.

The touchscreen also provides input and output voltage information, input and output frequency, operating temperature and fault indications.

Microtek specifies an event logging capacity of up to 500 events.

This monitoring interface helps electrical maintenance teams and facility managers supervise large power backup installations.

Swappable Power Modules for Easier Maintenance

The manufacturer’s brochure describes the 100KVA SuperMAX+ model as having two 50KW swappable power modules with common control boards.

This modular design is intended to simplify certain service and maintenance procedures.

It should not be interpreted as permission to remove or replace power modules while the UPS is operating unless Microtek’s approved service instructions expressly permit it.

Authorized technical personnel should perform all servicing.

The arrangement helps distinguish the 100KVA model from smaller SuperMAX+ capacities.

ECO Mode and High Operating Efficiency

The Microtek SuperMAX+ 100KVA UPS supports ECO mode.

The manufacturer lists peak efficiencies of approximately:

• 95.5% in AC mode
• 98.5% in ECO mode
• 94.5% in battery mode

High conversion efficiency can help reduce electrical losses and operating heat.

However, ECO mode differs from normal continuous double-conversion operation.

The correct operating mode should be selected according to the connected equipment’s power-quality and continuity requirements.

Parallel Redundancy with Up to Four Units

The Microtek SuperMAX+ 100KVA Online UPS supports manufacturer-approved parallel operation with up to four compatible UPS units.

This capability can be used when designing suitable redundant or higher-capacity critical-power systems.

Microtek describes supported arrangements with either a common battery bank or separate battery banks for individual UPS units.

However, the maximum usable output and redundancy level depend on the selected configuration.

Parallel communication cables, current-sharing cables, synchronization and appropriate protective devices are required.

These accessories must be specified according to the manufacturer’s approved design.

Common or Separate Battery Bank Options

Parallel SuperMAX+ installations may use an approved common external battery bank or individual battery banks.

A common bank must be engineered for the complete connected UPS system.

Separate banks provide dedicated battery support to individual units.

These arrangements have different wiring, protection and operating requirements.

The correct configuration should be confirmed with Microtek during project planning.

Maintenance Bypass and Emergency Power Off

The Microtek SuperMAX+ Series provides maintenance bypass functionality and an Emergency Power Off (EPO) feature.

Maintenance bypass supports approved servicing procedures.

The EPO function can be incorporated into an appropriately designed electrical safety system.

However, bypass operation may expose connected equipment to the bypass source.

All related switching and maintenance activities must follow the manufacturer’s procedures.

Generator Compatibility

The Microtek SuperMAX+ 100KVA Dual Input Online UPS supports operation with suitable standby generators.

This can be useful for facilities with extended backup power requirements.

Generator sizing should account for the full connected load, battery charging demand, input power factor and electrical characteristics.

The generator must provide acceptable input voltage and frequency for the UPS.

Optional Backfeed Energy Absorption Box

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

Examples can include selected elevators, lifts and CNC machines.

Regenerative loads may return electrical energy toward the UPS output during particular operating conditions.

A correctly specified absorption accessory may be required to manage this returned energy.

Compatibility must be verified for the exact machinery and UPS installation.

The optional accessory does not automatically make all regenerative loads suitable.

Communication and Network Monitoring

The Microtek SuperMAX+ 100KVA Online UPS supports RS232 and USB communication.
