Microtek SuperMAX+ 120KVA Dual Input Online UPS – High-Performance 120KW Power Backup Solution

The Microtek SuperMAX+ 120KVA Dual Input Online UPS (899-431-1203) is an advanced high-frequency uninterruptible power supply designed for large commercial infrastructure, data centres, institutional facilities and compatible critical three-phase electrical equipment.

Featuring 120KVA/120000W rated output capacity, a unity (1.0) output power factor, true double-conversion technology, a 36 Amp inbuilt charger and a modern 7-inch touchscreen LCD, this Microtek SuperMAX+ UPS provides regulated power for demanding professional environments.

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

Manufactured by Microtek, the SuperMAX+ Series also supports manufacturer-approved parallel operation for organizations designing higher-capacity or redundant critical power infrastructure.

True Double-Conversion Online UPS Technology

The Microtek SuperMAX+ 120KVA Online UPS uses true double-conversion technology to deliver continuous inverter-based power.

During normal operation, incoming AC electricity is processed through the UPS conversion system before being supplied to connected equipment.

This arrangement helps reduce the impact of supported mains power disturbances, voltage fluctuations and unexpected interruptions.

When 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 capability is valuable for compatible electronic equipment that must continue operating during brief or extended mains failures.

120KVA/120KW Rated Capacity with Unity Power Factor

The Microtek SuperMAX+ 120KVA Online UPS provides a rated apparent power capacity of 120000VA and an active power rating of 120000W.

Its 1.0 unity output power factor allows the active-power rating to equal the apparent-power capacity under the manufacturer’s standard rated operating conditions.

Compared with a 120KVA UPS rated at 0.9 power factor, which provides 108000W, the unity power factor offers greater rated active-power capacity.

This makes the SuperMAX+ 120KVA suitable for evaluation in larger electrical infrastructure projects.

Customers should calculate the connected equipment’s total operating load before choosing the UPS.

This calculation should include continuous wattage, starting currents, load distribution, operating peaks and suitable capacity headroom.

Three-Phase Input and Three-Phase Output

The Microtek SuperMAX+ 120KVA Dual Input Online UPS features three-phase input and three-phase output, commonly described as a 3:3 UPS.

The manufacturer specifies nominal three-phase input voltage of 3 × 400V AC, with neutral.

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

This configuration is suitable for professionally engineered installations requiring regulated three-phase electricity.

Phase sequence, neutral distribution, protective earthing and electrical connection sizes should be checked before commissioning.

The manufacturer specifies that the special 3 × 360V AC output setting requires a reduction in available output capacity.

120KW Output and 360V Derating

Under standard manufacturer-rated conditions, the Microtek SuperMAX+ 120KVA UPS provides 120KW of active output power.

However, Microtek specifies 90% power derating when the output is configured to 3 × 360V AC.

At this voltage setting, the available rated active output becomes approximately 108KW.

This is an AC output-voltage limitation and is separate from the UPS’s external DC battery voltage.

Customers must confirm the required output voltage before finalizing UPS capacity calculations.

High-Frequency Transformerless Design

The Microtek SuperMAX+ 120KVA Online UPS uses a high-frequency transformerless architecture.

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

The transformerless arrangement contributes to the UPS’s manufacturer-listed conversion efficiency and cabinet characteristics.

Where galvanic output isolation is required, an appropriately designed external isolation transformer or a different approved UPS arrangement should be specified.

The absence of an inbuilt isolation transformer does not reduce the need for correct grounding, protection devices or professional installation.

DSP-Controlled Three-Level Inverter Technology

The Microtek SuperMAX+ 120KVA UPS incorporates Digital Signal Processing technology with a three-level inverter design.

DSP control supports regulated power conversion, electrical monitoring and UPS operating management.

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

The manufacturer lists an input power factor of at least 0.99 at full load.

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

The inverter architecture is designed to support high-efficiency operation under appropriate electrical conditions.

Dual AC Input Design

The Microtek SuperMAX+ 120KVA Dual Input Online UPS includes dual AC input provision.

Microtek describes the design as supporting approved arrangements involving a secondary source connected to the bypass input or compatible Hot Standby-related installations.

This provides flexibility in professionally engineered critical power systems.

However, dual input does not automatically increase the UPS’s rated output capacity.

Rectifier input, bypass input, electrical protection and source synchronization must be configured according to Microtek’s approved instructions.

Flexible 32–40 External Battery System

The Microtek SuperMAX+ 120KVA UPS supports 32 to 40 compatible external 12V batteries.

The manufacturer’s technical literature describes a centre-tapped split-battery arrangement.

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

A 40-battery configuration corresponds to approximately ±240V DC.

The complete nominal voltage between the positive and negative battery terminals therefore ranges from approximately 384V to 480V.

Supported battery quantities include 32, 34, 36, 38 and 40 batteries, subject to the approved configuration.

Battery connections must follow the manufacturer’s positive, negative and midpoint wiring requirements.

Because this is a hazardous high-voltage DC system, installation must be performed by qualified personnel.

Recommended Minimum 40 × 150Ah Battery Configuration

The commercial specification of Microtek SKU 899-431-1203 recommends a minimum of 40 compatible external batteries rated at 150Ah each, subject to the connected load.

This recommendation is important for customers planning a complete 120KVA power backup system.

Although the UPS technically supports a wider adjustable battery range, a lower battery quantity or ampere-hour rating is not automatically suitable for every installation.

Backup duration depends on connected load, battery capacity, discharge characteristics, environmental temperature, battery condition and UPS efficiency.

Professional battery sizing is necessary to determine the required backup time.

External batteries, racks, interconnecting cables and DC protection equipment must be included in the overall system design.

Powerful 36 Amp Inbuilt Charger

The Microtek SuperMAX+ 120KVA Online UPS features a 36 Amp maximum inbuilt battery charger.

The manufacturer specifies adjustable charging current from 2A to 36A for the 120KL model.

This allows the charger to be configured according to the approved external battery arrangement.

Microtek also describes a three-stage charging design intended to support battery performance.

The highest charger-current setting is not necessarily appropriate for every battery bank.

Charging parameters should be selected according to the battery capacity and manufacturer recommendations.

Pure Sine Wave Output and Voltage Regulation

The Microtek SuperMAX+ 120KVA UPS delivers pure sine wave output during battery operation.

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

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

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

The UPS also supports a maximum current crest ratio of approximately 3:1 under its published specifications.

These characteristics help maintain regulated electrical output within the approved operating range.

Advanced 7-Inch Touchscreen LCD Display

One of the most distinctive features of the Microtek SuperMAX+ 120KVA Online UPS is its 7-inch touchscreen LCD.

The display provides access to UPS status, connected load percentage, output current across individual phases and electrical power measurements.

It also displays battery charging and discharging current, input and output voltage, frequency, temperature, operating alerts and fault conditions.

Microtek identifies an event log capable of storing up to 500 events.

This monitoring functionality helps technical personnel supervise critical power infrastructure.

The larger touchscreen is particularly useful for viewing detailed electrical measurements during operation and maintenance.

Two 60KW Swappable Power Modules

Microtek describes the 120KVA SuperMAX+ model as incorporating two 60KW swappable power modules with common control boards.

This design is intended to simplify certain servicing and maintenance activities.

The modules form part of the manufacturer’s supported power architecture.

However, module replacement must be performed according to Microtek’s authorized servicing instructions.

The term swappable should not automatically be interpreted as permission for live replacement while the UPS is operating.

ECO Mode and High Operating Efficiency

The Microtek SuperMAX+ 120KVA UPS supports ECO mode to reduce power conversion losses when incoming electrical conditions are suitable.

The manufacturer specifies peak efficiencies of approximately 95.5% in AC mode, 98.5% in ECO mode and 94.5% in battery mode.

These figures describe the published manufacturer test conditions.

ECO mode differs from normal continuous double-conversion operation and may affect transfer behaviour.

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

Parallel Operation with Up to Four Compatible UPS Units

The official Microtek SuperMAX+ 60–120KVA technical brochure specifies parallel capability with up to four compatible UPS units.

For the 120KVA model, this allows appropriately engineered redundant or higher-capacity power backup architectures.

The manufacturer describes approved parallel arrangements using either a common battery bank or separate battery banks for individual UPS units.

Actual usable power and redundancy depend on the selected architecture.

Parallel operation requires compatible UPS hardware, synchronization, current-sharing communication and properly rated protection equipment.

Microtek identifies parallel and current-sharing cables as optional accessories that must be ordered separately.

Although the 120KVA SKU’s commercial description does not explicitly repeat the parallel capability, it is documented in the manufacturer series brochure and should be confirmed for the supplied revision before procurement.

Maintenance Bypass and Emergency Power Off

The Microtek SuperMAX+ Series provides maintenance bypass functionality.

This supports manufacturer-approved servicing procedures under suitable operating conditions.

The UPS also includes an Emergency Power Off feature for integration into properly designed electrical safety arrangements.

During bypass operation, connected equipment may receive electricity directly from the bypass supply.

All electrical switching, servicing and EPO connections must follow Microtek’s approved procedures.

Generator Compatibility

The Microtek SuperMAX+ 120KVA Online UPS is compatible with appropriately selected generator supplies.

This makes the system relevant to facilities with standby power generation.

Generator sizing should consider the connected electrical load, battery charging requirements and UPS input characteristics.

A suitable generator must supply voltage and frequency within the UPS’s approved operating range.

Communication and Remote Monitoring

The UPS supports RS232 and USB communication for compatible monitoring applications.

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

The larger SuperMAX+ technical brochure also lists a dry-contact communication interface with eight inputs and six outputs.

These features can assist data centre personnel, electrical teams and facility managers with UPS supervision.

The required monitoring hardware and software should be confirmed in the purchase quotation.

Optional Backfeed Energy Absorption Box

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

Selected elevators, lifts and CNC machines can return electrical energy toward the power source during specific operating conditions.

If this returned energy is not properly managed, it may cause UPS protection faults.

A correctly specified absorption accessory may be required for supported applications.

However, equipment compatibility must be confirmed with Microtek before installation.

The optional accessory is not part of the standard UPS supply.

Accessories Not Included with the UPS

The commercial description for SKU 899-431-1203 explicitly excludes:

• Battery links
