Microtek 40KVA SuperMAX+ Online UPS – High-Frequency 3-Phase Power Backup Solution

The Microtek 40KVA/±192V SuperMAX+ 3-Phase Online UPS (899-430-4002) is a high-capacity power backup system designed for commercial IT infrastructure, institutional facilities, professional computing environments and compatible critical three-phase electronic equipment.

Featuring 40KVA/40000W rated output, a unity (1.0) output power factor, high-frequency true double-conversion technology and a 12A inbuilt battery charger, this Microtek SuperMAX+ model delivers dependable pure sine wave power for demanding installations.

The UPS features three-phase input and three-phase output (3:3) and operates with an external battery system supporting 32 to 40 compatible 12V batteries.

Developed by Microtek, this power backup solution combines DSP-controlled IGBT technology, a 4.3-inch touchscreen, intelligent battery charging and manufacturer-approved parallel operation.

True Double-Conversion Online UPS Technology

The Microtek SuperMAX+ 40KVA Online UPS uses true double-conversion technology to supply regulated electrical power.

During normal operation, incoming electricity is processed through the UPS power conversion system before the inverter supplies power to connected equipment.

This arrangement helps reduce the effects of many incoming electrical disturbances, including voltage fluctuations and unexpected power failures.

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

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

This supports continuity for compatible computing infrastructure, network equipment and other professional electronics where sudden power interruptions may disrupt operations.

40KVA/40000W Capacity with Unity Power Factor

The Microtek SuperMAX+ 40KVA Online UPS provides a manufacturer-rated capacity of 40000VA/40000W.

Its unity output power factor means the rated active power is equal to the rated apparent power under the manufacturer’s specified operating conditions.

A 40KVA UPS with a 0.8 output power factor provides 32000W of rated active output, whereas this model delivers 40000W under standard rated conditions.

This makes the SuperMAX+ model relevant to larger commercial and technical installations.

However, connected equipment must be sized according to actual continuous power requirements, startup current, operating peaks and available capacity headroom.

Microtek specifies that output capacity is reduced to 90% when operating at the 3 × 360V AC output setting. At that setting, the corresponding rated active power becomes 36000W.

Three-Phase Input and Three-Phase Output

The Microtek 40KVA/±192V SuperMAX+ Online UPS supports three-phase input and three-phase output, commonly referred to as a 3:3 UPS.

Its nominal electrical input is specified as 3 × 400V AC with neutral.

The manufacturer lists supported three-phase output voltage settings of 360V, 380V, 400V and 415V AC.

This configuration makes the UPS suitable for properly designed facilities requiring regulated three-phase power.

It should not be confused with Microtek’s configurable Dual Input models, which may support additional phase arrangements.

Before commissioning, the phase sequence, neutral arrangement, grounding, cable sizes and protective devices must be verified by qualified personnel.

Advanced DSP-Controlled Three-Level IGBT Technology

The Microtek SuperMAX+ 40KVA Online UPS incorporates Digital Signal Processing technology and a three-level IGBT inverter.

This system supports efficient electrical power conversion and stable operating characteristics.

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

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

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

Together, the digital control system and IGBT-based power conversion technology support efficient operation in suitable commercial electrical environments.

Flexible ±192V to ±240V DC Battery System

The Microtek SuperMAX+ 40KVA Online UPS uses a centre-tapped external battery bank.

The default battery configuration requires 32 compatible 12V batteries, arranged as two equal nominal 192V sections.

This configuration is identified as ±192V DC.

The full nominal voltage between the positive and negative DC rails is approximately 384V.

The supported battery configuration can be extended to 40 batteries, corresponding to a split voltage of ±240V DC and a full nominal rail-to-rail voltage of 480V.

The battery midpoint, polarity and protection must be connected exactly according to Microtek’s approved wiring diagram.

Improper battery connections can create serious electrical hazards and damage the UPS.

Adjustable 32 to 40 Battery Configuration

The manufacturer specifies adjustable battery quantities in pairs of two.

The supported options are 32, 34, 36, 38 and 40 external batteries.

This flexibility allows suitable battery voltage configurations within the approved operating range.

However, the number of batteries alone does not determine the backup duration.

Runtime also depends on battery ampere-hour capacity, connected load, battery condition, discharge characteristics and UPS efficiency.

The battery system should be sized according to the customer’s required backup period.

Compatible VRLA or lead-acid batteries can be considered in accordance with the manufacturer’s technical recommendations.

12 Amp Inbuilt Battery Charger

The Microtek SuperMAX+ 40KVA Online UPS includes a 12A maximum inbuilt battery charger.

Microtek specifies adjustable charging current from 1A to 12A, in 1A increments.

The documented factory-default setting is 4A.

This allows a compatible charging current to be selected for the installed battery bank.

The maximum available charger current is not automatically appropriate for every battery size.

Charging configuration should be based on battery capacity, charging limits and the manufacturer’s instructions.

The UPS also features a three-stage charging design intended to optimize battery charging performance.

Pure Sine Wave Output and Voltage Regulation

The Microtek SuperMAX+ 40KVA UPS delivers pure sine wave output during battery operation.

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

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

The manufacturer also lists output harmonic distortion of 2% or less for linear loads and 5% or less for non-linear loads.

These characteristics help maintain stable electrical output within the approved operating limits.

Smart 4.3-Inch Touch Panel LCD

A key feature of the Microtek SuperMAX+ 40KVA Online UPS is its 4.3-inch touch panel LCD.

The display provides access to system operating information and supported settings.

Microtek identifies information such as UPS status, connected load percentage, output current on each phase, output wattage and output volt-amperes.

The interface also provides battery charge and discharge information, input and output voltages, frequency, temperature and event logs.

This is useful for electrical maintenance teams, facility managers and IT administrators responsible for monitoring critical equipment.

ECO Mode and High Operating Efficiency

The Microtek SuperMAX+ Series supports ECO mode.

The manufacturer specifies operating efficiencies of approximately 95.5% in AC mode, 98.5% in ECO mode and 94.5% in battery mode under its published test conditions.

Improved efficiency can reduce power conversion losses and heat generation.

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

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

Parallel Redundancy with Up to Four UPS Units

The Microtek 40KVA/±192V SuperMAX+ Online UPS (899-430-4002) supports manufacturer-approved parallel operation.

The February 2026 commercial specification identifies parallel redundancy with up to four compatible UPS units.

The supported arrangement can use either a common battery bank or separate battery banks, depending on the approved installation.

This capability can help organizations design suitable power systems with additional capacity or redundancy.

However, the older SuperMAX+ technical brochure describes a maximum of three units using a common battery bank.

Therefore, customers planning a four-unit installation must confirm the compatible UPS hardware, firmware, synchronization equipment and electrical configuration with Microtek.

Parallel operation should only be implemented through manufacturer-approved commissioning.

Common or Separate Battery Bank Options

The current commercial description supports two potential battery arrangements for parallel installations.

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

A separate battery-bank arrangement uses an individual battery bank for each UPS.

These configurations have different protection, wiring and operational requirements.

Battery banks must be correctly sized for the entire UPS system and the selected redundancy architecture.

Customers should not change between common and separate banks without manufacturer approval.

Built-In Maintenance Bypass and Static Bypass

The Microtek SuperMAX+ 40KVA Online UPS incorporates built-in maintenance bypass and static bypass functionality.

These features support manufacturer-approved operating and service procedures.

Microtek specifies zero inverter-to-bypass transfer time under the documented conditions.

However, bypass operation can expose connected equipment to the available bypass supply.

Bypass switching and electrical maintenance must be performed by appropriately qualified personnel.

Optional Isolation Transformer

The Microtek SuperMAX+ 40KVA Online UPS is a high-frequency UPS with an optional output isolation transformer.

An isolation transformer is not identified as included in the standard model.

Where electrical isolation is required, an appropriately rated transformer may be specified separately.

This differs from transformer-based Microtek iMAXX UPS models with an inbuilt output isolation transformer.

The transformer should be selected according to the electrical design and the connected load.

Electrical Protection and Generator Compatibility

The Microtek SuperMAX+ Series incorporates overload handling, input surge protection and C3-level electromagnetic interference protection.

The UPS is also compatible with suitable generator supplies.

Generator sizing should account for the connected load, battery charging demand and the generator’s operating characteristics.

Proper grounding, external circuit protection, ventilation and scheduled maintenance remain essential.

The UPS’s protective features do not replace site electrical safety requirements.

Optional Backfeed Energy Absorption Box

Microtek lists an optional backfeed energy absorption box for suitable motor-driven or regenerative-load applications.

Certain electrical equipment may return energy toward the UPS output under specific operating conditions.

Examples can include some lifts, elevators and CNC machines.

The optional accessory can be considered where supported by the machinery and the UPS design.

However, the accessory does not automatically make every regenerative load compatible.

Its electrical rating, wiring and suitability must be confirmed with Microtek before installation.
