Microtek SuperMAX+ 60KVA ISO Transformer Online UPS – Advanced Three-Phase Power Backup

The Microtek SuperMAX+ 60KVA Dual Input Online UPS with Inbuilt Isolation Transformer (899-431-60TX) is a high-capacity power backup solution designed for commercial electrical infrastructure, institutional facilities, professional IT installations and compatible critical three-phase equipment.

Featuring advanced Digital Signal Processing (DSP) technology, a high-frequency inverter, an inbuilt output isolation transformer, an 18A inbuilt battery charger and a 5-inch touchscreen LCD, the Microtek SuperMAX+ Series combines dependable online power protection with advanced monitoring and redundancy options.

The model supports three-phase input and three-phase output (3:3), dual input functionality and an adjustable external battery system containing 32 to 40 compatible batteries.

The SKU-specific commercial specification identifies a 0.9 output power factor, corresponding to a calculated active-power capacity of 54KW at 60KVA. Microtek’s broader technical brochure gives a different unity-power-factor rating for its 60KVA isolation-transformer family, so the exact output rating for SKU 899-431-60TX should be confirmed before final system sizing.

Manufactured by Microtek, this UPS is intended for professionally engineered power installations where electrical continuity and suitable output isolation are important.

True Double-Conversion Online UPS Technology

The Microtek SuperMAX+ 60KVA Online UPS uses true double-conversion technology.

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

The inverter continuously powers supported equipment, helping reduce the effects of input voltage fluctuations and other disturbances within the UPS operating range.

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

Microtek specifies zero normal transfer time between online operation and battery mode.

This is valuable for compatible electronic systems where sudden power interruption can lead to equipment shutdowns or disruption of essential processes.

60KVA Capacity with 0.9 Power Factor

The Microtek 60KVA SuperMAX+ ISO Transformer UPS is listed at 60KVA with a 0.9 output power factor in the February 2026 commercial specification.

Using these two ratings, the calculated active-power capacity is 54000W.

The broader manufacturer brochure lists 60KVA/60000W for its 60KL isolation-transformer model. Because these published values differ, the exact wattage of the supplied SKU must be verified with Microtek.

Businesses should calculate connected equipment requirements using confirmed active-power and apparent-power ratings.

The final assessment should include continuous consumption, startup characteristics, phase loading, suitable headroom and any output-voltage derating.

Three-Phase Input and Three-Phase Output

The Microtek SuperMAX+ 60KVA Dual Input Online UPS operates with three-phase electrical input and three-phase output.

This configuration is commonly referred to as a 3:3 Online UPS.

Microtek’s 60KL isolation-transformer brochure specifies a nominal 3 × 400V AC input with three phases and neutral.

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

This electrical arrangement is suitable for professionally designed installations that require regulated three-phase power.

The manufacturer specifies an additional 90% output-power derating at its 3 × 360V AC setting.

Actual available power at that voltage must be calculated using the confirmed model-specific rated wattage.

Inbuilt Output Isolation Transformer

The most important distinguishing feature of SKU 899-431-60TX is the inbuilt output isolation transformer.

The transformer provides galvanic isolation within the supported UPS output arrangement.

Electrical isolation may help reduce certain common-mode disturbances and provides separation between the applicable input and output electrical circuits.

This feature is valuable for installations where an output isolation transformer forms part of the electrical design.

Unlike the transformerless Microtek SuperMAX+ 60KVA model 899-431-6002, the 60TX variant incorporates the isolation transformer into its cabinet.

An isolation transformer does not remove the need for proper grounding, circuit protection, electrical safety devices or compliance with applicable standards.

Dual Input Design

The Microtek SuperMAX+ 60KVA UPS incorporates a dual input design.

This allows approved arrangements with a separate bypass input source or compatible Hot Standby-related configurations.

The feature may assist organizations planning power systems with multiple suitable AC supply paths.

However, dual input should not be interpreted as automatically increasing output capacity.

Rectifier input, bypass input, electrical protection, source synchronization and switching arrangements must follow Microtek’s approved engineering instructions.

DSP-Controlled Three-Level Inverter Technology

The Microtek SuperMAX+ 60KVA ISO Transformer Online UPS uses advanced DSP control and three-level inverter technology.

DSP-based management helps regulate electrical conversion, operating conditions and system monitoring.

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

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

This is an input-side specification and must not be confused with the 0.9 output power factor listed for the exact SKU.

External 32–40 Battery System

The UPS operates with a high-voltage external battery system.

The supported manufacturer battery range is 32 to 40 compatible 12V batteries in a centre-tapped arrangement.

A 32-battery system corresponds to nominal ±192V DC, while a 40-battery system corresponds to nominal ±240V DC.

The battery midpoint, positive and negative connections must be made according to the approved Microtek wiring arrangement.

Different battery quantities require compatible charging and UPS configuration.

Since this is a high-voltage DC system, battery installation must be performed by trained professionals using properly rated electrical protection.

Minimum 40 × 100Ah Battery Recommendation

The February 2026 commercial specification for Microtek 899-431-60TX recommends a minimum of 40 batteries rated at 100Ah each, subject to the actual connected load.

This recommendation is especially relevant when planning a complete 60KVA installation.

Although the UPS supports a wider technical battery-count range, the lower configurations should not automatically be assumed suitable for every installation.

Required backup duration depends on electrical load, battery capacity, battery discharge characteristics, operating temperature and battery condition.

A battery-sizing calculation should be completed before purchase.

18 Amp Inbuilt Battery Charger

The Microtek SuperMAX+ 60KVA Online UPS includes an 18A maximum inbuilt charger.

The isolation-transformer series brochure identifies adjustable charging current from 2A to 18A for its 60KVA configuration.

This allows suitable charging settings to be selected for the installed battery system.

Charging current must be configured according to battery specifications, UPS operating requirements and manufacturer-approved instructions.

The maximum charger rating should not automatically be used for every battery capacity.

Pure Sine Wave Output

The Microtek SuperMAX+ Series provides pure sine wave output during battery operation.

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

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

The isolation-transformer 60KL technical table lists output harmonic distortion of 2% or less for linear loads and 10% or less for non-linear loads.

These values differ from the transformerless version and should not be interchanged.

5-Inch Touchscreen LCD Monitoring

The Microtek SuperMAX+ 60KVA ISO Transformer Online UPS features a 5-inch touchscreen LCD.

The display presents important UPS operating information, including connected load percentage, output current on each phase, electrical input and output conditions, and battery information.

It can also show operating temperatures, event logs and fault indications.

Microtek specifies event-log storage for up to 500 events in the 60KL series literature.

This interface is useful for facility managers and electrical maintenance teams responsible for critical power infrastructure.

Parallel Redundancy with Up to Four UPS Units

The Microtek 899-431-60TX supports manufacturer-approved parallel redundancy with up to four compatible UPS units.

The SuperMAX+ technical brochure describes parallel operation using either an approved common battery bank or separate battery banks for individual UPS units.

Parallel operation may support greater system availability or capacity in a properly engineered power installation.

However, actual usable power and redundancy depend on the confirmed output rating, installed number of UPS units and the approved system architecture.

Synchronization, communication cables, current-sharing cables, battery protection and power wiring must be correctly selected.

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

ECO Mode and Operating Efficiency

The isolation-transformer version of the SuperMAX+ 60KL Online UPS supports ECO operating mode.

Microtek’s isolation-transformer series brochure specifies approximately 87.5% AC-mode efficiency, 93.5% ECO-mode efficiency and 86.5% battery-mode efficiency under stated test conditions.

These figures are different from those of the lighter transformerless version.

The built-in transformer provides an electrical isolation benefit, but also contributes to the UPS’s greater size, weight and conversion losses.

ECO mode should only be selected after assessing the connected equipment’s power-quality and continuity requirements.

Generator Compatibility and Bypass Features

The Microtek SuperMAX+ 60KVA UPS supports suitable generator supplies.

Generator selection should account for connected equipment, battery charging demand and UPS input characteristics.

The product family also offers maintenance bypass and Emergency Power Off functions.

These features support approved maintenance and safety arrangements, but must be used according to the manufacturer’s instructions.

Bypass operation can expose connected equipment to the quality of the available bypass source.

Communication and Remote Monitoring

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

Optional SNMP management can enable remote supervision through suitable network management software or a web browser.

These interfaces can help organizations monitor critical electrical infrastructure.

Communication accessories should be confirmed in the purchase quotation.

Optional Backfeed Energy Absorption Box

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

Some elevators, lifts and CNC machines can return electrical energy during particular operating conditions.

Such energy can cause a UPS internal DC-bus overvoltage fault if the power system is not designed to manage it.

A correctly sized and approved absorption accessory may be necessary for these applications.

However, the UPS and accessory must be evaluated against the actual machinery before connection.

Heavy-Duty Floor-Standing Cabinet

The Microtek SuperMAX+ 60KVA Online UPS with Inbuilt Isolation Transformer uses a heavy-duty floor-standing cabinet.

The manufacturer’s 60KL isolation-transformer datasheet specifies dimensions of approximately 790 × 720 × 1060 mm and a net weight of 440kg, excluding external batteries.

This is substantially heavier than the transformerless 60KVA SuperMAX+ model.

The installation site must be assessed for floor-loading capacity, safe equipment movement, ventilation, maintenance clearance and electrical access.

Before dispatch, customers should confirm the final cabinet drawing and shipping dimensions for the exact supplied model.

Package Exclusions and Installation Accessories

The commercial description of SKU 899-431-60TX specifically excludes:

• Battery links
• Input cables
