True Online UPS Technology with DSP-Controlled IGBT Inverter

The Microtek 15KVA iMAXX Online UPS uses low-frequency transformer-based online power conversion with DSP-controlled IGBT inverter technology.

The UPS continuously supplies the protected load through its inverter during normal operation, helping maintain regulated AC output.

Incoming electrical power is processed by the UPS power conversion system before being delivered to connected equipment.

When incoming mains power becomes unavailable, a compatible external battery bank continues supplying energy to the inverter.

Microtek specifies zero transfer time from normal online operation to battery mode, helping minimize interruptions to properly connected equipment.

This technology is particularly relevant to computing systems, network infrastructure and business electronics where sudden power failures could disrupt critical operations.

Three-Phase Input and Single-Phase Output

The Microtek 15KVA/360V iMAXX 3-Phase Input Online UPS features a 3:1 electrical configuration.

The Microtek iMAXX 15KVA Online UPS offers a rated capacity of 15000VA/12000W.

Its 0.8 output power factor provides 12000 watts of rated active output capacity.

This allows the UPS to support appropriately sized professional computing equipment, commercial electronics and other compatible critical loads.

Before installation, the total connected equipment load should be calculated carefully.

The calculation should include continuous consumption, expected operating peaks, equipment starting requirements and suitable headroom.

Maintaining adequate operating headroom can help reduce overload conditions and improve the reliability of the installation.

The connected equipment must remain within the UPS’s electrical and output capacity limits.

Inbuilt Output Isolation Transformer

One of the most important features of the Microtek 15KVA/360V iMAXX Online UPS is its built-in output isolation transformer.

The transformer provides galvanic electrical isolation in the supported output configuration.

This design can help reduce certain types of electrical interference and common-mode noise affecting sensitive electronic equipment.

The transformer is integrated into the UPS cabinet, allowing organizations to use a transformer-based power backup system without specifying a separate output isolation transformer where the built-in arrangement meets application requirements.

However, electrical isolation does not eliminate the need for proper grounding, circuit protection and safe installation.

Specialized industrial and laboratory equipment should be assessed for compatibility before connection.

360V DC External Battery System with Adjustable Battery Quantity

The Microtek iMAXX 15KVA UPS uses a 360V DC external battery system in its standard configuration.

The default setup requires 30 compatible 12V batteries connected in series.

According to Microtek’s technical documentation, the UPS supports adjustable battery configurations of 29, 30, 31 and 32 batteries.

These configurations correspond to nominal battery-bank voltages of 348V, 360V, 372V and 384V DC.

The battery quantity and UPS charging settings must be configured correctly for the chosen installation.

The manufacturer lists compatible lead-acid, tubular and sealed maintenance-free battery types.

Actual backup duration depends on installed battery capacity, connected load, battery condition, ambient temperature and system efficiency.

External battery racks, DC cables, battery breakers and other installation accessories should be selected as part of the complete electrical design.

20 Amp Inbuilt Battery Charger

The Microtek 15KVA/360V iMAXX Online UPS includes an inbuilt battery charging system with 20A charging capability.

The manufacturer identifies this charging capacity as a feature of its 360V iMAXX models.

The older technical table lists a default charging-current setting of 5A, with available charging current dependent on the manufacturer’s operating conditions.

Customers should therefore distinguish the 20A charger capacity from the charger’s configured operating current.

The correct charging arrangement depends on battery capacity, battery specifications, electrical load and UPS configuration.

For a high-voltage external battery system, charging settings should only be adjusted according to approved manufacturer instructions.

This model should not automatically be assigned the additional 4A charger option listed for certain 192V iMAXX models.

Pure Sine Wave Output with Stable Voltage Regulation

The Microtek iMAXX 15KVA Online UPS provides pure sine wave output during battery operation.

Pure sine wave power supports reliable operation of many compatible electronic power supplies and professional IT devices.

The manufacturer specifies a default output of 230V AC with approximately ±1% regulation.

Output voltage can be configured to supported 208V, 220V or 230V settings.

Its specified output harmonic distortion is below 2% for linear loads and below 5% for non-linear loads.

The UPS provides a battery-mode output frequency of approximately 50Hz ±0.1Hz.

These features help maintain consistent AC output quality for suitably designed electrical installations.

Parallel Redundancy for Critical Power Applications

The Microtek 15KVA/360V iMAXX 3-Phase Input Online UPS supports manufacturer-approved parallel redundancy configurations.

The February 2026 commercial specification lists parallel redundancy for a maximum of two UPS units.

Parallel redundancy can improve system availability by allowing suitably configured UPS units to operate together as part of a redundant power architecture.

However, parallel capability depends on compatible UPS hardware, communication interfaces, batteries, protective devices and commissioning procedures.

A separate manufacturer brochure describes a higher parallel-unit limit for the 360V iMAXX range.

Therefore, customers should confirm the exact supported parallel configuration with Microtek before purchasing equipment for a redundant installation.

Parallel operation must never be assumed to work simply by connecting multiple UPS outputs together.

Hot Standby and Cold Start Features

The Microtek iMAXX Series also supports Hot Standby and Cold Start functionality.

Hot Standby allows manufacturer-approved standby arrangements to be considered for installations requiring additional power continuity.

For the 360V models, separate battery banks may be required in the manufacturer’s recommended standby arrangement.

Cold Start supports UPS startup from an appropriately connected and sufficiently charged battery bank when mains power is unavailable.

These functions provide operational flexibility for professional power backup projects.

Hot Standby and parallel redundancy are different arrangements; the correct configuration should be selected according to the installation’s requirements.
