Advanced DSP Technology with IGBT-Based Inverter

The Microtek 20KVA iMAXX Online UPS uses Digital Signal Processing technology with an IGBT-based inverter to manage electrical power conversion and output regulation.

Unlike a conventional standby UPS, an Online UPS continuously delivers regulated power through its inverter during normal operating conditions.

The incoming electrical supply is processed before power reaches connected equipment, helping reduce the impact of many electrical disturbances.

When mains electricity fails, the external battery bank supplies energy to the inverter without a normal transfer delay.

Microtek specifies zero AC-to-battery transfer time during supported online operation.

This helps maintain power continuity for compatible electronic equipment during unexpected interruptions.

Three-Phase Input and Single-Phase Output

The Microtek 20KVA/360V iMAXX Online UPS is designed for three-phase electrical input and single-phase output.

Its nominal input supply is specified as 380V, 400V or 415V AC across three phases, with the appropriate neutral and earthing arrangement.

The UPS delivers a regulated single-phase AC output, with 230V as the default output voltage.

Supported selectable output voltages include 208V, 220V and 230V AC.

This configuration is relevant to offices, commercial buildings and institutional facilities where three-phase electricity is available, but critical equipment requires protected single-phase power.

It must not be confused with the Microtek iMAXX 20KVA three-phase output version, which uses a different manufacturer part number.

Electrical installation and load distribution should be designed by a qualified professional.

20KVA/16000W Output with 0.8 Power Factor

The Microtek iMAXX 20KVA Online UPS provides a rated output capacity of 20KVA/16KW.

Its 0.8 output power factor gives the system a rated active power capacity of 16000 watts.

This makes the UPS suitable for properly sized professional computing equipment, networking infrastructure, compatible server systems and commercial electronics.

Before selecting a high-capacity UPS, organizations should calculate the combined continuous power requirements of connected equipment.

The load assessment should include startup current, operating peaks, electrical characteristics and suitable headroom.

Correct UPS sizing reduces the risk of overloading and helps improve the reliability of business-critical electrical installations.

Inbuilt Output Isolation Transformer

One of the key features of the Microtek 20KVA/360V iMAXX 3-Phase Input Online UPS is its inbuilt output isolation transformer.

The transformer provides galvanic isolation within the supported output configuration, offering electrical separation between the relevant power circuits.

This can help reduce certain types of common-mode electrical noise and interference.

Transformer-based UPS systems are often considered for professional installations where isolation is an important electrical design requirement.

The Microtek iMAXX model integrates the output transformer inside the UPS cabinet.

However, isolation does not eliminate the need for proper grounding, protective devices, electrical safety procedures or equipment-specific compatibility checks.

360V DC External Battery System

The Microtek 20KVA iMAXX Online UPS uses an external high-voltage battery system.

The default configuration requires 30 compatible 12V batteries connected in series, forming a nominal 360V DC battery bank.

The commercial product details also specify supported 31-battery and 32-battery configurations.

According to the manufacturer’s technical brochure, the 360V iMAXX range additionally supports a 29-battery setting under the appropriate configuration.

These battery quantities correspond to different nominal DC voltages and must only be used after the UPS settings have been correctly configured.

The manufacturer identifies lead-acid, tubular and sealed maintenance-free batteries as suitable battery categories, subject to approved specifications.

Actual backup duration depends on battery capacity, connected load, battery health, UPS efficiency and environmental conditions.

The UPS itself does not contain the external battery bank as standard.

Battery Voltage Configuration and Backup Planning

External battery selection is an important part of the complete UPS installation.

For the default 30-battery configuration, the nominal battery voltage is 360V DC.

A supported 31-battery arrangement provides 372V DC, while a 32-battery arrangement provides 384V DC.

Any change in battery quantity requires the correct manufacturer-supported charger settings and appropriate protection equipment.

Customers requiring longer backup should select a compatible battery capacity after calculating their actual electrical load and required runtime.

The battery rack, DC circuit breaker, interconnecting cables and other protection accessories should be considered during procurement.

Because the system operates at hazardous DC voltages, battery installation must be performed by qualified personnel.

20 Amp Inbuilt Battery Charger

The Microtek iMAXX 20KVA Online UPS incorporates a 20 Amp inbuilt charger.

This provides charging capability for properly configured external battery systems.

The manufacturer’s older technical datasheet lists a default charging-current setting of 5A.

The actual available charging current depends on battery voltage, UPS load and the approved system configuration.

This distinction is important because a charger rated at 20A does not necessarily deliver 20A continuously under all operating conditions.

Charging settings should be selected according to the installed batteries and Microtek’s technical guidance.

Correct charging configuration helps maintain battery readiness and supports dependable backup operation.

Pure Sine Wave Output with Stable Voltage Regulation

The Microtek 20KVA/360V iMAXX Online UPS provides pure sine wave output during battery mode.

Pure sine wave output supports stable electrical operation for many compatible professional electronic systems and power supplies.

The manufacturer specifies an output voltage regulation of approximately ±1%.

It also lists total harmonic distortion limits of less than 2% for linear loads and less than 5% for non-linear loads.

The output frequency can be synchronized with the incoming mains supply or controlled in battery operation according to the specified settings.

These characteristics support dependable power quality for appropriately connected equipment.

Parallel Redundancy for Critical Power Systems

The Microtek 20KVA/360V iMAXX Online UPS supports manufacturer-approved parallel redundancy.

The commercial specification effective February 2026 lists a maximum two-unit parallel redundancy configuration.

Parallel redundancy allows compatible UPS units to be installed in an approved power architecture to improve system availability.

This can be useful for organizations seeking additional protection against an individual UPS unit failure.

Parallel installations require correct synchronization, compatible communication hardware, approved wiring and appropriate battery-bank arrangements.

A separate June 2025 manufacturer brochure describes a maximum three-unit configuration for the 15KVA and 20KVA 3:1 models.

Therefore, the exact supported unit count must be confirmed against the supplied hardware and firmware revision.

Hot Standby and Cold Start Functionality

The Microtek iMAXX Series includes Hot Standby and Cold Start functions.

Hot Standby supports approved standby arrangements where a compatible additional UPS can serve as backup.

For 360V iMAXX models, the manufacturer’s updated brochure describes separate battery-bank requirements for supported standby arrangements.

Cold Start permits UPS startup from a correctly connected and sufficiently charged battery bank under supported conditions.

These features provide additional flexibility for professional power backup installations.

Hot Standby and parallel redundancy are not identical operating configurations, so the required system design should be confirmed before commissioning.
