MICROTEK 120 KVA ONLINE UPS 3 PHASE IN 3 PHASE OUT without isolation transformer

Product Description

Product Description

The Microtek 120KVA Supermax+ Online UPS is a highcapacity, industrialgrade true online (doubleconversion) UPS system designed for critical threephase power backup applications. It provides uninterrupted, clean, stable power to sensitive electrical and electronic loads in commercial buildings, data centers, industrial facilities, and critical infrastructure.

Key Features & Functionality

Online DoubleConversion Topology

• Converts incoming AC to DC then back to AC to supply power continuously, keeping output waveform stable and free of disturbances even during grid fluctuations or outages.

• Zero transfer time ensures connected equipment never loses power.

HighPerformance Power Delivery

• Rated Capacity: 120kVA (up to 108kW at 0.9 PF).

• Output Voltage: 400V / 415V (3phase) with pure sine wave output.

• High Efficiency: 94% at full load.

• Output Distortion (THD): <3% for linear load.

• Crest Factor: 3:1; handles nonlinear loads effectively.

Input Characteristics

• Input Power Factor: 0.99 (reduces stress on supply).

• Wide Input Voltage & Frequency Tolerance: Operates through dips/surges and under unstable mains without switching to battery immediately.

• 3phase Input & Output: Ideal for balanced, largescale loads.

Battery & Runtime

• Uses external battery bank with flexible battery options (SMF, LiIon, Flooded).

• DC Bus: 384480VDC.

• Backup runtime depends on battery bank capacity; modular setups allow extended runtime.

• Optional battery circuit breaker and charger settings.

Additional Features

• Builtin static bypass: Provides power continuity in case of internal UPS faults.

• Parallel configuration: Up to 4 units can be paralleled for redundancy or increased capacity.

• Generator compatibility: Works seamlessly with diesel or other standby generators.

• Communication interfaces: RS232 and USB ports; optional SNMP for network monitoring.

• LCD Display: Shows realtime UPS status, alarms, and parameters.

• Safety: Audible alarms and visual indicators for faults and warnings.

Optional Accessories

• Isolation Transformer: Can be added externally if required by site or electrical code not mandatory by design.

• Parallel Synchronization Kit: Available for multiUPS setups.

• SNMP Network Card: For remote management.

Typical Applications

Ideal for facilities that cannot tolerate power interruptions and require consistent threephase power:

• Data centers, server farms

• Manufacturing automation systems

• Telecom infrastructure

• Critical medical equipment

• Commercial buildings / IT networks

• Control rooms and PLCbased systems where clean, reliable power is essential.
