MICROTEK MAX+ SERIES 3 KVA ONLINE UPS ISO TX WITH EXTERNAL BATTERIES

Product Description

Product Description

Type: True Online UPS (DoubleConversion) with isolation transformer option (ISOTX) suitable for critical power protection with external battery bank.

This UPS ensures clean, uninterrupted power by continuously converting incoming AC mains power to DC and then back to AC providing a pure sinewave output with minimal disruptions. It is ideal for sensitive electronics like servers, networking equipment, computer systems, ATMs, labs, etc.

Key Features & Capabilities

Power & Topology

• Rated capacity: 3kVA / 2700W output.

• Technology: Highfrequency, doubleconversion online with static bypass for higher reliability.

• Pure sinewave output ensures clean, stable AC power for sensitive loads.

Input & Output

• Wide input voltage range: 118V295V AC at <50% load (extends with higher load).

• Output voltage: Selectable 208/220/230/240V AC.

• Frequency: Can be synchronized with mains frequency or fixed at 50Hz (common in India).

• Transfer time: Zero (in online mode) to battery and typically <4ms if switching occurs.

Battery System

• Designed for external batteries (72V DC bus) typically 612V SMF/VRLA batteries in series (battery not included).

• Smart battery charger supports optimized charging and performance.

Protection & Monitoring

• Power Factor Correction (PFC): Helps cleaner and efficient power usage.

• Shortcircuit & overload protection with alarms.

• RS232/SNMP communication options for monitoring and remote management.

• Optional isolation transformer (ISOTX) for added electrical isolation and clean power.

• Generator compatible for use in installations with backup gensets.

Physical & Operational

• Efficiency: 85%92%.

• Low noise: <50dB at 1m with controlled fans.

• LCD/LED display for status, battery, load and fault indications.

In Practical Terms

This UPS is built for continuous operation in areas with unstable mains electricity:

• It keeps sensitive devices running without interruptions.

• With external batteries, you can customize backup time based on battery capacity you choose (e.g., larger AH batteries = more backup time).

• Features like hot standby and static bypass increase uptime and reliability.
