A 3kVA UPS with battery is a 3000 Volt-Ampere uninterruptible power supply system designed to provide backup power during outages. It protects critical equipment like servers, medical devices, and network infrastructure from power fluctuations. Key features include voltage regulation, surge protection, and battery runtime scalability. Ideal for small businesses and residential setups requiring 20-60 minutes of backup power during grid failures.

How Does a 3kVA UPS with Battery Work?

A 3kVA UPS operates in three modes: 1) Normal mode filters utility power, 2) Battery mode activates during outages using stored DC energy converted to AC, and 3) Bypass mode enables direct utility connection during maintenance. The battery bank typically uses 4-8 VRLA (Valve-Regulated Lead-Acid) batteries connected in series to achieve 96V-192V DC input voltage.

The transition between modes occurs seamlessly through automatic transfer switches. In normal operation, the UPS continuously conditions incoming power while charging batteries. During outages, the inverter converts DC battery power to pure sine wave AC within 2-8 milliseconds. Advanced models feature double-conversion technology that constantly powers connected devices through the inverter, eliminating transfer delays completely.
