Online UPS for Critical Systems

About Online UPS for Critical Systems

Reliable Power Protection for Mission-Critical Operations

What is an Online UPS?

An Online UPS, also known as Double Conversion UPS, is a power protection system that

provides continuous, clean, and uninterrupted power to connected loads. Unlike offline or line-

interactive UPS systems, an online UPS completely isolates the load from the utility power,

offering the highest level of power quality and reliability.

Principle of Operation Double Conversion Technology

1. AC-DC Conversion (Rectifier):

Incoming AC power is converted into DC power.

2. Battery Charging & DC Link:

The rectified DC power charges the battery and powers the inverter simultaneously.

3. DC-AC Conversion (Inverter):

The inverter converts the DC back into clean, regulated AC power that feeds the load.

The inverter converts the DC back into clean, regulated AC power that feeds the load.

4. Seamless Backup:

During a power outage, the battery continues to supply DC to the inverter without any

transfer time, ensuring zero break in power.

transfer time, ensuring zero break in power.

Because of this continuous conversion, the load always receives isolated, noise-free, and

regulated power ideal for sensitive electronics.
