Online UPS

Listing ID #1704336

We are offering online ups.
Microprocessor based double conversion topology.
At input stage ac supply is converted to controlled dc and in second stage dc is converted to controlled ac which is used to support the critical loads. Due to double conversion the load is completely protected against spikes, surges and brownouts. Use of microprocessor ensures low component count and reliability of the circuit.
Active poser factor correction at ups input
at input stage conversion from ac to controlled dc is achieved through high frequency pwm based converter using igbts. This technology offers following benefits to the user.
Input power factor >0.95
very low input current distortion, input current wave form similar to sine wave, no harmonics will be reflected back to mains, thus no pollution of the input mains.
Ups can operate with almost same capacity generator.
Auto correction for input phase rotation reversal
reduced size of cabling and switchgear at the input stage.
