Online UPS

online_ups
Sigma Power Online UPS generates the pure sine wave output by using the smart Double Conversion technology. It converts the input AC supply to the Dc & then the DC is converted to AC output to ensure the constant 230V output supply on mains & inverter as well.
Thus the output is isolated from the mains input so that the load connected to the output is protected from fluctuations, spikes & surges of the abnormal conditions of the input AC supply.
Power Factor correction technology improves the power factor & saves the electricity up to 40%.

SIGMA POWER On-Line UPS provides True Sign Wave & Regulated Out Put.
