UPS Low Frequency online type,single phase

UPS 3 phase Low Frequency online,LED/LCD display

General (UPS-HB power frequency online HB series UPS)

This series runs in online sine wave made with isolating output transformer, input  under - voltage, over - voltage protection , output under-voltage,over -voltage, over load, short circuit protection. It features high stability , noise filtering and strong over loading. The specially designed static change - over switch  makes  the  zero  transition offers real Uninterrupted power supply. The computer monitoring is optional.
