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. |
