Nice interface design, LCD display the UPS operating status.
Built in control board design, have on need of any adjustment, easy to maintenance.
Overload protection: When overload, setting to auto-transfer, Overload detection and reset,
if overload vanish, auto-transfer to UPS.
Soft start-up protection: When turn-on ups or after turn-off discharge restoration powersupply for ups, avoid transient varying output.
Double reserve power supply system, operation reliability, to ensure power supply or precision equipments.
RS232 communication interface, provide intelligent supervisory software to ups.
The card insertion add-on SNMP(option), support remote supervisory for network.
