Saturn 3/1 20KVA
Share :
This high frequency online double conversion UPS features full digital control and a compact design for a smaller footprint. It operates across wide input voltage and frequency windows with a 0.9 power factor.
The UPS includes an adjustable charger and supports internal or external battery options. It also features self-testing on startup, cold start, auto restart, and a maintenance bypass switch.
Communication interfaces include RS232, USB, and EPO, with SNMP available as an optional feature. Intelligent fan speed regulation and multiple protection functions include short-circuit, overload, overheat, battery overcharge and over-discharge, output low voltage, and fan fault alarm.
