Description:
2.1 Quasi sine wave output
PG series, UPS/Inverter are quasi sine wave output to provide best power supply for loading equipment whether in grid electric power or battery power condition.
2.2 Fast and intelligent charge
Normal fast charge could easily cause over charge, ordinary charger speed is too slow, however, the PG series, UPS, Inverter adopt a smart charge mode makes charging fast and reliable, while improving battery cycle life.
2.3 Regulated output free from mixed signal
Under grid power supply, PG series, UPS, Inverter can effectively filter out surge and the kind of signal
