Pure Sine Wave Inverter Combined charger 70A Pure sine wave Low frequency inverter charger, 220vac/110vac (LW series) 70AMP built in charger. 12V-24V-48vdc, 1000W-6000W, UPS function It widely applied in wind Generator, Solar battery pack set, house, vehicle, ship, navigation and places where lack of main power, mobile electricity work also telecommunications device, launch Station, Emengency EPS and so on. LW Series Pure Sine Wave Inverter takes low frequency converter Device, with built in Isolation transformer. Zero Voltage(ZV) and soft switch technic, high capability Motorola MCU, digital and dummy combined technics which Complete the voltage increase in one time and SPWM wave modemed Advanced circuit, high efficiency and compact size, small weight And super stability It has no repellency for the load, which can work well with Inductive load such as fluorescent lamp, electromotor, microwave ovens, Induction cooker, refrigerator, air conditions and transformer. With protection fonction like, DC input protect When pole wrong, AC input protection against over and low voltage, Output protection against over load, shor circuit Protection, DC input and AC output completely electric insulation.
