2.Product Usage

DDWD-D series communication dedicated inverter power supply mainly completes the inverter process from DC to AC, in different applications can be set AC main supply or DC main supply (DC source from the battery). This series of inverter power supply is specially designed for the post and telecommunications industry, suitable for 48V or 24V program-controlled switches, computer rooms, networks, billing servers, emergency lighting and other related loads. If the mains power fails or exceeds the normal range, the output automatically switches to DC inverter power supply.
