2.Product Usage
DDWD-D series power inverter is specially designed for power plants, substations, power supply offices and other power places. Widely used in 220VDC or 110VDC power systems, mainly for closing devices, relay protection, accident lighting and other emergency power system power supply. Through the power plant or substation DC system to obtain electricity, after the corresponding power exchange, the composition of AC-DC dual power supply uninterruptible power supply system.
