Four 300W line DC power supply, the use of pure copper toroidal transformer, high efficiency, small heat.LED intuitive display voltage, current and output power, with 10mV/1mA high-precision resolution; with short-circuit, over-voltage, over-current, reverse polarity protection, high stability, reliability; a key to control the output on and off switch, convenient and safe. Widely used in product aging maintenance, battery charging, experimental testing, production testing, electrolysis plating and other industries.

The cabinet-type high-power switching power supply adopts a frame-type 3U chassis, which is convenient for equipment integration and installation. Four-digit LED visually displays voltage, current, output power and output equivalent impedance, with 10mV/10mA resolution; coding switch digitally controls the output size, which is convenient and durable; with short circuit, overvoltage, overcurrent, overpower, reverse polarity protection Function. High output efficiency, one-button control output on-off switch, convenient and safe. Standard RS232, RS485 and USB serial port communication, support MODBUS RTU protocol, realize automatic control; widely used in cabinet equipment integration, product aging test, battery charging, experimental test, production test, electrolytic plating and other industries;
