As a part of the EV control system, DCL converts high-voltage battery voltage into low-voltage output under the control of the main controller, supplying power to low-voltage electrical equipment on the vehicle. The output terminal has a low-voltage battery; Require stable output voltage, high conversion efficiency, precise structure, compact size, high reliability, and protection functions such as input overvoltage and undervoltage, output overvoltage and undervoltage, output short circuit, input anti reverse connection, and overheating.
