CJHD-20/24A Marine Battery Charger Power Supplymultifunctional charging power source composed of IGBT, field effect power tube and pulse width or frequency modulation integrated controller using high frequency PWM or PFM modulation technology. Stable and reliable performance.
1. Protection functions: input overvoltage and undervoltage protection, output undervoltage alarm, output overvoltage, overcurrent and short circuit protection, and overheating protection.
2. The input is isolated from the output and the output is protected against backflow.
3. User-friendly battery maintenance, three-stage automatic charging (constant current equalization charging-constant voltage equalization charging-floating charging).
4. With passive contact comprehensive fault alarm function.
