Product Description
CJHD-20A 220V Single Phase Marine Charging Power Source(Complete Set)
CJHD-20A marine charging power supply adopts high-frequency PWM or PFM modulation technology, and is a switching power supply type multifunctional charging power supply composed of IGBT, field effect power tube and pulse width or frequency modulation integrated controller as the main components. The performance is stable and reliable.
Protection function: input over-voltage and under-voltage protection, output under-voltage alarm, output over-voltage, over-current and short-circuit protection, overheating protection.
Input and output isolation, output end backflow prevention.
Humanized battery maintenance, three-stage automatic charging (constant current equalization charging-constant voltage equalization charging-floating charging).
With passive contact comprehensive fault alarm function.
