China CDHD-60/24 Marine Battery Charger:
Description:
Marine charging power supply is a switching power supply multifunctional charging power supply using high frequency PWM or PFM modulation technology, with IGBT, field effect power tube and pulse width or frequency modulation integrated controller as the main components.
1. Eliminating the bulky and noisy power frequency transformer, the weight of the whole machine is only a quarter of the thyristor charging power supply.
2. The power supply is provided with multiple functional module options. The whole machine adopts intelligent cooling, which can ensure the reliable operation of the power supply even in the high temperature cabin.
3. This charging power supply is a three-stage automatic charging power supply (constant current equalization charging --- constant voltage equalization charging --- floating charging). The entire process of charging the battery is first entered into equalization charging, and the constant current is automatically completed first, and then constant voltage , When the current drops to near zero, the balanced charging is completed, so that it (manual or automatic) will be transferred to "floating charging" to trickle to maintain the battery in a fully charged state.
4. CDHD series marine charging power supply has type approval certificate issued by China Classification Society.
