CDHD-20～60A Marine Charging Power Source(complete set)
Product Description
CDHD-20～60A Marine Charging Power Source(complete set)
The marine charging power supply is a switching power supply multifunctional charging power supply that uses 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.
The bulky and noisy power frequency transformer is eliminated, and the weight of the whole machine is only one-fourth of that of the thyristor charging power supply.
The power supply provides multiple functional modules for selection, and the whole machine adopts intelligent cooling, which can ensure the reliable operation of the power supply even in the high-temperature engine room.
This charging power supply is a three-stage automatic charging power supply (constant current balanced charging---constant voltage balanced charging---floating charging). The whole process of charging the battery is to first enter the balanced charging, automatically complete the constant current first, then the constant voltage, and when the current drops to near zero, the balanced charging is completed, and it is turned into "floating charging" (manually or automatically) to trickle to maintain the battery in a fully charged state.
CDHD series marine charging power supplies have a type approval certificate issued by China Classification Society.
