Product Description
CWHD-20~30A Marine Voltage Regulator(module core)
The marine stabilized power supply is a switching power supply type multifunctional stabilized 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 marine stabilized power supply is small in size, easy to install, and has optional additional functions.
The marine stabilized power supply adopts intelligent cooling to ensure reliable power supply operation even in a high-temperature engine room.
The marine stabilized power supply has a stable output, and the output voltage and output current can be set according to requirements; the output voltage and current range can also be adjusted through a potentiometer.
