Product Description
HDW AC-DC 20A Marine Voltage Regulator(mould core)
This series of products meets the use specifications and requirements of electrical equipment related to international and domestic ships.
The combination of software and hardware makes the voltage and current control more accurate.
The protection functions are comprehensive, including input undervoltage, overvoltage protection, output overvoltage protection, output short circuit protection, overtemperature protection, etc.
In order to meet the special needs of customers, special function modules can be selected, such as: remote power on and off, 485 communication (non-standard Modbus-RTU485 communication).
It can be used with our parallel monitoring module to realize standard Modbus-RTU485 communication, status monitoring and some parameter adjustment, etc.
