This series of products meet the specifications and requirements for the use of electrical equipment related to international and domestic navigation vessels.
1. The combination of software and hardware is adopted for more accurate voltage and current control.
2. Comprehensive protection functions, including input under-voltage, over-voltage protection, output over-voltage protection, output short-circuit protection, over-temperature protection, etc.
3. The power supply has anti-backflow and automatic battery recognition functions. It can adjust its output voltage by detecting the battery voltage at the output end, and supports automatic conversion between 12V and 24V. Identify the battery voltage).
4. User-friendly battery maintenance, three-phase automatic charging (constant current equalization charge-constant voltage equalization charge-floating charge), the cycle of equalization charge and floating charge (1 to 99 days) can be set, the factory default is 15 days.
In order to meet the special needs of customers, special function modules can be selected, such as: remote power on / off, remote manual equalization, remote manual forced charging, 485 communication (non-standard Modbus-RTU485 communication), battery temperature compensation (external temperature) (The probes only support PT100 by default).
It can be used in conjunction with our parallel monitoring module to achieve standard Modbus-RTU485 communication, status monitoring and some parameter adjustment.
Can be used with our battery monitoring module.
Multiple units can be connected in parallel, and automatic current sharing can be achieved when multiple units are connected in parallel.
