DC screen charging module monitoring unit PM3D PM3A PM3K

PM3D functional features

Measure the voltage of the two sections, the voltage and current of the controller, the voltage and charging and discharging current of the two groups of batteries, and the ambient temperature.

The detected information is transmitted to the master monitor over the RS485 serial port for the master monitor to manage the power system and handle fault alarms.

Four extended measurement channels are provided to measure the operating parameters of the system extension equipment (input voltage 5V).

Current measurement supports two measuring modes: Hall current sensor measurement and shunt measurement.

Voltage measurement using the common negative terminal direct measurement.
