3. Product Feature And Application of The Wall Mounted DC Panel


Product Features:

Wall-mounted installation, small space occupation, good economy.


Two AC inputs are switched automatically to ensure the normal operation of the system; One of them can choose PT100VAC power supply, automatic power output limit PT power supply.


Wide input voltage range and strong grid adaptability.


High frequency switching power supply technology, modular design, N+1 hot backup, high reliability.


Rectifier module and step-down module adopt live plug structure, convenient installation and maintenance.


Main monitor adopts large LCD display, Chinese characters menu, friendly interface, simple and flexible operation.


The main monitoring system has the function of automatic management of batteries. The monitoring system can automatically accurately manage battery voltage, charge and discharge current and battery temperature compensation, and has over-voltage and under-temperature alarms and fault alarms.



Ensure that the battery works in the best state, prolong the service life of the battery.


The master monitor monitors and controls the system in real time, and can set parameters, query information and calibrate parameters.


The master monitor can communicate with the remote monitor to implement the four remote functions of "telemetry, remote control, remote communication and remote adjustment" for the system to realize unattended. Provides RS232, RS485 two kinds of communication interface, and CDT, MODBUS.


Two Communication Protocol Options:

The system has the function of insulation detection for the bus output. When the insulation of the bus is reduced, the system will have sound and light alarm to eliminate potential safety hazards.


Optional battery inspection function.
