    Model： PSM-E20
    Introduce：
Description：

1. Operating Condition
a．Working temperature：-5℃~40 ℃
b．Storage temperature：-40 ℃~85 ℃
c．Relative humidity：≤95%（40±2 ℃）
d．Range of power voltage input：90~300Vdc


2. Function

A. The monitoring module is the CPU of the monitoring system, which can collect the running data of electric operating power supply system by the communication of COM1~COM4 communication port  with PFU-12, PFU-13, HD series charging module, JYM2 insulator, and PBM-1 battery tester, and complete the automatic conversion of equal and float charging of the storage battery set on the basis of these running data. 

B. When the power system is in fault, a pop-up menu for warning will be prompted with the warning LED turned on, and the warning buzzer will be triggered simultaneously. 


C.The module can upload the running data of power system by RS485 or RS232 communication port in accordance with the communication protocol (e.g. Modbus, CDT91, DNP3.0, IEC101 or IEC103) as user required to the integrated automation system and accept the command of equal and float charging control from it to achieve these functions such as remote control, remote measurement and remote signaling.

D. Big and extra clear LCD in conjunction with the button can be used for performing various functions, including setup, review, display, and event record, etc.
