PSM-E20

PSM-E20 monitoring system is mainly designed for manufacturers to form DC systems with various capacity configurations. It can be used in power plants, power stations, substations and various types of user transformers and other occasions requiring DC power supply with HD series high-frequency switching rectifier modules and other Emerson acquisition modules PSM-E20 monitoring system to complete intelligent battery management and DC system monitoring and alarm. The PSM-E20 monitoring system has a remote management function and can choose to report data via Modbus, CDT91, DNP3.0, EC101 or IEC103 protocols and the integrated automation system for unmanned power stations.

System composition
The PSM-E20 monitoring system includes the monitoring circuit inside the HD series charging module, the monitoring module (PSM-E20), the power distribution monitoring module (PFU-12 and PFU-13), the insulation monitoring instrument (JYM-1, JYM-I, JYM-M2 and JYM-S2), and the battery detector (BM-1), as shown in the following figure. Intended Audience This document describes the functions, installation design, and commissioning methods of the monitoring module (PSM-E20) and power distribution monitoring module (PFU-12 and PFU-13).
The core modules of the PSM-E20 monitoring system include the PSM-E20 monitoring block, PFU-12 power distribution monitoring, and PFU-13 power distribution monitoring. The following are introduced.

PSM-E20 Monitoring module
1. Use environment
1) Operating temperature :-5℃~40℃
2) Storage temperature :-40℃~85℃
3) Relative humidity :≤95%(40 ℃)
4) Power supply voltage input range :90~300Vdc
2. Function Description
The monitoring module is the data processing center of the monitoring system. Through COM1 to COM4 communication ports, it communicates with PFU-12, PFU-13, HD series charging modules, JYM-II insulation instrument, JYM-1 insulation instrument, and PBM-1 battery instrument to collect the operating data of the power supply system. According to these operating data, the automatic equalization and charging conversion of the battery pack is completed.
If a fault occurs in the power system, the alarm menu is displayed, the alarm indicator is on, and the alarm buzzer is controlled.
The monitoring module can also report the operation data of the power system to the integrated automation system through RS485 or RS232 communication interface according to the user-set communication protocol (Modbus, CDT91, DNP3.0, IEC101 or IEC103 can be selected), and receive the uniform charging control command issued by the integrated automation system to achieve remote control and telemetry.
