Monitor PSM10A

1、 Function Introduction:

1Intelligent battery charging management function, fast response time, stable current limit value, and extended battery life;

2Complete remote communication function, throughRS232/RS485Implement the "four remote" function of the interface to achieve unmanned operation;

3Complete alarm processing and recording functions. When the system is abnormal, the monitoring system automatically generates sound and light alarms, and the status on the screen displays "fault" after the status, and the fault output node takes action;

4System operating parameters can be set on-site (or remotely), with upper and lower limit alarms and manual float charging conversion;

5Monitor the voltage and current of each DC feed output, as well as the status of each feed output switch, fuse, insulation, and lightning arrester. When abnormal situations occur, sound and light alarms will be issued;

6Three phase AC voltage detection,Overvoltage, undervoltage, phase loss, power outage alarm;

7. Detectable13The status or tripping alarm of the feeder switch in the road branch line can be triggered, and can be passed throughRS485Maximum interface expansion40Road switch quantity, equipped with a switch quantity box;

8According to user needs, it can be achieved throughRS485Interface extension24Road battery inspection(match1Battery Inspection Unit)；

9According to user needs, it can be achieved throughRS485Interface extension30Road branch insulation monitoring unit;

10There is4Road configurable switches(Passive dry contact)Output, among which3The road can be set to7Level silicon chain control;

11The working power supply of the system comes from the busbar voltage, which is equipped with anti reverse diodes. However, it is still necessary to strictly prevent positive and negative reverse connections when wiring;

12It has a protective function for the battery. When overvoltage is detected in the busbar voltage, the monitoring system will automatically operate the module at a safe voltage,15After minutes, the system will restore the module to normal voltage operation. If the system is still working in the overvoltage state of the busbar, it will work2Minutes, enter again15The security status of the module in minutes,...... Until the overvoltage fault of the system's busbar voltage is resolved;

13The voltage, current, and time data of the system are all adjusted through software. After the machine leaves the factory, do not open it again to adjust various parameters;

14The history record has a power-off saving function. For faults that have not been resolved due to the last power outage, the end time is for all of them00-00 00:00To show differentiation;

15The backend is485and232Interface, providingMODBUSTheCDTTwo communication protocols, it is believed thatMODBUSagreement.
