SY-PC1000 Intelligent Power Monitoring Unit
1. Overview
SY-PC1000Intelligent power monitoring unitSpecially designed for monitoring and controlling dual power switch ATS (Automatic Transfer Switch) to ensure the continuity, safety, and reliability of power system operation. This monitoring unit integrates switch and logic control, with higher switching reliability and more complete functions. It also integrates bus power monitoring, energy calculation, feeder monitoring and other functions, and can be connected to a remote monitoring system as needed; Free selection of six working modes to meet users' diverse needs; The four remote functions make it more convenient for users to connect to the internet.
SY-PC1000 has the remarkable advantages of advanced technology, perfect performance, safety and reliability, high degree of automation, convenient operation, wide application, etc. It is very suitable for substations, power plants, communication machine rooms, banks, hospitals, shopping malls, chemical industry and other important electric fields that are not allowed to cut off power or are unattended.

4. Function Introduction
4.1 AC power collection
Sample two incoming line voltages and frequencies;
Sampling bus voltage, current, frequency, power, power factor, and cumulative electrical energy;
Communicate fault alarms or actions.
4.2 Communication Dual Channel Switching ATS Control and Monitoring
Switching management of two-way communication incoming lines, controlling the switching of ATS, monitoring the working status of ATS, and displaying the working status; Six built-in work management modes are used to operate ATS, as follows:
Fixed 1 route
Fixed 2 routes
Priority along the way
Two way priority
Two way automatic
Stop power supply
4.3 Protection Function
The low current grounding protection function monitors the zero sequence current of the busbar and takes protective actions based on the set value.
The busbar overcurrent protection function monitors the busbar current and activates the protection with a set delay when it exceeds the set value.
4.4 Events and alarms
Real time recording of alarm events, no loss in case of power failure, event time resolution of 1ms, capable of recording the occurrence time, event name, and related power data of the event; It can be uploaded to the comprehensive automation system or viewed on the interface, which can be used to analyze the causes of faults or events.
Partial alarms can be output through signal relays, with a maximum of 16 outputs.
4.5 Remote Communication Function
Equipped with two standard RS485 interfaces, it can be directly connected to the integrated automation control system using MODBUS protocol and perform "four remote" operations in the upper computer.
In the remote control mode, the remote computer can remotely adjust and control the monitoring unit; In local mode, remote control and adjustment are not allowed, but time synchronization is allowed.
4.6 Feedline Management
The monitoring unit itself can manage up to 24 passive alarm signals from switches, and multiple switch monitoring modules can be extended through independent RS485 ports to collect the status of feeder switches; Reserve expansion interfaces for current monitoring of each feeder line.
