Intelligent ATS Controller

Features:
1) Uses as key components of automatic transfer switch. It can provide 
    reliable, intelligent control for ATS whose frequency is 50 or 60Hz, and
    rate voltage up to 400V, voltage by one or three phase, CB class or 
    PC class
2) Centers on technical grade MPU of high performance, by examining the 
    3-pole voltage from two incoming line on real time, then make exact 
    judgment to the voltage abnormity (such as 110% over voltage, 85% 
    under voltage, unbalance) appearing in the power supply circuitry, and
    control the ATS switching through delay time
3) In order to meet the demands of the scene application, the controller 
    supplies main line lord use, secondary line lord use, equal, manual 
    working mode
4) Switch-mode power supply, even the voltage is as lower as 85V
5) User-friendly operation with 4 operation mode 
    supports, manual switch on/off on panel
6) 1 pole/3-pole ATS
7) 35mm DIN and Panel cut-out installation
8) LED/LCD display
9) RS-232, RS-485, Modbus, CAN, Profibus-DP, DeviceNet supported
10) AC-AC, AC-DC, DC-DC
