SKR2-A automatic transfer switch controller is based on the micro-processor core.It can accurately detect the three phases/single phase voltage of the dual power supplies,make accurate judgement of voltage anomalies (power loss,over voltage,under voltage,phase missing,over frequency,under frequency),and control the switching of ATS after delay.
1.LCD is 128*84,with backlight,two languages (Simplified Chinese and English)display,buttonoperation.;
2.Has functions of over voltage,under-voltage ,phase loss,reverse phase sequence,over frequencyand Under-frequency:
3.Has automatic /manual state,in manual mode,it can be forced to switch on or off;
4.All parameters are programmable on site,using two level password to prevent non professional toincorrect operate:
5.Apply to one breaking terminal ,two breaking terminals and NON breaking terminal;
6.Two N lines are isolated by voltage transformer;
7.DC power supply or AC power supply;
8.Standard 485 communication interface with ModBus communication protocol,has remote control,remote communication,remote detection "three remote"function;or use front-end intelligent equipmentprotocol (YD/T 1363.3-2005)to remote detect cabinet status and to remote ATS switch on and off.;
9.Suitable for multiple wiring types (three phase four wire,single phase two wire,two phase three wire).
