General
WCQ2 series double power supplies automatic transfer switch (ATS) applies to AC50Hz, rated operation voltage 400V, rated operation current 16A to 2000A, to two circuits power supply of emergency power supply system. It can be set as manual of the mutual transfer between frequent-use and backup power supply, as circuit controlling switch of control, signal, and interlock functions. Some types of the product have communication ports to make it realisable of remote control and unattended substation to the user. It applies to residence community, hospital, mall, airport, etc.,
The ATS meets standards IEC/EN60947 and GB/T14048.11.
