The ATS-125A-RSC transfer switch is designed to automatically transfer load circuits from the main power source to the backup one in a wide range of 1-3 phase applications.
FEATURES
– electric motor gear shifting;- 1-3 phases 4 poles;- Automatic and manual/remote mode selector;- 3-position switch handle (“I”-”0”-”II”);- Remote control outputs for generator start/stop;- Remote control inputs for external ATS/AMF controller;- High reliability and low energy consumption due to fixed positions of the switching mechanism, supplied only during the switching process;- Position indicator on the front side and external lamp outputs;- Safety fuses for the control signal;- Built-in mechanical and electrical interlock.
INPUTS AND OUTPUTS
– Normal output inputs: R, S, T, N;- Backup source inputs: R, S, T, N;- Load loop outputs: R, S, T, N;- External indicator lamp outputs;- Remote generator start/stop outputs;- Remote ATS/AMF external controller inputs.
