Static Bypass Switch

1. The statich shall consist of fully rated Silicon Controlled Rectifiers (SCRs) 2. The static bypass switch shall automatically transfer the critical load to bypass input supply without interruption after the logic senses one of the following conditions Inverter overload beyond rating. Battery runtime expired and bypass available. Inverter failure. Fatal error in control system. 3. The static bypass switch shall be equipped with a manual means of transferring the load to bypass and back to inverter. 4. Also UPS should have separate manual bypas switch
