Description

• SQ8P Series Automatic transfer switch

  • Main-standby power supply, self-returning;

  • When any phase of the main power supply circuit fails (powe filure o phase lo , the switch is automaticly inputo the standby power supply ciouit which isusallythree-phase sampling, and the standby power supply is single-phase sampling;

  • When the main circuit returns to normal, the switch automatically switches back to the main power supply Loop.
