What is a DC Surge Protective Device?
DC Surge Protective Devices (SPD) are essential for safeguarding electronic systems from voltage spikes, ensuring both reliability and efficiency. Their ability to absorb and redirect excess voltage helps ...

• 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.
