AC 220V Power Failure Detector

1. Alarm method: When the sensor detects a power failure in the power grid, it will output a normally open and normally closed switching signal to implement a power outage alarm function.

2. High voltage isolation: The insulation voltage between the detection end and the trigger end is greater than 1500V.

3. Flame-retardant and explosion-proof: Made of semiconductor non-contact switching elements, there will be no sparks like relay switches when the switch is on and off. It can be used in flame-retardant and explosion-proof situations.

4. Safe and reliable: There is no heating element, and there will be no temperature rise when working at high temperatures and high voltages for a long time, and there will be no dangerous phenomenon like the shell of a relay switch being hot to the touch.

Mains power and UPS power supply are particularly important in computer room. The data of allservers and network equipment will be lost as long as the power supply is off, so it is very important to detect whether the AC power supply in computer room is off. SP220 AC power failure detector can be used at lot of applications where need power failure monitoring. It's installed in the power supply and distribution box or at the output end of the UPS to monitor AC power outage or not.
