AC Power Failure Alarm Power outage Power cut sensor Aquarium power failure detection 220v/380v three-phase

AC Power Failure Alarm Power outage Power cut sensor Aquarium power failure detection 220v/380v three-phase alarm controller

Single-phase/three-phase dual purpose    
 Power failure detection    
 Lack of phase detection    
Indicator light reminder    
Relay output    

The power-off sensor will output N/O and N/C switching value signal, when any phase is power off from the phase A, phase B and phase C of the three-phase AC, or the municipal power grid is power off.
It is suitable for kinds of industries, such as communication room, hospital, power supply, the customs, banks, government, factories and so on.
It can advice the alarm of power-on and power-off through customized smart phone or GSM message.
1. Alarm mode: when phase A, phase B and phase C in the three-phase AC power or 220v power grid are monitored by the power-off sensor, any phase is power off, the sensor will output the N/O and N/C switching value signal.
2. Monitoring voltage: AC380v + 20%, AC220v + 20%, 380v three-phase three-wire system (customized).
3. High voltage isolation: the insulation voltage of the detector and trigger is greater than 1500v.
4. Flame-retardant and explosion-proof: made of semiconductor contactless switch element, it will never appear the spark phenomenon when it is on and off. So it can be used in flame retardant and explosion-proof occasions.
5. Safe and reliable: there is no heating element. It will not occur temperature rising phenomenon when long-term high temperature and high voltage operation. The shell will not become hot when touching by hands.
6. Working environment: temperature-30 ? ~ + 90 ?, relative humidity = 90% RH.
7. Volume: 86*36*58 mm.
