Single Phase Voltage Protector Real-time Protection And Over-voltage/Under-voltage Protection For Single Phase Power

RJ-FV220 single phase over / under voltage protector is an embedded relay protection product developed and manufactured by our company, the product has the function of over voltage protection and under voltage protection. It is a multi-functional protection product suitable for all single-phase power supply.

RJ-FV220 single phase over / under voltage protector is designed with embedded system, which has the advantages of small size, light weight, strong shock resistance and shock resistance, high reliability, long service life and convenient installation. The internal electronic components are all imported industrial grade products, stable performance, can adapt to any complex working environment.

Product picture

Product size and weight
Dimension: 50*50*25mm(L*W*H)
Mounting hole position: 40*40mm(L*W)
Aperture: 4.3mm(*4)
Surface treatment: Double coated with three proofing paint
Weight: 60g

Product function
The over voltage protection voltage is 265v, the protection time is 10 seconds. The voltage recovery value is 255v.
The under voltage protection voltage is 175v, the protection time is also 10 seconds. But when the voltage is lower than 175-15 = 160v, it will be judged to be the loss of power state, and the protection time is 2.5s. The voltage recovery value is 185v.
After entering the protection state, when the voltage is restored to normal, the time is greater than 30 seconds, the protector returns to its normal state, and the contact of the relay will be closed.
The shortest time interval of the two closing of the relay is 3 minutes

Indicating lamp introduction
D6 is the running status indicator, green.
When the D6 is always bright, it indicates the normal state of the protector output, and the contact of the relay is closed; when the D6 is not lighted, the protector enters the protection state and the contact of the relay is broken off.
When the D6 flashes at 1.2 seconds at a time, it is under voltage or over voltage state. When the D6 flashes at 0.3 second at a time, it is loss of power state. When the D6 flashes at 2.4 seconds at a time, it is state of the protection will be released.
D7 is power indicator, red, will light up when power up.

250# copper insert introduction
Power Supply: JP1,JP2
JP1 connected to L, JP2 connected to N, power supply range is AC130v~AC275v, 50Hz.
Digital output; JP3,JP4
JP3 and JP4 are normally open contacts of the relay, and the load current is 3A, which is conducted in normal state and disconnected when no power supply and protective state.

Relevant international and national standards
This product complies with GB/T 14048.1-2000,GB14048.5-2008,IEC60947-1:1999
