Product Details

High power 5W Power consumption VOLTAGE Electronic Control Relay (JY-7A/12)

 

Main tech-parameters:

1 Modifiable range of voltage     10V-399V  

2 Power consumption    The most power consumption is less than 5W.

3 Operate time  Over-voltage relay: 1.2 times modified value’s operating time is less than 25ms 

  Operate time of two times modified value is less than 20ms.

4 Resetting time  over-voltage relay resetting time is less than 27ms

5 Resetting ratio  over voltage relay resetting ratio0.93~0.97

6 modification errors  Range of rating is 15V to the limit. modified errors is 

less than 2%. At the limited temperature,  errors of any modified value above 15V is less than 3%. 

7 Contact capacity

    Relay output circuit contact can break the voltage less than 250V,  50W for 

the DC inductance charge circuit which time constant is 5±0.75ms. In the AC 

circuit which voltage is less than 250V it is 250VA(power factor cosΦ is 0.4±0.1). 

Relay’s contact can make 5A for long life.

8 Electrical life   More than 105 times

9 Mechanical life  More than 106 times .

10 Medium intensity

Relay’s every electric terminals are connected together. And it can endure a 

2000V and 50Hz AC voltage(virtual value) to the non-electrification metallic 

outside part or shell. There is no insulated breakdown or flashover phenomenon.

11 Insulation resistance  

    Relay’s every electric terminals are connected together. To the non-

electrification metallic outside part or shell,  its insulated resistance is less 

than 300MΩ measured by tramegger with  opening voltage is 500V.

12 Working condition : Temperature -10℃~+50℃, relative humidity≤90%,  alti-tude≤2000m

13 Anti-disturb capability  Relay’s anti-disturb is accord with DL478-92 (<<Static Relay Protection and 

Security Auto-device currency Tech>>)

 

Description

 

 

JY-7 series type DK non-auxiliary power supply voltage relay is used in
relay protection devices of electromotor transformer and transporting and
transforming power. And as an over-voltage protect or low-voltage closedown
startup component.
