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

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>>)
