Detailed Product Description

JY-7 SERIES DK non-auxiliary power supply voltage Electronic Control Relay (JY-7A/31)

 

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.

 

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>>)
