Tech-condition
1 Environment temperature:-10℃~+50℃
2 Environment relative humidity:≤90%
3 Atmospheric pressure:80Kpa~110Kpa
4 Installed position:random
5 No explosive thing and corrosive gas around the applying place.The consistency of the
electric atomy can’t reduce the insulation level to less than the limit.
Main tech-parameters:
1 Current range 0.03A-0.999A, unit 0.001A;0.30A-9.99A,unit 0.01A;1A-30A, unit 0.1A (others by order)
2 Operate time 1.2 times modified value, operate time is less than 25mS
    2 times modified value, operate time is less than 20mS
3 Return coefficient 0.9~0.97
4 Error ≤2%
5 Power consumption ﹤4W.
6 Contact capacity
    250VAC COSФ=1.0 5A
    250VDC making 5A
    250VDC τ=5mS breaking 50W
7 Electrical life More than 105 times; Mechanical life More than 106 times .
8 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.
9 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
10 Anti-disturb capability Relay’s anti-disturb is accord with DL478-92 (<<Static Relay Protection and Security Auto-device
currency Tech>>)
