What matters should be paid attention to in electromagnetic relay operation?:
1, the action voltage is not greater than 70% of the rated voltage.
2, return voltage is not less than 5% of the rated voltage.
3, the relay action time is not greater than 60ms.
4, the power consumption under rated voltage is not greater than 4kW.
5, thermal performance, when the ambient temperature is 40 degrees, the relay coil long-term withstand 110% rated voltage, the temperature rise is not more than 65 degrees centigrade.
6, dielectric strength
The relay circuit connected between the conductive and non electrical metal parts and shell together with the exposed coil circuit and contact circuit, should be able to withstand 1kV (RMS), AC test voltage, 50Hz duration 1min, without insulation breakdown or flashover phenomenon.
7, contact capacity: sense in the DC loop (=5ms), U = 250V, I = 2A, 20W; (COS =0.4) in the AC circuit, U = 250V, I = 2A, 80VA.
8. The relay life is 5 * 10 times. The relay has a mechanical life of 10 times.
9 and weighs about 0.8kg.
