Three, technical requirements
1, rated: rated voltage DC/AC110V, 220V.
2, action value: action DC voltage should be not greater than 70% of rated voltage, AC rated voltage should be not greater than 75%;
3, return value: return voltage should not be less than 10% rated voltage.
4, the action time and return time is not 15ms.
5, contact capacity: no more than 250V voltage current less than 1a, the time constant for 5ms DC + 0.75ms have sense circuit load, the breaking capacity is 50W.
When the voltage is less than 250V, the current is less than 5A, the power factor of AC circuit COS with =0.4 + 0.1, breaking capacity for 500VA. Output contacts in the above provisions
Under the load condition, the product can act reliably and return 5 x 104 times. The output contact allows for a long time 5A.
6, power consumption: at the rated voltage of no more than 5W/5VA.
7, withstanding voltage and insulation: all circuits of the relay on the shell and non electrical metal parts, and electrical connection between the circuit tolerance 50Hz AC voltage 2KV duration
1 minute test without breakdown.
