Main technical data

Operating voltage: no more than 30-70% rated;Maintain current no more than 80% of rated current.
Action time: not less than 0.06 s (except DZS - 145).
Return time: DZS - 145 under the rated voltage, the current time is not less than 0.5 s, and then cut off power supply, relay the return time of not less than 0.8 s;Other relays return immediately after power is cut off.
Contact capacity: in voltage not over 250 v, current is not more than 5 a, time constant of 5 + 0.75 ms in dc circuit, the inductive load product output contact breaking capacity of 50 w.The output contact can reliably operate and return 5x10 times under the above specified load conditions.The output contact is allowed to be switched on for a long time with 5A.
Medium intensity: the product the conductive terminals together, for the leakage between the charged metal parts or shell, can bear 2000 v (RMS) of 50 hz ac voltage test lasted 1 minute without insulation breakdown or flashover phenomenon.
