1、All relays are shipped in the “closed”position.It is possible that during transit or final assembly the relay could change its state to the “open”position.
Therefore,it is recommended that all relays be set to the desired state of the relay via a power supply.
2、In order to maintain an “open” or “closed” state of the relay,the coil voltage should reach the rated voltage. The pulse width should be 5 times the operating time to ensure a proper change of state.Do not energize both T1 and T2 at the same time on a dual coil or energize the coil for longer than 1 minute (damage to the coil could incur).
3、Relays have polarity,if the user’s need different from information,shoud be contact us.
4、The relay to the factory inspection and use should handle to prevent damage effect，to the factory for damaging the goods shoud be strict distinction between the normal product and must not uses.
All con tact current marked on Relay and the catalogue are resistive load, if not specified.
Under rated switching voltage, the inductanee load should not exceed 30%, motor load should not exceed 20%, light load should not exceed 10%, capacitive load should not exceed 5% of rated resistive load.
We recommend to choose contact load current not exceeding 60-70% of the steady state current in view of reliability.
Please refer to below table for in-rush current at different loads:
|Load type||Resistive||Sodium lamp||Mercury lamp||Inductive||Motor||Transformer||Incandescent||Capacitive|
|In-rush||1 time||1-3 times||3 times||3-5||5-10||5-15 times||5-15 times||20-40|
