What are the requirements for the sensitivity of the power Relay to the component?:
1. Sensitivity of voltage excitation
At the most sensitive angle and 0.5 times the rated current, the minimum operating voltage of the power relay: rectifier type relay should be no more than 2V; static relay should be no more than 1V.
2. Sensitivity of current excitation
In the most sensitive angle and 0.1 times the rated voltage, the minimum operating current power relay (rated 1A relay, minimum operating current value should be reduced 5 times): Rectifier relay should not be greater than 0.5A; static relays should be less than 0.3A.
