Inductance Load
There will be a surging voltage (KV) when the inductance load switches between ON and OFF, especially for
the relay model. The methods to different power mode to absorb the surging voltage are shown below.
a. AC powerCR absorbing b. DC powerflywheel diode
Please do can’t use capacitance alone as absorbing as shown below.
Life of relay
The data of picture above is standard, but the life of relay is influenced by the temperature of operation
environmental.
The life is more than 100K times if the current is less than 2A.
