Relay FAQ
.The relay does not open
1) The load current is greater than the rated switching current of the SSR, which will cause the relay to short-circuit. In this case, an SSR with a larger rated current should be used.
2) Under the ambient temperature where the relay is located, if the heat dissipation is poor for the current it is subjected to, it will damage the output semiconductor device. At this time, a larger or more effective heat sink should be used.
3) The line voltage transient causes the output part of the SSR to break through. In this case, an SSR with a higher rated voltage should be used or an additional transient protection circuit should be provided.
4) The line voltage used is higher than the rated voltage of the SSR.
Application
Used in single-phase control system, when the power supply is abnomal.
