Precaution:

  • For Load Current More Than 3Amp External Heat sink is Must.
  • Apply Heat sink Pest On the Base Plate of the SSR Before Mounting it on External Heat sink.
  • Fast Acting Fuse Require For Protection Of SSR.
  • SSR Rating Should Be More or Equal to Maximum Jerk Current of Load.
  • For Additional Transient Over Voltage Protection Add MOV.
  • Do Not Check SSR by Meter OR Continuity Tester. Otherwise, It will Always Shows OPEN.
