[Electronics_101] Re: Outdoor Motion Sensor Activated Light - how to test?

 

Having repaired several units with failed triacs over the last 20 years with
a cheap but oversized replacement that then never fails, I fail to see that
your comment holds water...the higher voltage ones are far better, but
slightly larger, so they may not fit as a replacement of all units...

The cheap triacs that fail in Europe are usually for a max of 600VAC, there
are spikes on the mains here that exceeds that...

The Triacs that don't fail here are for 1000VAC or higher, the higher the
better but 1000VAC is good, I have never had one fail..and are still very
cheap. Cheaper than new sensors..and it's more fun to repair than replace...

Regards

Andy
