Heavy duty power relay

Post by rygh »

I looked at the inrush current on my LED power supply - 40A.
And a lot of other LED/T5/MH setups are also very high at start-up, although
they rarely state the current.

That sort of thing will likely fry the current 10A relays over time.

It would be really nice to have one of the relay outputs be very high power.
Something like this:

Only $2 at allelectronics locally.

Or alternately, some sort of add-on relay that is high powered.

Another thing to consider would be a zero cross detector. That way you are only switching the relays during (or close to) the zero voltage portion of the AC cycle. This would also extend the life of the relays
