Hi all,
I'm using a "big" 220V relays rated 10A with 3 contacts to switch a light DC load ON when line power goes off. 1 contact will fit my need, but they are available for about 3.5$ while the price of the 3 contact 220V relay I'm using is about 1$ only. Both are rated 6 to 10A. The load I'm using draws a current about 150mA or so... which make using such relays "odd" to use for operating them.
I'm building things using this load that should operate when AC power goes off.
So I think there should be a simpler way to do it.. maybe using a triac?
regards,
Hazim
