Paul_KD7HB:
Those relays are STAMPED with those values. DO NOT assume they are RATED and those values. Use a solid state relay with a heat sink.Paul
Hi paul.thank you for your replay and i will like to apologies for my not so appropriate replay to you earlier,i was a bit tired.
I was afraid that these small 5V ebay relays can't take that much punch (1500 Watts) for that long (15-20 hours/day).
What about this one
I know this is needs 12V to control it,but will this be able to carry my load and not melt?
About SSRs... If i understand correctly,they kind of "Pass current" even in they'r off state and they only way to stop this is by basicly connecting a light bulb "Before" the heater,so when the SSR is off,the lightbulb glows(takes care of the current that SSR passes in it's Off state).Because of this,I'm trying to avoid SSRs.
Are SSRs the only realiable way to switch big loads for long period of time?!
