Ganoderma said:your coil is 110v. you can use yours as 120v or 240v, if you use it for 120v ballasts you can use the one relay for two ballasts.
the coil is what you'll wire your timer to, and that flips the ballast to the other bulb
DB2004 said:Actually you shouldn't use one of those relays for two ballasts, 4 lamps. You'd only be switching the hots and the common wires would be connected. That is not a good idea. You should only use one relay per ballast and two lamps. Switch both the hot and the common wires on both lamps.

germination said:hey, everybody, and professionals!
I'm write from Hungary, so excuse my english. I read all the topic, and i want to make a simple flip-flop system,first with a 150watt Hps. My big problem is the relay. I really don't know the right type. I found a website in Hungary with many relay, but i can't choose. please help me. This site is international so you can help me, and I can buy. please choose one for me.
my theory: 2 lamp with one ballast. (Here 240v the official, but i think it's not important.) So 240v from the wall ---- ballast (150watt 1,8A) ---- relay and of course timer (12/12, 7/24) ---- 2 lamp by turns. Thats it!!
If somebody can help me please don't hesitate, please choose one relay for me!
Thanks fwd.... Germination!
DB2004 said:From what I've seen, too many people are building flip/flops with the wrong relays that are not capable of handling the voltage spike and constant voltage powering the lamp. I also see people using copper wire rated at 300 volts. This wire is meant for residentail wiring and has a maximum rating of 300 volts, not 600 volts. Before you attempt to build any device that requires high voltages, be very sure you know what you're doing. I custom build flip/flops, timers, load centers, controllers, thermal shutdowns for any application. PM me here or send an email to [email protected].
