Hi guys and gals I’m trying to keep my grow room as quiet as possible. The only problem is when lights turn on and off you can hear the click of the furnas double pole contactor 110v coil. Can someone point me out to a quiet contactor.
I’m pulling around 500 - 550 watts @ 220v
Thanks happy growing

Forgive my ignorance but what does it do, is it for the lighting or the AC?
We don't have AC typically over here but we plug our lights into a contactor to stop the surge tripping the fuses or blowing the timers. Is that what your talking about? If so both mine came from hydro shops and don't make a sound, one can handle 2kw and cost about £10( its just a bulky plug with 1 socket and built in timer) the other can handle 3kw and has an extension attached for 4 plugs and cost about £25.
If I'm off track then ignore my comment, otherwise check out any hydro shop.

Yes is for 500 watts of cxb3590 @ 220v in my veg room and 1250 watts @ 220v in Flowering. The humming is not bad is just the coil. Every time is goes on and off you can hear the click really loud.

Thanks
 
This is the smaller one I use.

I only use this as before LEDs I used to use HPS and need it for the surge. I'm not even sure you get that surge on start up with meanwell drivers? I know people that grow with 400w of HPS that just use a standard segment timer for £5 and they don't blow when the HPS turns on, no contactor at all.

With the one I use you can only hear the timer turning and you would have to be right next to it with your ear on it to hear that.
Those above are 600w but mine says 2k on the back.

I also have this ,

No noise.
I'm sure there must be similar products in your part of the world.

Thanks for the help.
 
Thats one is is for 3 phase(will still work) and your looking for a single phase 2 pole 200-250vac rating with a control voltage of 110 vac, most will have a rating of 90-280vac. as long as your voltage fits between the minimal and maximum control voltage it will work.
what is the control (switching) voltage of that one?

Just so u know you will still have voltage present at your light, it just wont turn on until this relay energizes. If you want no voltage present you will need a 3 phase ssr or a double pole ssr. Ssr= solid state relay.

Can you point me out the right one plz? All I can find is 3 phase with 3-32 volt input.

Thanks
