Turning on the power?

post #1 of 7
Thread Starter 
quick question for those powering pelts with dedicated meanwells.


how are you switching the psu? relay? power switch?

I'm trying to find a switch that will be able to handle the load of a tec but afterlooking at some higher end industrial grade switches seems even the current stock of marketed switches can only do 15-30 amps at 125 volts ac.

the manual for the pump i'm gonna be using suggests i use a switch after the psu (between the pump) in order to switch. (its using a smaller sized meanwell as well)

I'd like to do this with the tec's as too:

Turn on the pump, switch on the pelts--> turn on the comp.


Anybody?


Edit: K, i found what i was looking for. I'm gonna switch the psu from the ac side instead of the dc side as recommended by iwaki.

Thanks for the help everyone.

This isn't what you need but I thought you might have a use for one..It's modded with an AC filter in it...Pump Relay Switch Kit v3

yes, i seen that one

though i would need something rougly 2x the amp carrying capabilities.


There's probably a manufacter out there that has an appropriate switch or relay that can handle such a load.


thanks.

Edit: Seems frinding a DC toggle switch able to handle a higher load is very difficult to find in manufactured sales.

a relay will have to be it though, how the **** do the relay even switch and maintain the power?

Relays recieve power from the main PSU... say 12v. This powers a magnet which then moves a little bar. This little bar then completes the circuit for the Meanwell PSU. As long as the relay recieves power from the main PSU, the magnet holds the switch in place. Remember when looking at switches and relays... most are rated in AC, not DC. Also, make sure to get the correct relay rating 12v or 5v. They use a tiny amount of current so they will not impact your main PSU.




If the PSU is for the TEC only, you want to power on the PSU with the switch. Better than just turning on the TEC since the PSU will just be idle all the time otherwise.
Once again...

You people and your fancy solutions

Get a power strip; hook everything up to your power strip; turn your power strip on before powering up the computer

EDIT: You could even go as far as cutting the green/black cables off the ATX connector to auto start the PSU when you power the strip, put the power strip inside your comp, cut out the power switch and run some extension wires to your power button. This would power up the power strip when you hit the power button on the computer and start anything hooked up to it. Obviously if you want delay times on bootup / shutdown this wouldn't work but so far I haven't had any reason why I would need to do delay timings. The only reasoning I can see for delay timing is if your water loop gets so freakin hot it's in danger of damaging the CPU once the pelt is turned off as the heat will bleed through the block once this happens.

... i was actually wanting to have something of those guys at the power plant:

worker 1: "we have voltage drop across reactor one"
worder 2: "probably charlie running his christmas lights again, Turn on reactor 2"

worker one flips gigantic switch

*Kachunk, CLICK!

worker 3: "We have auxilary power routed begin capacitor overvolt charge"
worker 1: "Hurry she's gonna blow Captain!!!"

worker 2 lights up a cigarette

worker 3 switches three toggle switches ala submarine movies saving the day with toggle goodness.
