Don't let the light touch the box. If you can touch the light it probaly won't set nothing on fire.can I hook up clf with cardboard box or is that a fire waitin to happen?
I got a 11VDC 350mA today, but they didn't have 12V .4AThat's what I would use until you could get one that is closer to .4 amps. The 500 mA may work, but I would worry it would burn it up. If you don't have much money in it and can get another on the cheap, go with the 500mA.
I got it wired and it's kicking out some good airflow thanksI think in that case you would want more amps (current). So let's see, 11v x .35mA=3.85 watts & 12v x .30mA=3.6watts. So that tells us the 11v should feed more current.
Please correct me if I am wrong fellow RIU'ers
NO they are different,it may work short term but I would not trust it.they use different ansi codes for each type of ballast (400w mh uses a m59 ballast & hps uses a S51 ballast) & each has different electrical characteristics. also the cap is differentSorry that this has probably been asked before but I've tried searching and can't find the answer.
I have heard that a MH ballast is just an HPS ballast without the ignitor. So does this mean I can take my 400W HPS ballast (which was an HPS you-wire ballast kit from my local electrical supply store) and cut the ignitor out of the circuit to use it with a metal halide bulb? (400W) Or even better, install a dual pole switch and make it a switchable ballast?
1400 watts would be OK but I assume you mean a couple different lights,I would put them on seperate timers & start them a minute or more apart. when a HPS ballast first fires,it draws double or more the rated current for a few milliseconds- not long enough to trip a breaker but if you are firing a 1000 and a 400 at the same time,it might overloadAlso, I want to run 1400W from a single 120V outlet on a 15A breaker with nothing else on that circuit. That is 12hrs a day at 77% of max load, is it safe? What about 1500W? which is 88%... I think too much for the sake of safety but what do you think? Thanks
I have a 120mm Comp radio shack fan.Thermaltake 120mm Fan (Black/Red)
Model: A2368 | Catalog #: 28-1108
Its says 6V/7V Max Started Voltage Rated Current .38A Power Input 4.56W
I wired it to a power supply that has an output of 4.5W and .4A
That will be the right match correct? the started Voltage threw me but it says max and i used 4.5W so I'm good right?
the transformers that say 12vac are not DC current so would not be my first pick,when it comes to the amps a transformer puts out, they list the max it can produce,it will only produce as much as is being drawn from it. if your fan draws .4 amps at 12vdc, you could use a transformer rated for 10 amps at 12vdc w/out a problem,in fact it would be better than using 1 rated at the .4 amps your fan draws because it would not be running at max output.I try to keep the draw to about 1/2 of what the transformer is rated for.The 6V/7V Max Started Voltage made me think i needed lower. I wanted the 12V for full power. I have a 12VAC 833mA : 12V DC 500mA : 12VAC 300mA
So the 12VAC 300mA would be the best one?
Thanks again in advance.
