12v 30a Dc Universal Regulated Switching Power Supply 360w for CCTV, Computer Project, 3D Printer

This unit WILL push 400 watts but if your pushing it that hard use a small fan to blow on it to cool it down it will get warm when pushing over 350 watts.. it's slightly underrated at 360 as it will max out at 420 watts but it works REALLY hard to push 420 but pushed out 400 or less no problem so long as you use a small fan to Help cool it. It will put out 14.95 volts max at 27.1 amps for a total of 405 watts and with a extra small fan blowing on it not get to hot... Don't get me wrong pulling 400 watts from it will prolly shorten the life but I have 7 that are 3 years old with plenty of on time and they still work perfectly! I have 9 of them total three run in series making set to make 40 volts volts and 4 more run in parallel to make 120 amps.. to power my I charger Duo 410, then the other two run in parallel to power two icharger 306's at 14.5v 56 amps... This is FAR cheaper then buying a stand alone unit with that kinda power... They have held up very well and all I do is blow a small table fan on them when really pushing them hard and have had years of trouble free service when pushing them over spec. Some times when pushing them really hard with the 410 para charging 6 large 6s lipos at 70A they hold up no problem at all and get just a little warm with the desk fan blowing on them... To give you an idea if I used 14ga. Wire when charging like that it would melt the wires, 12ga. Wire will get so hot you can't touch it that's a crap load of power being taken in and pushed out and they handle it perfectly... Ide say on the 7 unit brick I built it has prolly close to if not over 800 to 1000 hours of run time on them while being worked way harder then most will work them with no problems... The two other units are never shut off and have been on now going on a year solid and no problems and I over watt the heck out of them at times with no Ill effects and seldom run a extra fan on them. These are the best value for the money out there, you can not get better quality for the money In a power supply anywhere.

These guys do the job and take a beating. Measued 9w at idle which was a bit surprising, but you probably aren't buying one to plug in and run with no load.

I like it's clean good looks and quality. I use this for a thermoelectric 9 bottle wine cooler that works on 12 volts. The old switching power supply running on 110V was damaged in a flood and I bought this to replace it. It does the job, makes no noise, and was easy to hook up. I suggest this product for any 110 or 220 V to 12 V DC application where it will not be accessible to kids or pets. Otherwise install it in an additional ventilated case. It made my $99 wine cooler useful again.

Purchased this to supply LED lighting strips used for under-cabinet workspace lighting. Total measured load is about 24 Amps, so the load fits nicely inside the this power supply's stated capability. Voltage is very stable.For my lighting project, the power supply lives in the bottom of a steel cabinet, in the space between the bottom of the cabinet shell and the inside floor of the cabinet. There's about 3/4" clearance above, and it's a non-ventilated space. I was initially concerned that heat buildup would be a problem, but that concern was unfounded in the end. The fan cycles on after about five minutes, runs for a minute or two, then turns off. Then a few minutes later, another minute or two of running and off again for a few minutes. Guesstimating that it's less than 50% duty cycle on that fan. Inside the cabinet, the fan noise is totally acceptable. Since it turns on and off again, even when the LED's are lit continuously, there's obviously plenty of excess thermal dissipation available, and no concern for overheating. After running all day, I can feel a little warm spot on the cabinet floor over the power supply, warm but not hot, so no concerns at all at this time.Construction of the unit is adequate for the duty. The connections are readily accessible under a flip-up cover, with incoming line connections at one end of a screw-terminal barrier strip, and three pairs of DC connections at the other end. The screws easily accepted 12ga solid conductor for the incoming AC, and doubled-up 16 gauge stranded wire for the DC load side connections. I added external fusing on the DC side for each of the four LED loads, using automotive fuses and holders.Overall I'm impressed with the quality, size, and capacity of this unit. I have another work area to light up the same way, and will be buying another of these power supplies to power that section the same as the first was done.Other reviewers have commented on the lack of primary circuit protection, and the lack of an on-off switch. Users should be aware that this power supply is not something that should be installed where it is exposed, because of the way the wiring is connected. It's more of a component in a system, meant to be included in your enclosure. With that in mind, supply-side switching and primary over-current protection for the AC line side must be managed externally. Load-side over-current protection is managed with thermal overloads, but that's protection for the device itself, not for your secondary wiring. For those you'll want fuses or thermal breakers sufficient to protect your DC wiring.For this duty, I can highly recommend this power supply.

Bought this use as my source of 12vdc shore power in my Skoolie.Currently using it to power my water pump, vent fan, diesel heater and led lighting.The supply is compact and easy to connect to. I like the fact that it has an adjustment for the actual voltage output so you can increase it to help fight voltage drop on long runs. I have yet to draw enough current to activate the fan so I can't speak on how quiet that part is.As of now I am satisfied with it's performance. If that changes I will update.

Quiet and compact. Just what I needed.

Suddenly my CR10 bed was taking forever to heat up and was maxing out at 50C. The printer would print and then part way into the print it would get a Printer Haulted with either a Bed thermal runaway for heating failed message. My Mosfet was hitting over 140C and I measured PSU voltage at 8.6v volts idle or printing. I am shocked the printer would function and even print with only 8.6v.As soon as I replaced the power supply, 12.6 volts idle and running. Bed heats up to 60C in less than 5 mins. And mosfet maxes at around 40C during bed heating and then drops lower while maintaining heating. After a few days of printing I can confirm everything works great again with just this power supply replacement.The CR10 included power supply lasted over 3 years. I hope this one lasts as long too.

Love it!

Da la capacidad indicada y mantiene el voltaje estable

Works flawlessly! Great product, have it on my Anet A8 3d Pinter. Easy set up and stays cool with the built in fan.Thanks,Jeff

Im no electrician just 3d printing hobbyisti bought this based on a few videos recommending this but it was US amazon and or not available also im in australia so using amazon au makes more sense anyway. so i got it to replace the power supply that came with anet a8 which shorted after a year and a bit with small pop crack and died, motors and board seems fine so it was just the psu.so i did switch to 240v and screwed in the leads properly according to my old power supply. it worked for maybe 5 short prints spanning through out the week, eg 5 minutes 1 print 3 hours large prints in PLA settings so fairly low temps which i assume doesnt suck up a lot of power but i digress. spanned at most 24 hour life span of this power supply. it shorted similar to the old psu but with a louder pop crack and even switched the breaker for upstairs.i honestly have no clue why it happened, i switched to 240v because au is 240v, i screwed the leads positives and negatives, and the power cord postitive and ground/negative. so a 2 and half to 3 week wait for this to arrive just for it to pop is quite unfortunate.

Excelente para mi impresora anet a8 , viene con su ventilador y mi impresora trabaja sin problema.

work well but for the anet a8 bolt pattern dont fit well
