24 VDC 14.6A 350W Regulated Switching Power Supply
24 VDC 14.6A 350W Regulated Switching Power Supply is rated 4.1667 out of 5 by 6.
Rated 5 out of 5 by from 24v D.C. SupplyI'm using this in a combo production studio and HAM shack. This is a light weight, compact unit. I haven't tested it to the full load since I only need it to power a LCD monitor that draws about 6.5 amps and while the unit gets slightly warm with that load the on board fan hasn't needed to run. I haven't detected any RFI interference with my studio equipment or AM radio. You can buy this with full confidence that there will be no issues with electrical or mechanical noise.

Rated 2 out of 5 by from Good Supply but not cleanI bought this recently to run the 2x100 Watt audio amplifier. It does the job fine, but it emits bursts of 8 MHz RF at about 15 usec intervals. I tried to use my oscilloscope to look at the amplifier output and got this 8 MHz component.  I quickly tracked it back to the supply. This would not meet FCC requirements!

Rated 5 out of 5 by from Solid industrial grade supply......at an excellent price point for this sort of supply. The current model (the complaint you read in the reviews, above, was undoubtedly of an early model, in my humble opinion) has very good regulation when the attached amplifier(s) are driven pretty hard (meaning loud enough to wake the deaf, if not the dead). I have not done formal measurements, but the audio results at high load speak pretty well for this supply.Be aware that this model can be adjusted to deliver up to 28.5 VDC (albeit still at 350W). It is certainly capable of driving one of the 6 channel amp boards. I have experimented with building linear supplies for this class of amplifier; though I believe that a well regulated linear supply makes these boards (particularly the STM variants) sound a touch better, the difference, I feel, is not enough to justify the expense and trouble. (Powering one of the BIG boards (either the IR or the TI, which produce multiples of 150W RMS per board), is a different matter, since linear supplies for these boards work better, and in the case of the IR, cost much less than 2 50+VDC switching supplies. However, the biggies are for powering auditoriums, very large home theater setups, etc.--not your typical audiophile application.This supply works exactly as advertised, and is therefore, I believe, the preferred way to power class D amp boards of the mid power range (or a slew of low powered 24+VDC compatible boards).

Rated 5 out of 5 by from Two SureI have two Sure 4x100 amps hooked up to this power supply and it has worked great. It has a cooling fan, but I've never actually heard it run, because it doesn't get that hot. Being 14, I regularly give my home made 7.2 surround a heavy work out. The only trouble it has ever given me was when the negative wire that runs from the outlet to it slipped out.

Rated 3 out of 5 by from Maybe it good for their amps but not much else.This unit is a Mean-Well manufactured power supply but it is a old model that does not perform very well in high load situations. I used it to power 24 volt LED lighting and it had was not able to keep a 24 volt output, even at 50% duty. I replaced it with a new series of Mean-Well power supplies and everything works great now. My suggestion is that they might be good for the sure amps, but not for much else.

24 VDC 14.6A 350W Regulated Switching Power Supply

Building a portable boombox I can use around the house. Going to use this power supply with the 2x100 amp. Wanted FM as an option and wondered how I could connect a marine stereo unit (12V) to this power supply if at all possible.

Asked by: fuzzwah7
Not recommended. You should power the radio with a separate 12vdc supply.

I purchased this PSU to supply power to a Sure AA-AB33182 # 320-335 amp. May the 2nd of 3 V+\- sets be used to power a miniDSP2x4 which requires 4.5 to 24 VDC at the same time as the amp? Thank you

Asked by: ChrisKemper
Yes, as long as the output voltage is set no higher than 24 VDC.

I want to run the 100x4 amp. Will this psu pull the 14.6 amps all the time. Or just what the amp needs. I have a 20 amp fuse in my buiding. +other electronic things Will it trip. 

Asked by: Beanbo
This will only draw the current that the amplifier needs.

What gauge AC power cord should be used? would an 18 gauge be acceptable to use? 

Asked by: andysam
16 gauge is recommended for use with these power supplies. If the length of the cable run is only a few inches, 18 gauge will be fine.

Can this be used to charge to batteries in a series?

I am wanting to build a speaker project with one of the sure amps in it and run it off of two batteries connected in a series to get 24 volts. I Want to know if I could connect this directly to those batteries or if it would overcharge and ruin them or if anyone has any insight on how to do this...
Asked by: Mrgoodplayer
I am assuming you are using Lead Acid Batteries?Charging separate batteries in series requires much more circuitry than just hooking up a power supply, and can be dangerous if attempted. Voltage differences between the two and the large amount of current available from this ps will lead to gassing and various other nasty things.There are lot of things you can do though, but it all depends on your application.Do you want to use the amp while charging? I suggest finding a single 24 volt lead acid battery and 'smart' switching low noise charger.Don't mind charging between uses? Charge each battery separately or charge them in parallel with a 12 volt 'smart' charger.
