Product Details

48 VDC 12.5A 600W Regulated Power Supply

Large amplifiers require large power supplies, and they don't get much larger than this! With a regulated output of 48 Volts DC (which can be adjusted from 43 to 56 VDC), and current capacity of 12.5 amps, this power supply is the perfect partner for amplifier boards capable of up to 600 watts of output.

Voltage input can be switched for use with 110 or 240 VAC mains power. Overload, over voltage, and over temperature protection is built-in, shutting down the power supply to prevent damage and then restoring power upon recovery. Forced air cooling regulates temperature internally. Power supply cable and output cable included. UL recongnized design.

Note: Minimum recommend power wire gauge is 16 AWG.

Specifications:
• Input power: Switchable between 90-132 VAC and 180-264 VAC, 47-63 Hz
• Current consumption: 12A @ 115 VAC, 7.5A @ 230 VAC
• Output power: 48 VDC, 12.5A
• Adjustable output voltage range: 43-56 VDC
• Efficiency: 88%
• Dimensions: 9.7" L x 5" W x 2.5" H

48 VDC 12.5A 600W Regulated Power Supply
48 VDC 12.5A 600W Regulated Power Supply is rated 4.0 out of 5 by 2.
Rated 4 out of 5 by from Does Exactly what it Needs to DoThe fan kicks in immediately and does a great job at keeping this power supply cool. The only reason I'm not giving this five stars is because the voltage adjuster is rather delicate and you need to make sure you're gentle when adjusting the voltage so that you don't end up pushing it in. Besides that I'm happy with this purchase because it powers my 600 watt amp with ease.

Rated 4 out of 5 by from Works great, but the fan is loud....As always Mean Well PS are quality products. This seemed to be the obvious match for my 2 X 300 Watt 4 Ohm Class D Audio Amplifier Board - TAS5630 300W Stereo Power Amp. My only complaint is the sound of the fan is pretty loud even when cold with no load attached. I had really hoped for a quieter thermostaticaly controlled fan that would only really be noticieable under load, at which point the music would normally mask the sound. I will try mounting this in the back at the bottom of my stereo cabinet and see if it's still a problem.

48 VDC 12.5A 600W Regulated Power Supply

Would there be any way to use a 12v trigger with this power supply?

Asked by:
Unfortunately you would need to build a full relayed circuit with this power supply in order to use a triggered input.

Possible to do remote turn on/off

Is it possible to hook up a remote turn on/off to this power supply? If so, how?
Asked by: 12vaudio
Unfortunately this does not have any kind of trigger or remote turn on feature like an automotive amplifier. The only way would be an in line switch on the power cord.

Can you hook up (2) of those in parallel?

I'm looking to build 2x250W IRS2092 based Class-D amplifier (p.n. 320-313# and trying to achieve the lowest distortion possible at 4 Ohm using B-G RD50 Planar Transducer. I would like the power supply to cover the worst case peak current of 16A #8A per channel; 250W/ch; Re=4Ohm# and still have some headroom left over.Is it possible to connect #2# of those power supplies in parallel to double the current capacity? I that case I'll need #4) power supplies total. I'll be isolating the metal cases from one another.Thanks,Will
Asked by: WillP
You may well be able to parallel two of these supplies but you'll have to use some isolation diodes between them to keep the two supplies from looking like loads to each other. Here's what I mean. Some types of switching power supplies are sensitive to what they see on their output as they "start up". Also, some supplies start up a little faster than others. At times, the slower supply might interpret the voltage that just showed up on its output terminals (from the faster supply) as an overload condition, causing the supply's internal protection to shut the supply down. Thus, it never starts. Adding the isolation diodes (I use a big full wave bridge mounted on a heatsink) allows both supplies to start normally. Well, it should, anyway. With this kind of voltage and current available, proceed cautiously. You don't want to smoke anything. You may also want to add a load resistor across the output to draw 50 milliAmps or so. This lets the output of the supply "see" a ground reference and helps with stability. I don't guarantee this will work with this particular supply, but I've used it successfully in the past, so it's worth a try.

Can you put a step-down transformer on the output?....

...To lower the voltage to a usable level with the sure 6x100w Class-D Amplifier board, or would the added Inductance mess with the clean output?and yes I know there'd be power loss. Ohm law.... really important ;)
Asked by: Wolf Punch
Unfortunately this is not possible because this is a switching power supply.

car amp ?

i was wondering if this could be used to power a car amp in the house ?
Asked by: hiviman
No, it could not. Car amps run on 12V, whereas this power supply outputs 43 - 56V (user-adjustable). You'll need to find a power supply that outputs 12V, and which can handle as much current as your car amp requires.

My question is actually, how the voltage is given. Both the amps and the powrsupply state a rating, but what is really importan is the way it is given

The power supply states it 48VDC and up a bit, but is this rating across the supply or is it +/- 48V center tapped. Not all equipment use center tap and then if this is +/- 24V it makes huge difference.I noticed that these amps can go from 14 - 39 VDC so if the supply is +/- 24 it will work, but not to give the amps their full power as it is likely by the specs that it would require around 36V. Now that makes also a big difference for what you are expecting.Also the amplifiers are 36VDC. Is this +/- 36VDC and is this the maximum voltage, in which case this power supply if it is +/- 48VDC much too big. For some reason I've noticed that power supply voltages don't mach lots of DIY amplifiers. Like they tend to be low or high. This supply would be good for amps requiring +/- 48 - 60 VDC. The important thing as I mentioned is to mention the way voltage is give and if unit is center tapped. Even if it is most likely that modern high power amps are + ground - it might not be clear all the builders and somebody might have old transformer around that provides 35 and up voltage without center tap and might think that it would work. Also in this add page it would be good to make sure that power supply doesn't burn the amp because the high voltage as it is obviously meant for these amplifiers at least the way it is on the page.As you can see there is quite a difference on the way information is given and it can cause disappointments number of way to customers me including because I have been looking for a easy to setup system and at the moment the power supply is my biggest need and that somewhere +/- 40 - 60 VDC 300 - 600W
Asked by: PasiPT
There is no center tap. This power supply is 43-56 VDC from ground to positive voltage. None of the power supplies or class-D amp boards sold here use a negative voltage. This power supply can be adjusted to the max 56 VDC to run 320-313 amplifier, which requires 55-65 VDC.
