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.

• 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

can a power distribution block be used to run multiple components off of one power supply?

Does anybody have any idea as to why the unit would power up, led and fan comes on, then units led dims down and also no output voltage, yet the fan stays running? This has happened on 2 units in a row.

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.
