Product Details

Astec 12V 24A 288W Regulated and Filtered Power Supply with Case and Accessories

Astec built this 12 VDC regulated and filtered power supply to output 288 watts continuously, and 400 watts peak for powering critical IBM storage servers. This power supply was then fitted to a durable steel case, in the USA, for use in many hobbyist applications: model railroads, slot car racing, power for amplifier boards, science experiments, and much more. It also works great in electronics labs as a reference bench top power supply.

Based on a world-compatible design, the power supply senses input voltage and works with 100 to 240 VAC mains power, 50/60 Hz, and consumes up to 700 watts of power during peak output. Active fault monitoring for short circuit and over-current conditions is built-in, protecting the power supply from failure. Not only is this power supply cULus recognized, it also meets TUV criteria for approval.

Power output is provided by two 1/4" thick binding posts, which are wired in parallel with the chassis mounted cigarette lighter socket. A coiled six foot, 2.5A fuse-protected cigarette lighter adapter with 2.1 x 5.5 mm right angle, center-negative plug (with power indication) is included for powering mobile accessories; a six foot 18/3 IEC power cable is also included.

Save over 30% off the original retail price of the power supply alone through this Parts Express exclusive buyout. Hurry, supplies are limited! If you need higher voltage, use the power supply with this DC to DC step-up voltage booster.

Note: This power supply has been internally tested at Parts Express to supply the advertised continuous and peak power ratings using an adjusted 320-3376, to step up the voltage to 50 VDC, for powering the 320-309 amplifier board, with reference level sine waves for signal input, and connected to two four ohm transducers wired in parallel for a 2 ohm load.

Specifications: • Input power: 100-240 VAC, 50/60 Hz • Maximum power consumption: 700 watts • Power output: 12 VDC, 24A (288 watts RMS continuous, 400 watts maximum instantaneous) • Dimensions: 14-1/2" L (including binding posts, 13-3/4" case only) x 6" W x 3-1/2" H.

Astec 12V 24A 288W Regulated and Filtered Power Supply with Case and Accessories
Astec 12V 24A 288W Regulated and Filtered Power Supply with Case and Accessories is rated 4.6 out of 5 by 5.
Rated 5 out of 5 by from Outstanding Value !!!I bought this to replace the failed power supply in my travel trailer. The factory supply is $350 and has less power output than this unit.Connected it up and the trailer is ready to use !!

Rated 5 out of 5 by from Nice unitI am using this power supply to power three MaxAir exhaust fans mounted on the roof of a 48 foot race trailer and 6 12 dc lights. The fans draw 5 amps at 12 dc each and the lights 4 amps total. Even with this unit lackinf its own internal cooling fan it does not heat up pushing 19 amps all day long. I am very pleased so far with the operation of this unit.

Rated 5 out of 5 by from Great power, even better price!I tested this 12 VDC power supply to drive a step-up voltage converter (part # 320-3376), to provide 50 VDC to a 2 x 300 watt amplifier (part # 320-309). One amplifier channel was then connected to two Aura Bass Shakers (part # 299-028) wired in parallel for a 2-ohm load.I was able to get about 28 VAC out of the amplifier for about 40 straight seconds (using a 40 Hz sine wave for signal) before the power supply went into protection; roughly 392 watts of output. It does everything it's supposed to and then some. Once protection reset, it came back on like a champ.Not only do you get a high current 12 VDC power supply for less than $70, you get a custom case for protection and large binding posts for connection. Two power supplies I tested were within 0.5% (yes, one-half of one percent) of the rated voltage out of the box, unloaded, and even under the heavy load of the above test condition.

Rated 5 out of 5 by from Power and then someTremendous unit for the price. Heavy duty connectors and in all a really well built unit

Rated 3 out of 5 by from ASTEC 12V 24A Regulated supplyPart number sold under is not the Astec part number, which is inside the black box. Someone has repackaged the supply. Astec thinks it was from a large vendor scrap out. But recovered and resold. There are no schematics available, nor any documentation with this supply from Parts Express. The supply puts out 11.9 V DC and seems like it can do 20 Amps plus. But if you need 13.8V DC it is not adjustable via any pot inside it, it would have to be done with changing the regulator ref voltage resistors. Makes a nice throw away supply for the price. Astec is a good name but there is no service for this unit.

Astec 12V 24A 288W Regulated and Filtered Power Supply with Case and Accessories

IS THE OUTPUT 12VDC @ UP TO 24 AMPS?

Asked by: greyghost45
Yes.
Answered by: MattP
Date published: 2014-04-15

Is the output adjustable (even if you have to disassemble)? Like TallBob1, I'm interested in powering devices that operate at 13.8 VDC.

Asked by: W9LS
I would assume you could but then you start messing with the internals of designed device and any warranty would be out the window. Would it not be easier to use a "pot" or rheostat on the o/p to decrease the voltage to your desired need?
Answered by: bigvette1
Date published: 2014-04-11

Is the output voltage really 12 volts or the 13.8 volts normally used on regulated power supplies that might be used on car/plane audio gear? Thank You ever so much P.E.

Asked by: TallBob1
The output on this power supply is regulated at 12 VDC, measured with no load at 12.05 VDC at the terminals.

Will this work as an LED driver for powering 12 volt LED lights such as Tuff LED lights used on cars and trucks?

Asked by: LEDLightBug
This will work to power any 12VDC device as long as it draws less than 24 amps.

How would this power supply work with the PE 4x100W TDA7498 Class-D Amplifier Board?  Would it also work with the 2x300W board.  The amperage is impressive current but not sure what impact 12v would have verse a higher voltage PS!?

Asked by: rmeinke
It says 14 volts minimum, but if it will even power on at 12 volts, you would only get about 10-20 watts at an 8 ohm load. To get any power out of it at 12 volts, you would need to run it at a 1 or 2 ohm load. If it will power on, it might work great with a 1 ohm load. But it does not say from what I can find.
