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.

Rated 5 out of 5 by from Great power supplyPower supply powers up my 100w mobile ham radio with no problem. I love this powesupply. Solid performer. Best money I've ever spent on power supply. My Fluke meter measured 11.99 volts but powers everything I throw at it.

Rated 4 out of 5 by from My test onn this 12 V systemI tested this unit with a brand new read volt meter it tested at 11.97 then put it under a 5.2 amp load over night tested in the morning unit ran cool and tested at 11.95 at the post !!!

Rated 5 out of 5 by from So far so goodI bought this supply to drive a bunch of 12v led display lights. I only needed like 9 amps but decided to go with this guy for added reduncancy and safety (and it was on sale). I plan on adding lights so now I can simply run another wire instead of buying a 2nd supply.

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.

Do you think this will this power a soundstream p2.400 amp?

Asked by: 876turtle

Can you use this by itself to power a subwoofer?

Asked by: andy3347
No, this is designed to power 12 volt devices. It could power a small 12 volt amplifier that in turn would power a subwoofer, but not the power supply itself. Please contact our tech support for more help with this question, or 800-338-0531 x1.

I am connecting a car amp in my garage to a subwoofer, (clarion apx2120) I'm wondering if the power supply enough to consistently power the amp. I have seen variations of different amperage ratings and not sure what to buy. Clarion has a 25amp fuse.

Asked by: james76
This should work fine for that application. Generally you want a power supply that has as much output capability as the fuse in the amp, but this shouldn't be a problem for normal conditions.

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: 2015-10-26

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.
