Item: AMTEX Power Supply AC/DC 30VDC 55Amps - Rack Mounted

Location: Geelong/Melbourne

Price:   $220

Item Condition:  In good working condition with some external scratches.

Reason for selling: Not needed anymore

Payment Method: Pickup - Cash etc

Extra Info:  I have 4 of these power supplies sale. The power supplies are custom made by Amtex. The case is very solid and is only rack mountable, there is no feet for bench use but could easily be added. I opened one unit up and inside are two high quality robust switching power supplies linked together. However when I was trying to determine the individual units capabilities there was no markings to indicate a model or output volts amps etc on their own other than basic terminal markings. Please see pictures for more info.

 

Overall the sealed units specs are -

Input: 86-264 VAC

Output: 30 VDC @ 55Amps 

Power: 2000 Watts

Can I ask what you were using them for mate? 
Originally were used for operating solenoids.
My plan is to use them with Class D amplifier boards for amplification of 13 speakers for Dolby Atmos. I actually have 12 of these units but only require 7 of them.
With the dual power supplies and filter caps it's quiet a beefy rig. The steel enclosure is solid and well built.

The power supplies are actually 36v @ 28amp each. Digikey sells them new for $684 AUD! Might have to revise my listing when I get home I think and strip the Power Supplies out.61f470568fbb6797e00fd9eb6d882ee2.jpgcd3e7a225f13541be9989f7f30f019b8.jpg0eea6f92f17030d18f217fdb4956b8d9.jpg564e70bf118121c5b8f3adc4625df831.jpg
