Default Intrest check - Kepco DC Power Supply - 48v 1500 watts

I recently got my hands on a big DC power suppy. It's a Kepco RCW 48-32k, rated for 32A at 48v. I'm not really sure what to do with it, or if it could be used as the power supply of an audio amplifier. I know the voltage is adjustable between 30 and 52 volts. Here's a link

The specs are:

* Wide range a-c input (85-264V a-c).
* 350W and 1500W (not 750W) models have current sharing for N+1 paralleling.
* Overcurrent limiter, square type.
* Undervoltage detector, (350W~1500W models) shuts down RCW if overload persists for more than 40 seconds.
* Overvoltage protector - immediate shutdown (reset by removing mains power for ‰ 40 seconds).
* Trimmable output voltage.
* Remote on/off logic.
* Alarm flags; OV, UV, thermal, fan (350W~1500W models).
* Power fail alarm (input power failure) (350W~1500W models).
* Output overvoltage and thermal protection indicator (red) (350W~1500W models).
* Output low voltage indication (red) (350W~1500W models).
* Fan alarm indication (red) (350W~1500W models).
* Remote error sensing: 0.15V for 3.3V models, 0.25V for 5.0V models, 0.4V for 12-48V models.
* UL/CSA/TÜV safety approval EN 60950.
* Certified per MIL STD 810E.
* DIN Rail mountable

The list price at Kepco is $1435.

Any ideas on what this is worth? Can it be used in a DIY amplifier project? I'm on the fence between selling it and buying a completed amplifier, or trying to build one.

For power amp you would normally use dual power supply. This appears to be single supply.
