What is this

[d00m1ord]

So my new job wants me to go through our stock room and get rid of stuff we dont use or need and i found this and i cannot find anything to tell me what it is or what it does. Anyone know?

At a quick glance, it looks to be an electronic load for load-testing.

Looks like it's a device to test power supplies:

The Froment Proofloader is a load bank system that is used to test power supplies from 1kW to many MVA. An extensive range of resistive, inductive or capacitive load banks is available that can be customised to meet the requirements for testing generating sets, uninterruptible power supplies (UPS), aircraft ground power units and battery systems.

I don't speak technical though, so not sure if this device is still relevant

 

Looks like this company (Froment) is part of 'ASCO Load Banks' now.

This is what's called an artificial load, you use it to test a power source in place of the real thing it will be powering. It looks like it's an AC load as you can change it from Y to Delta configuration (three phase power).

 

Generally these are used to test the power source's efficiency under lots of different conditions or its safety feature if it does any kind of voltage or current limiting. Let's say you wanted to test a power source for a wide range of motors, you could configure this device to appear like several different powered motors for testing.
