*NEW! User-Friendly Transformers with Rotary Cam Switches!

With our new design we can offer a rotary cam switch with your transformer to eliminate connection headaches when attempting to use the transformer secondary as your primary. With one set of incoming and one set of outgoing Cam-Loks, you can now select your incoming power, whether it be 208V or 480V. You can also use the switch to turn the transformer off.
Imagine, no more turnarounds, adapters or confusion.

*NEW! Trailer-Mounted Transformer

APS Power Systems is now able to offer you a trailer-mounted transformer you can take down the road. Truly portable, this unit does highway speed or can be rolled around by hand.

The 15kVa encapsulated transformer gets it's power from a 50A 480V source, typically a welding receptacle. The 208/120V secondary provides power to the New 4x SS Panel where you will find the 15 or 20amp circuits and receptacles you need. Standard duplex, GFCI duplex or C1.1, Div.2 devices, these and others are available. The fused disconnect that can shut the trailer down is also NEMA 4X stainless steel.

The trailer has a hinged tongue that will drop out of the way which is good when storing it or if you have clearance issues. It is built to fit a 2" ball.

You will also find forklift pockets under the deck to allow you to lift it to another level or to move about a site.

This trailer is designed to be used in either the horizontal or vertical position.
