Introduction

Congratulations on your purchase of the PSX-240 autotransformer. Please take time to read this basic instruction sheet covering common applications.

Basic Description

The PSX-240 is an autotransformer containing, in it’s raw form, two sets of windings in a 1:1 ratio.

Two 25 Amp AC breakers provide the input/output connection points for the unit. Below is the schematic for the internal wiring of the PSX-240

Configuration

Two basic configurations exist for the PSX-240 with the factory wiring arrangement.

1. 120VAC to 240VAC step up transformer
2. 240VAC to 120VAC step down/balancing transformer

Step-Up Transformer Configuration

In the step up transformer configuration, Hot leg L1 is connected to one of the 25A breakers on the PSX-240. 240VAC power is available across the two 25A breakers.

Step Down/Balancing Configuration

The step-down configuration for the PSX-240 is essentially the opposite of the step-up configuration. L1 and L2 (240VAC) power is applied to the 25A breakers of the PSX-240. 120VAC is then available from either L1 or L2 to system neutral. This configuration inherently provides balancing for the 240VAC source.

Mechanical Installation of the PSX-240

NOTICE! Please read and understand the IMPORTANT SAFETY INSTRUCTIONS section at the front of this manual for before proceeding.
The PSX240 may be installed on a vertical or horizontal surface utilizing the four mounting holes on the back of the unit with #10×2” screws.

AC Wiring Torque Specs

Torque specs for the 25A breakers are printed on the side of the breaker housing. The correct torque for the breakers is:

• 20 in-lbs

The torque for the screws in the neutral bus bar varies depending on the hole in which the wiring is installed. The larger of the two hole sizes in the neutral bar is the MAIN HOLE, the smaller holes are the TAP HOLES.
