Industrial Test Transformers

 
In industrial manufacturing, the job is not done until the product passes the test. Global manufacturers of items such as pumps, drives, and generators build products for use in many different electrical systems, which requires testing of operation at both 50 and 60 Hz and a multitude of voltage combinations.

A configurable transformer is an essential component of their test lab. High reliability means less factory downtime and reduces revenue losses due to downtime.

Each manufacturer will have unique requirements. PCT’s engineering team will work closely with you to determine the voltages, phasing, and switching capability you need to provide the Right Transformer for the job.
