Electrocube, design manufacturer of electronic components

Transformer Rectifier Units (TRUs)

Custom designed and built, single/multi-phase electrical signal

Custom Transformer Rectifier Units (TRUs) designed and manufactured by Electrocube represent its most recent product expansion and one of the few component manufacturers in the United States.

Custom Built

TRUs are designed in-house at Electrocube's facility in California, TRUs utilize lightweight, high reliability foil transformers to produce a unique power supply. The key differentiator of the TRU is the ability to “multi-phase” or pulse the signal. These features allow the reduction of the output EMI Filter, eliminating excess weight and size.

Since TRUs are custom built and not off-the-shelf, allow six to 18 months for R&D design, quote, and prototype.
