Vanguard Announces ATRU Series of Increased Efficiency, Space-Saving Auto Transformers

Vanguard Electronics Vanguard Electronics, under the iNRCORE Family of Brands, is launching a new line of space saving power converters, the Auto Transformer Rectifier Unit, or ATRU series. The line ranges from units with 2 kW to 10 kW power ratings and includes the TRU-12-2, TRU-12-5, TRU-18-5, TRU-18-10, TRU-30-5, and TRU-30-10 models.

“There is an ever-growing and evolving need for smaller and lighter high-power electronics for current and future generations of aircraft and high energy systems. The ATRU Series meets those needs and represents a paradigm shift across all commercial and military applications. We coupled our high reliability design capability with our unique approach to high power magnetics to solve an industry need for higher efficiency, space-saving technology today and set a path toward the solutions of tomorrow.”

Ideal for the military applications and avionics where space and weight are at a premium, the Vanguard Electronics ATRU series of increased efficiency transformers was created to achieve size and weight reductions while maintaining an efficiency rating of above 95% and low harmonic distortion (<3%) throughout the design. Individual ATRU models operate at 12, 18, and 30 pulses. Each is designed to operate in extreme environments, capable of being stored in temperatures between -60° Celsius and +135° Celsius while operating in temperatures between -55° Celsius to +130° Celsius.

Common applications include naval electronics, airborne electronics, military and commercial aircraft, avionic flight controls, and radar and sensor mechanisms.
