Our products have been used in every high-reliability application imaginable—from the nose cone of the Hellfire missile to the radar systems of U.S. submarines to space exploration. In fact, our products are used every day in the most demanding industries in the world, from oil drilling and alternative energy to aerospace, military, medical and telecommunications systems.

400hz Power Transformers

Our 400 Hz transformers offer maximum power with a flexible design—perfect for power and control applications. They are used chiefly in the power supplies of all types of equipment, including instrumentation, welding, test equipment, communications, and navigation systems.

• 400 Hz Miniature Power Transformer — offers the maximum power available in the smallest package size. It comes in power ratings from 0.5 VA – 40 VA, and in weights from 0.4 oz. – 5.8 oz. The parts can be ordered to the MIL-PRF-27 Qualified Products List part number, or as a COTS version of the military product. * See COTS version
• 400 Hz Power Transformer — a standard epoxy encapsulated transformer, designed for inputs of 120V, 400 Hz, and secondary voltages up to 300V. These parts can be provided in single phase or 3-phase with tapewound toroids, E or C cores, or laminations. The parts can be ordered to the MIL-PRF-27 Qualified Products List for Military Programs, or as a commercial COTS part.
• 400 Hz Hermetically Sealed Power Transformer — our 400 Hz transformers can also be ordered in a hermetically sealed version.
