TM Series Introduction

This transformer series is designed specifically for 400 Hz operation. This series offer more watts per size and weight than conventional power transformers while providing excellent regulation and low leakage inductance. The entire series is available in molded and open constructions. These power toroid transformers are ideal for airborne, space, missile, and industrial applications where small size and dependability are required.
