Avoid redesign - Use Triad HS and HSM transformers in military prototypes

Triad HS and HSM series transformers are designed to meet MIL-T-27 requirements. Most of these transformers use standard MIL-T-27 case sizes. Exceptions are GP cases or any cases showing a Bw dimension, which may be classified as MIL-T-27 'YY' cases. Equipment using these transformers need not be redesigned to submit for military approval. The basically good design factors which are necessary to meet MIL-T-27 standards for performance ensure longest life in any class of service.

These transformers are permanently marked with electrical and test data as specified in MIL-T-27. All are "Climatite" treated, use sturdy TRIAD terminals and are beautifully finished in gray enamel.
