Inwood, NY — Signal Transformer, a subsidiary of Bel Fuse Inc. has introduced its SHE (Super High Efficiency) Series of chassis-mount power isolation transformers boasting 97.5 percent (min.) efficiency. The transformers have been specifically designed to address the electronics industry's growing demand for parts engineered to reduce power consumption without sacrificing overall system performance.

The SHE Series is the latest addition to the company's extensive portfolio of standard and custom power transformers for worldwide applications. The seven-part series incorporates a UL 1446 Recognized Class H, 180° electrical insulation system, and is design-compliant with UL 506/UL 5085, CSA C22, VDE 0805/VDE 0550 and IEC/EN 61558-1.

The transformers offer continuous power handling from 250VA to 2500VA, and have a 4000V rms isolation between the primary and secondaries. Moreover, their winding configuration allows engineers enhanced design flexibility as the same part can be used in 115V or 230V applications.

The Super High Efficiency transformers utilize optimal quality core and conductor materials, making them highly desirable for use in the widest range of power isolation applications in which clean, efficient use of power is required. They are the preferred choice in medical and dental electronics, information technology systems, industrial machinery, lab equipment, household appliances, and in both consumer and commercial lighting systems.

Offering operational voltages of 115V, 230V and 100-115/215-230V, the series reportedly provide superior regulation with a maximum of 2.5 percent voltage drop, and maximum temperature rise of 60°C. A full-width, solid-copper electrostatic shield between primary and secondary is arranged to minimize interwinding capacitance. Transformers are available in seven VA ratings from 250VA to 2500VA, with dimensional profiles ranging from 5.4 x 4.0 x 4.75-in. to 7.7 x 7.0 x 6.63-in.
