Signal Transformer, a subsidiary of Bel Fuse Inc., announces the availability of the SHE (Super High Efficiency) Series of chassis-mount power isolation transformers boasting 97.5% (min.) efficiency. Specifically provided 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 Signal’s extensive portfolio of standard and custom power transformers for worldwide applications. The seven-part series incorporates a UL 1446 Recognized Class H, 180 degree 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 4000 Vrms 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.
Signal’s Super High Efficiency transformers utilize optimal quality core and conductor materials, making them highly desirable for employment 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 features superior regulation with a maximum of 2.5% voltage drop, and maximum temperature rise of 60 degrees C. A full-width, solid-copper electrostatic shield between primary and secondary is arranged to minimize interwinding capacitance. Transformers may be ordered in seven VA ratings from 250VA to 2500VA, with dimensional profiles ranging from 5.4’ (L) x 4.0” (W) x 4.75” (H) to 7.7 (L) x 7.0” (W) x 6.63” (H). Weights range from 11.75 lbs. to 56.54 lbs. Incorporated connections are IP-20 rated touch-safe terminals offering 3/16”, Ľ” quick-connect terminals, and binding clamps with Pan Head Phillips fasteners. Custom orders are readily accommodated.
