Isolation Transformers Deliver 97.5% Efficiency

Chassis mountable, the SHE series power isolation transformers specify a minimum efficiency of 97.5%. The series consists of seven components incorporating a UL 1446 Recognized Class H, 180 degree electrical insulation system and they comply with UL 506/UL 5085, CSA C22, VDE 0805/VDE 0550, and IEC/EN 61558-1. The transformers offer continuous power handling from 250 VA to 2.5 kVA and provide 4 kVrms of isolation between their primary and secondary. Winding configurations make them suitable for use in 115V or 230V applications. Offering operational voltages of 115V, 230V, and 100V to 115V and 215V to 230V, the series provides regulation with a maximum 2.5% voltage drop and a maximum temperature rise of 60?C. Average per piece prices for SHE transformers range from $139.02 to $495.98 each/25. SIGNAL TRANSFORMER INC., Inwood, NY. (516) 239-5777.
