Swallow Electric Co. SUL-HH-1500E-0071 Transformer

Swallow Electric Co. SUL-HH-1500E-0071 Transformer is a 1.5 kVA, single‑phase power transformer designed for 220 V mains input. It belongs to Swallow’s SUL overseas‑standard family intended for Canada and the USA, featuring a double‑winding construction that accommodates a wide primary voltage range (approximately 190–240 V) and provides secondary voltages in the commonly used 100/110/120 V range, depending on configuration. With a 1,500 VA rating, it supports moderate loads such as laboratory equipment, small appliances, or AV gear sourced from higher-voltage mains, while maintaining isolation between primary and secondary windings for safety. The SUL‑HH variant identifies a specific 1.5 kVA model within Swallow’s North American lineup, offering a compact solution for voltage conversion where 220 V input must be stepped down to standard household voltages.
