Schneider Electric 1S1FIS 1KVA Dry Transformer

Schneider Electric's Square D 1S1FIS 1 kVA dry-type transformer is an encapsulated, single-phase device that steps a dual-voltage primary of 240 × 480 V down to a 120/240 V secondary. This 1 kVA unit uses a dry, encapsulated construction and carries a 7 A rating with a 115 °C rise (TA A), aligning with common industrial and commercial requirements for power conditioning in control panels and equipment. Available in a NEMA 3R enclosure variant for indoor or outdoor installations, it provides reliable isolation and voltage conversion from higher-voltage sources to 120/240 V circuits such as relays, sensors, PLCs, and other 120/240 V devices. With Square D engineering, the 1S1FIS model is designed to integrate into standard electrical distributions where a compact, single-phase transformer is needed to supply low-voltage control and auxiliary circuits from 240/480 V mains.
