Control Transformers

This category stocks Allen-Bradley Bulletin 1497 control transformers, covering two primary series: the 1497-N Global Control Transformer line and the 1497-B / 1497-H Control Circuit Transformer line. The 1497-N series is available in VA ratings spanning 80VA through 500VA, with primary voltages including 208V, 240/480V, and 600V at 60Hz, all stepping down to a 120V secondary — a configuration common in North American machine control panels. The 1497-B and 1497-H series extend coverage to 50/60Hz dual-frequency applications and European primary voltages such as 380/400/415V, making them suitable for globally deployed equipment. With over 160 SKUs available, this category addresses a wide range of control circuit isolation requirements encountered by panel builders, controls engineers, and OEM machine builders sourcing step-down transformers for PLC power supplies, relay logic, and operator interface circuits.
