The Allen-Bradley 1497-N18 Control Circuit Transformer is a mountable, 0.5 kVA control-power transformer designed for 208 VAC input at 60 Hz, part of Rockwell Automation’s 1497 family of control circuit transformers. It is intended to supply control circuitry in industrial panels, powering devices such as relays and contactors that rely on a 208 V source for control power. This N18 variant is documented as discontinued by the manufacturer and appears in distributor catalogs under 1497-N18, reflecting its use in legacy 1497 installations where a panel-mount transformer was required.
