1497B-A5-M12-0-N Control Power Transformer

1497B-A5-M12-0-N is an open control power transformer (CPT) from the Allen Bradley Bulletin 1497B series, used to reduce the main circuit voltage of 120 × 240 V AC to 120/240 V AC, providing isolated power for control circuits such as contactors, relays, and PLC power supplies. 1497B-A12-M15-0-N is an Allen Bradley Bulletin 1497B series open control power transformer (CPT) with a rated capacity of 1500 VA, used to reduce the three-phase main circuit voltage of 380/400/416 V AC to 115/230 V AC, providing isolated power for control circuits such as contactors, relays, and PLC power supplies.

    product detail

    Suitable for occasions that require 120V or 240V control power supply, it can supply power to relays, contactors, PLC power modules, etc When selecting, the VA values of all loads working simultaneously in the control circuit should be added together, leaving a margin of 20-30%; 200 VA can usually carry 10-15 small relay coils or equivalent loads Due to the absence of a fuse holder (suffix -0-N) at the factory, quick break fuses or circuit breakers need to be installed separately on the primary and secondary sides in accordance with NEC and local regulations to achieve short-circuit protection Typical applications in 120/240 V power distribution systems such as machine tools, pump stations, and conveyor lines require safe isolation and compact control cabinets
