INDUSTRIAL CONTROL TRANSFORMERS
Industrial control transformers are used to reduce supply voltages to 240V or lower for the operation of electromagnetic devices such
as contactors, solenoids, relays, and timers. They are especially designed to accommodate the momentary current inrush caused
when electromagnetic components are energized without sacrificing secondary voltage stability beyond practical limits.
Acme Industrial Control Transformers are dry-type, step-down transformers with the secondary control circuit isolated from the primary
line circuit to assure maximum safety.
Voltage regulation of Acme Industrial Control Transformers exceeds standards recommended by the National Electrical Manufacturers
Association. Secondary circuit voltage drop between no-load and momentary overload remains exceptionally low. This excellent
secondary circuit voltage regulation assures reliable operation of electromagnetic components and may permit the use of a smaller
and less expensive industrial control transformer.
TB SERIES INDUSTRIAL CONTROL TRANSFORMER
Acme’s TB Series Industrial Control Transformers are especially designed to accommodate the momentary current inrush caused when
electromagnetic components are energized... without sacrificing secondary voltage stability beyond practical limits.The transformer’s
windings and internal terminations are sealed within an epoxy encapsulant encased in a durable thermoplastic end cap, protecting
them from potentially damaging moisture, dirt and other ambient contaminants. Acme’s TB Series transformers are dry-type, step-down
transformers with the secondary control circuit isolated from the primary line circuit to assure maximum safety.
