SECTION
TA Series Open Core & Coil
Industrial Control Transformers
Industrial control transformers are used to reduce
supply voltages to 230 V 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.
