Core & Coil – Control Transfomers (Up to 3kVA)
Industrial control transformers (also known as machine tool transformers) fill the size range from 25 to
7500 VA and up to 600 VAC. They are used to step-up or step-down the supply voltage for the operation
of electromagnetic devices such as timers, relays, contactors or solenoid switches. A critical element in
their proper usage is to supply correct voltage during short-term periods of inrush currents, providing
isolation to control components from power surges and lighting circuits. Marcus offers a broad range of
control transformer options to satisfy our customer’s requirements. If the unit will be installed inside a
cabinet or panel, choose our option style with standard screw terminals. All open type models are
available with leads upon request. For standalone installations, we have the closed type and an epoxy
encapsulated model (MEC) for harsh environments. Our Buck-Boost transformer can be connected for a
wide variety of voltage combinations. Whichever model you select, you can be assured of Marcus quality.
All our industrial control transformers are manufactured with bobbin-wound copper coils incorporating
high quality insulating materials, superior grade laminations and extremely rugged solidly fixed terminals.
This ensures that they operate more efficiently and are more reliable than comparable brands.
