Industrial TB-81215-F3 Industrial Control Transformer

The ACME TB-81215-F3 Industrial Control Transformer delivers 500 VA of isolated control power in a compact, open-core, open-coil, dry-type, single-phase package with integrated 3-pole fuse blocks for safety and easy installation. It accepts primary voltages configured as 240/480 V, 230/460 V, or 220/440 V and provides a 120/115/110 V secondary at 50/60 Hz, making it suitable for powering control circuits and electromagnetic devices such as relays, contactors, and solenoids in industrial panels. The open-core design with copper windings and a heavy-gauge steel mounting plate helps minimize voltage drop during energization and supports reliable operation under typical control loads, with a focus on maintaining robust secondary voltage regulation. The TB-81215-F3 rating and construction align with Acme’s TB series open-core transformers, designed to sustain momentary inrush without sacrificing secondary voltage stability, and it carries a 10-year limited warranty. Its compact footprint measures 5.5 in x 5.3 in x 4.5 in, enabling straightforward panel mounting in space-constrained applications.
