Acme Electric TB81201 TB Series Transformer

Acme Electric TB81201 TB Series Open Core and Coil Industrial Control Transformer delivers 75 VA of secondary power for control circuits in machinery and electrical panels. The transformer features a multi‑tap primary that supports 220/240/230/460/240/480 VAC input and yields a 110/115/120 VAC secondary, making it adaptable to a variety of regional power standards and panel designs. Operating at 50/60 Hz and configured for single‑phase service, the TB81201 is built with an open‑core and coil construction that simplifies mounting and wiring in control enclosures. This TB series transformer is designed to tolerate momentary inrush when energizing electromagnets and relays, while maintaining stable secondary voltage for reliable operation of timers, relays, contactors and other control devices. Its rugged construction suits industrial environments and panel builders who need a compact, flexible source of 110–120 VAC control power from a higher‑voltage primary, without sacrificing voltage regulation or response time. With its broad primary voltage compatibility and standard secondary, TB81201 fits typical industrial control schemes and replacement scenarios where a 75 VA, 1‑phase transformer is required.
