ACME Electric TB81200 Industrial Control Transformer

ACME Electric TB81200 Industrial Control Transformer is a 300 VA, single‑phase open‑core transformer designed to convert higher‑voltage power into a stable control‑voltage supply for relays, timers, solenoids, and other control devices in industrial equipment. It accepts primary voltages of 240 V, 480 V, or 600 V and provides a 120/100 V secondary at 50/60 Hz, delivering reliable voltage to control circuits while isolating the secondary from the mains. Built for rugged use, the TB81200 features windings and internal terminations encased in a durable thermoplastic end cap and open‑core, coil construction, which supports quick energization of electromagnetic components and helps manage momentary inrush without excessive secondary voltage drift. The transformer is rated for 80°C insulation and is designed to withstand typical industrial environments where safe, isolated control power is required for devices such as contactors, relays, and other control circuitry.
