Industrial TA-1-81215 Control Transformer 500 VA 240 480 V Pri 120 V Sec Volts

Acme Electric TA-1-81215 is a 500 VA industrial control transformer that converts a 240/480 VAC primary supply to a 110/115/120 VAC secondary for control circuits. It is rated for 50/60 Hz operation and designed for single-phase use in equipment and control panels to power relays, timers, PLC I/O, and other control devices from standard higher-voltage mains. The TA-1-81215 model specifies a 500 VA rating with a primary voltage range of 240/480 V and a secondary of 110/115/120 V, aligning with common North American control-system architectures where 120 VAC control voltages are derived from 240 or 480 VAC lines. Typical applications include powering control circuits in industrial machinery, automation lines, HVAC controls, and panel-board power distribution where an isolated 120 VAC supply is required from a higher-voltage source.
