Stancor P-8721 Industrial Control Transformer

Stancor P-8721 is a compact industrial control transformer with a 230 VAC primary and a 24 VAC center-tapped secondary (24 VCT), rated at 0.20 A (4.8 VA) and suitable for control circuits and relay coils in panel installations. It features five terminals—two primary leads and three secondary leads for the center tap—terminated with lead wires, and it weighs about 0.35 lb with overall dimensions near 2.38 in wide by 1.38 in high. The unit is specified for 50/60 Hz operation and carries an insulation test RMS rating of 1500 V, providing margin for rugged industrial environments. Manufactured in the USA as New Old Stock, the P-8721 is a small, isolated power source derived from 230 V mains, commonly used to feed low-voltage control logic, interlocks, and relays in automation equipment where a compact, dual-coil supply is needed without added complexity.
