The 274AX is a multi-tap power transformer designed to provide multiple voltage outputs from a single primary input. It features primary voltage inputs at 117V and 125V with 50/60 Hz operation, and offers multiple secondary outputs including 720VCT at 138mA, 5V at 3A, and 6.3VCT at 3.5A. The transformer includes various color-coded winding configurations (WHT-BLK, WHT-RED, RED-BLK, RED-RED, YEL-BLK, and GRN-GRNYEL) with power ratings ranging from 18VA to 35mA, and DC resistance values measured at 20°C ranging from 0.553O to 163.6O. This transformer is commonly used in control circuits, instrumentation, and power distribution applications where multiple voltage levels are required from a single source.
