The LiftMaster XF208VAC7 208V Transformer Kit is an OEM replacement and retrofit component designed to adapt select LiftMaster DC-powered operators to facilities with 208-volt electrical service. By providing the proper input-to-control power conversion inside the operator, this transformer kit helps maintain stable logic/control voltage for consistent performance of the motor, control board, and connected safety/accessory devices. It is commonly used in commercial and industrial environments where overhead door operators or gate operators must run reliably on 208V building power without undervoltage issues that can occur when equipment is configured for other line voltages.
Intended for compatible LiftMaster commercial operators, the XF208VAC7 supports applications such as sectional and rolling steel door operators and other AC-motor systems that require a 208V-specific transformer to meet the control voltage requirements specified by the manufacturer. Installation should be performed by qualified personnel with power locked out, following the model-specific service manual and wiring diagram to ensure correct primary connections and proper control circuitry operation. This is not a universal kit; verify the part number against your operator’s model and logic platform before ordering. Using a genuine LiftMaster transformer kit helps preserve system reliability, supports safe operation with integrated accessories, and aligns the equipment with the electrical characteristics of 208-volt commercial power.
