The PowerMaster Model T Drawbar Operator is engineered for reliable operation of standard lift sectional doors in commercial and industrial facilities. This operator is built with a continuous-duty, high starting torque motor protected by current-sensing or thermal overload devices. A full-voltage, across-the-line magnetic reversing contactor ensures smooth directional control, with electrical components housed in a NEMA 1 enclosure. The integrated transformer reduces control voltage to 24 VAC, and dedicated terminal strips simplify wiring for both power supply and external control devices. The operator is designed with a heavy-duty V-belt primary reduction and chain-and-sprocket secondary reduction for dependable performance under demanding conditions.
