The Genie 110846.0002.S is the factory replacement 220V primary control transformer for Genie commercial door operators in the MT (medium-duty trolley), MJ (jackshaft), and MH (hoist) product family. It steps down the 220VAC line input to the 24VAC required by the operator control circuit and low-voltage accessories. This transformer is specific to 220V installations and is not interchangeable with the 120V variant (110846.0001.S); installing the wrong voltage transformer will damage the operator. Applications on 208-240V single-phase or two-wire 220V service lines should use this unit. Correct voltage matching is essential to operator longevity and reliable performance in the MT/MJ/MH commercial operator family.
A: No. The 110846.0001.S is the 120V primary variant and the 110846.0002.S is the 220V primary variant. These are NOT interchangeable. Installing the wrong voltage transformer will result in equipment damage. Always verify the line voltage at your installation before ordering.
A: This transformer steps down 220V AC line voltage to 24VAC for use by the control board and low-voltage logic circuitry in the MT, MJ, and MH operator series.
A: This transformer is designed specifically for the Genie MT (medium-duty trolley), MJ (jackshaft), and MH (hoist) commercial door operator family. It is not confirmed for use in other Genie operator lines such as the J, H, GH, GT, or T series.
A: The output is 24VAC, which powers the control circuitry of the MT, MJ, and MH operators.
A: Confirm your facility supply voltage is 220V AC before installing this part. If your supply is 120V, you need part number 110846.0001.S instead.
