DoorKing 4001-088 Transformer 575/460/230/208-115V
- Step-down transformer with four primary voltage taps: 575 VAC, 460 VAC, 230 VAC, and 208 VAC; secondary output: 115 VAC
- Enables DoorKing gate operators that nominally require 115 VAC to be powered from industrial three-phase or high-voltage commercial supply voltages — the correct primary tap is selected at installation to match the available supply voltage
- For 9000, 6500, 6300, 9150, and 1600 series operators, a step-down transformer allows input AC voltage to be altered from 115 VAC to 208, 230, 460, or 575 VAC input
