The Control Station operates using voltages generated by the HPN9033A power supply. The power supply operates from a 115 / 230 VAC (switch selectable) power source. The power supply provides power for the fan assembly and radio. The power to the interface electronics is obtained from the radio's accessory connector. The power supply has three connectors:
- One pigtail with a 2-prong "Ford" connector to mate with the radio power connector.
- One pigtail with a 6-position connector to power the fan.
- One IEC ac receptacle for various line cords (U.S. Standard, 3-prong, 115 VAC cord provided).
A slide switch on the power supply allows thermal control or continuous ON fan operation.
