An isolation circuit for preventing the current surges drawn by a direct current cooling fan from appearing in the output of the power supply. The fan has one terminal connected to one terminal of the power supply, and a regulator circuit connects the other terminal of the fan to the other terminal of the power supply. The regulator circuit includes a capacitor connected across the fan to provide a low impedance circulating path for the current surges, and it also includes a network which provides a constant current to the parallel combination of the fan and capacitor.
