Abstract
A power supply converts an AC input voltage to a DC output voltage and supplies the DC output voltage to power devices. The power supply includes a housing, a transformer provided in the housing for reducing a voltage level of the AC input voltage and a thermal protection device thermally connected between the AC input voltage and the transformer for electrically disconnecting the AC input voltage from the transformer when activated responsive to the transformer exceeding a predetermined temperature. A rectifier is electrically connected to the transformer for rectifying the AC input voltage reduced by the transformer into the DC output voltage which is supplied to the power devices.
