A high-voltage, AC power supply for an electrostatic discharge system comprises a chassis shaped to define an interior cavity, a high-voltage transformer for increasing the voltage received from an external power source, and an output connector module in electrical connection with the transformer for delivering the increased voltage to a high-voltage load, such as one or more anti-static bars. The transformer and the output connector are independently mounted onto the chassis within the interior cavity in a spaced apart relationship and are electrically coupled through one or more flying lead connectors in order to facilitate assembly. During operation, a resistive damping component in the output connector module regulates the output voltage and secondary current delivered to the load in order to render the power supply less susceptible to dielectric breakdown from partial discharge.
