A programmable power supply provides multiple output channels that may be independently driven to vary the frequency and duty cycle of each channel. The power supply includes the capability of receiving a program via a program interface on the power supply. The power supply also includes the capability of reading a program from a device that is plugged into the power supply's output connector. In this manner, a device to be powered (such as an EL panel sign with multiple segments) may contain a program that specifies how the segments are to be driven. This allows the power supply to dynamically reconfigure itself for many different signs by simply plugging a different sign into its output connector. The preferred embodiments also provide an improved connector system for EL panel signs, and includes output compensation to automatically compensate for degradation in an EL panel over time.
