Abstract
The disclosed power supply is compatible with two voltage ranges, the midpoint or mean of the higher voltage range being approximately double the midpoint or mean of the lower voltage range. Two equivalent loads and two current sources are re-configured using a relay in response to a detected input voltage exceeding a pre-determined threshold voltage. The disclosed circuit re-configures the load being driven to match the input voltage, rather than re-configuring the voltage to match the load.
