An electronic control arrangement for controlling the power applied to an electrical load, in which the electronic control includes in its memory a predetermined power control parameter look-up table associated with each of a plurality of potentially applicable voltage ranges. Each table contains the appropriate control parameters for controlling the load when the associated one of the input voltage ranges is applied to the load. The control, in response to an input signal identifying the voltage to be applied, selects the control parameters from the look-up table associated with the identified voltage. This signal may be generated by voltage sensing circuitry which monitors the supply voltage, or by a manually adjustable circutt which enables presetting for a particular supply voltage. <IMAGE> |
