Abstract (en)
[origin: EP0653693A2] A device for controlling the voltage drop across an appliance, particularly an electromagnetic appliance, is described. The appliance and a controlling element are connected in series between earth and supply voltage. First means provide an actual current which corresponds to the voltage present across the appliance. Second means define a nominal current. Control means define a quantity to be applied to the controlling element in dependence on a comparison of the actual current with the nominal current. <IMAGE>
