Abstract (en)
[origin: EP1403885A2] Control unit for a magnetic coil has a voltage source to which the coil is connected, a controlled switch for connecting source and coil, a switch on unit (12, 14) that produces a start signal for switching on the switch and a timer circuit (15) that is connected to the switch on unit to create a time delay between receipt of a start signal and its transmission to the switch. The time delay is dependent of the supply voltage amplitude. Independent claims are also included for the following:- (a) a control unit for a magnetic coil in which the controlled switch is switched when the supply voltage is a minimum and switched off when a measured current value exceeds a maximum, said maximum being dependent on the supply voltage amplitude; (b) and a method for current to a magnetic coil.
