Voltage adaptive solenoid control apparatus
摘要:
An apparatus (10) is provided for controllably operating at least one solenoid coil (12) in a battery operated system. The mean voltage applied to the coil (12) is controlled in response to at least the battery voltage, facilitating the use of various battery voltages with a single voltage coil (12). The apparatus (10) is readily adapted for controlling multiple coils (12) and is digital in design.
