Abstract
A method for providing electrical current to a contactor circuit, by providing a power supply circuit having a power supply resistor, the power supply circuit supplies electrical current to the contactor circuit in response to the electrical specifications of the contactor; selecting a value for the power supply resistor in response to the contactor's electrical specifications and requirements of the contactor circuit; and, inserting the selected power supply resistor into the power supply circuit.
Claims8
A method for providing electrical current to a contactor circuit, the steps comprising:
- providing a contactor having a coil;
- providing a printed wiring board on which the contactor circuit is located;
- providing a power supply circuit located on the printed wiring board, the power supply circuit receiving electrical current from the contactor coil and supplying power to the contactor circuit;
