Abstract:
A solenoid control system for solenoid operated transfer switches used for switching an electrical load from a first electrical power source to a second electrical power source, the system comprising:a transfer switch switchably connected between the first power source and the load and the second power source and the load; a rectifier, the rectifier being connected to at least one of said power sources; at least one solenoid, the solenoid being mechanically coupled to said transfer switch; at least one solenoid control circuit, wherein the solenoid control circuit comprises a CMOS timer integrated circuit for controlling the solenoid, the control circuit connected to said rectifier and said solenoid; and a controller, the controller being connected to said solenoid control circuit whereby the controller sends a signal to the solenoid control circuit thereby causing the solenoid to move the transfer switch from one of said power sources to the other.
