<p>An integrated module encased in protective housing is electrically and mechanically connected to a solenoid (20), which remotely actuates an Automatic Transfer Switch (ATS) (10) or lighting contactor. The module includes a full-wave bridge rectifier (42), voltage transient voltage protection circuitry (44), a proximity detector (54) to determine the solenoid's plunger (58) position, and a mounting strap to attach the solenoid to a frame. In addition, the module accepts various resistor values as plug-in devices (74) to reduce a line voltage and incorporates a communication device/modem for connection to the Internet. The module allows a fixed voltage across the solenoid coil, and permits the solenoid to be connected to various operating voltages.</p> |
