The Alex-Tronix LS Latching Solenoid is a 12 VDC two-wire polarized latching solenoid. It requires a short DC pulse to turn it on, and a reverse polarity DC pulse to de-energize it. No energy is required to keep the valve open. The LS can be operated directly by the Enercon controllers. Alex-Tronix recommends using the model LS (Latching Solenoid) with all of its battery powered controllers.
*Black lead is the common and the red lead is the positive. Connecting the leads in reverse will cause valve to stay on when it is supposed to be off, and off when it’s supposed to be on.*
