Single Phase, Duplex Motor Alternating Pump Control with Override
The SPF Series™ duplex panel is designed to alternately control two 120, 208 or 240 VAC single phase pumps in water and sewage installations. The alternating action equalizes pump wear. In addition to the alternating pump control, this system provides override control should either pump fail. If an alarm condition occurs, an alarm switch activates the audible/visual alarm system. The compact design (10” x 8” x 4”) is ideal for residential applications. Universal pump voltage and control/alarm power allow the SPF Series™ panel to handle three voltages (120/208/240V). The innovative internal design of components and integral mounting tabs make installation quick and simple. Includes integral padlockable latch for added safety.
