The NEX Series control panel product line (photo) has been expanded to include single-phase duplex models to alternatively control two single-phase pumps. Designed for water-treatment applications, the NEX Series provides alternating control between the two pumps, which serves to equalize pump wear. If an alarm condition occurs, an alarm switch activates the audible/visual alarm system. This system provides override control should either pump fail. Universal pump voltage and control/alarm power allows the control panel to handle three voltages (120, 208 and 240 V). The NEX Series features a compact design, NEMA 4X indoor/outdoor rated enclosure and an integral padlocked latch. Also available are optional control switches and elapsed time meters. — SJE-Rhombus, Detroit Lakes, Minn.
