NEX Series® Duplex Control Panels

NEX Series® Single Phase Duplex Control Panels

Single phase, duplex motor contactor control.

The NEX Series® duplex control panel is designed to alternately control two 120, 208, or 240 VAC single phase pumps in water and wastewater applications.  The alternating action equalizes pump wear.  In addition, 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 (25.4 x 20.32 x 10.16 cm) is ideal for residential applications.  Universal pump voltage and control/alarm power allow the NEX Series® panel to handle three voltages (120/208/240V single phase).  The innovative design of internal components and integral mounting tabs make installation quick and simple. 

NEX Series® Dúplex

Panel de Control Dúplex Monofásico

Panel de Control Compacto Monofásico, Dúplex con alternación y anulación de bombas

El panel de control NEX Series® dúplex está diseñado para controlar y alternar dos bombas monofásicas de 120, 208 ó 240 VAC en instalaciones de agua y aguas residuales.  Además de controlar la alternación de las bombas, este sistema proporciona un control de anulación si cualquiera de las bombas falla. Si se produce una condición de alarma, un interruptor de alarma (flotador) activa el sistema de alarma audible/visual.

El diseño compacto (25.40 X 20.32 X 10.16 cm) es ideal para aplicaciones residenciales.
El voltaje universal de bomba (s) y de control/alarma permiten al panel NEX Series® manejar tres voltajes (120/208/240V). El innovador diseño interno de los componentes y pestañas de montaje integradas hacen que la instalación sea rápida y sencilla.
