CPN1 VFD Control Panel

Pre-Engineered NEMA 1 Control Panel

The CPN1 Control Panel is pre-engineered NEMA 1 rated panel for constant pressure applications.

The CPN1 VFD Panel is an economical option for constant pressure control applications of 1.5 or 3.0 HP using a single variable frequency drive (VFD). This pre-engineered simplex control panel features a factory-programmed VFD for your specific pressure control application for easy installation.

The NEMA 1 rated enclosure is suitable for indoor operation and features ventilation for VFD cooling. The CPN1 panel includes one 0-100 PSI pressure transmitter.

CPN1 Duplex Controller

OPTIONAL Duplex Controller
The CPN1 Duplex Controller alternates the lead control of two CPN1 panels or two CP3R panels, based on the accumulated run time of each variable frequency drive (controller must be mounted indoors).  This pre-programmed controller is designed to work “out-of-the-box” to control the lag pump operation in the duplex system to maintain the operating pressure under high demand. The controller features pump run status for both lead and lag pumps and lead pump indication. The lead shift hours are adjustable from 1-24 hours.
