The CP3R VFD control panel is equipped with one Variable Frequency Drive (VFD) in a ventilated NEMA 3R rated enclosure suitable for outdoor operation and includes a 0-100 PSI pressure transmitter. Each is factory-tested and pre-programmed for your application, which makes installation and startup simple and quick. Built-in features, such as PID control and run time, make this control solution ideal for constant pressure applications. SJE-Rhombus offers a five-year limited warranty on the variable frequency drive and a one-year limited warranty on the panel (excluding the drive). UL/cUL Listed.

Control and alarm system

The Ultra Nator control and alarm system is designed to control two 120V 1HP or 15 Amp single phase pumps. It features two receptacles to accept two 120V pump plugs for easy pump connection, no wiring! In normal operation, the pumps will alternate based on the pump switch level. If an alarm condition occurs (top float activates), the alarm indicator and horn turn on. The pump in use will turn off and the other pump will turn on. Pumping will continue until the pump switch deactivates (bottom float). This alternating action equalizes pump wear. The Ultra Nator system is NEMA1 rated for indoor use. It features a factory-installed power cord, pump activation switch and alarm activation switch for easy installation. In addition to an audible and red visual alarm indicator, the system includes a green power on indicator and green pump run indicators (pump 1, 2). The normal/silence alarm switch is mounted externally for easy operation.
