This series of rotary phase converter is capable of operating an unmanned simplex, duplex, or triplex pumping station. It incorporates a built-in magnetic contactor, time-delay relay, and overload protection that is capable of interfacing with the pump control panel in order to automatically start the converter before the pump equipment is energized. The automatic controls of the Roto-Phase converter work well with a float switch or pressure switch activated pump system.
The Automatic Roto-Phase is a Rotary 3-Phase converter--not a static phase converter! Automatic control incorporates magnetic starter and time-delay relay, enabling Roto-Phase to Automatically energize 5 to 15 seconds before load motor energizes. The Automatic Roto-Phase is particularly suitable for 3-phase sewer lift stations, water pressure systems and similar applications using centrifugal, close-coupled, turbine and submersible pumps--variable speed, constant speed or SCR. 3-phase motors can operate from a single-phase line of 230 V. or 460 V. Eliminates maintenance or balancing of motors. The Automatic Roto-Phase is compact, completely pre-wired and ready to use. Units are available from 1½ to 75 horsepower. Roto-Phase should be selected in capacity equal to largest 3-phase motor used. Weatherproof fiberglass enclosures are available as an option.
