Rotary Phase Converter

Triple Rated

PhaseMAXX (T) Series (Triple Rated) Rotary Phase Converters are supplied with built in magnetic starter, overload protection, and Hand/Off/Auto or Stop/Start controls. These converters can operate single or multiple motors, as well as resistive loads. The KVA capability for resistive loads is 1.3 times the (Largest HP) rating.

Triple Rated rotary phase converters are ideally suited for grain handling, woodworking equipment, hoists, printing machines, irrigation pivots, air conditioners, and machine tools. Motors connected to Triple Rated rotary phase converters will develop full rated HP.

PhaseMAXX (T) Series rotary generators are cast iron products for ruggedness and quiet operation.

When comparing converter prices between different manufacturers, especially compare the HP and frame size of the rotary generator.

Triple Rated Soft-Start

The TZ soft-start series converter reduces the converter's start up amps, as compared to the T series converter. The rotary generators used to create the 3rd electrical phase are sized to be about twice as large as the largest horsepower motor they are powering to provide adequate starting torque for the load. The inrush amps of a locked (stopped) electrical motor is 5-8x its nameplate amps which means that it takes a lot of amps to start up a converter.

Our soft-start series converter reduces the required starting current by about 65%. For example, if a regular triple rated converter required 100 amps, then the soft-start converter would require only about 35 amps.

These inrush amps also affect the utility grid. Everything that connects to the electrical grid affects everything else that is connected to the electrical grid. Minimising power spikes helps create a more stable electrical grid.
