Selecting the proper phase converter is an important step towards trouble free set-ups. Sizing the appropriate phase converter for hard, medium, soft starting loads, as well as resistive and voltage sensitive loads, or for special applications is an integral part of the evaluation process. Accommodating such specific requirements can ensure optimum performance of your equipment without compromise and achieving your expansion objectives at limited cost.
To determine the size of the converter needed for the intended application careful consideration must be given to the following variables.
Equipment type and brand name (Domestic or Foreign)
- HP name plate rating and/or amperage draw
- Voltage requirements: 208V, 220V, 240V, 550V, 575V, 600V
Other factors such as single phase dedicated utility amperage available in house is essential. Insufficient single phase amperage can limit or restrict the use of larger units. In order to determine the single phase amperage needed to operate the designated 3-phase equipment simply ad your equipments’ total amperage draw and multiply the total by two, your result will determine the single phase amperage required to power one or an entire fleet of 3-Phase equipment.
The Phase-Quest Rotary converter powers induction motors rated at ¾HP to 70HP.
Several variables must be considered when selecting the unit for each application. In some cases over sizing the Phase-Quest Rotary converter is necessary to satisfy the equipments initial motor load during start-up. Scaling up the converters HP to a greater value then that of the equipments actual motor rating will ensure trouble free service high torque starting loads require special attention in that area, e.g. Compressor, punch press etc. In order to simplify the selection process enlisted is a comprehensive list of load to size data.
