Rotary Converter Sizing

Choosing the right size TEMCo Rotary Phase Converter

TEMCo's Superior Rotary Phase Converters produce clean, quality 3-phase power suitable for most any application. For motor type loads see the sizing chart below. For resistive type loads such as ovens, heaters, and spot welders, click here. For sizing information to power non-motor applications such as transformer type welders, power supplies, battery chargers, CNC machines, computers, lasers, or any 3-phase need, call us at (510) 490-2187. We will help you choose the right model to power your application.

Motor Load Application Phase Converter Sizing Guide

  1. What is the HP of the largest 3-phase motor you will need to start?

  2. Is it Easy, Medium or Hard to start? (Click here for starting load help)

  3. Find the appropriate column and motor hp. (Easy, Medium or Hard)

  4. Consider your Total Motor Group Load. (Total HP of motors that will be run, but not started at the same time)

  5. Chose the TEMCo Rotary Converter size that accommodates the power you will need by following the horizontal line to the right. You can always use a TEMCo Rotary Phase Converter that supplies more power than you need now, but one that does not supply enough KW power output will not work.

  6. Be sure you have a large enough single phase supply breaker. The single phase breaker should be two times the amps of your 3-phase motor/load up to the maximum recommended breaker size. (If you plan to run your TEMCo Phase Converter on a single phase generator, be sure to size your generator at three times the KW of the size of phase converter to accommodate the phase converter's inrush current. For instance, if you will be using a XR5 Phase Converter, then you would need a 15KW single phase generator to run it on. If you are running the phase converter on utility supplied power, this does not apply: size breaker as directed above.)

  7. Next select the TEMCo Rotary Converter model that meets your maximum power requirements click here: Phase Converter Models.

  8. Note: all amperage (amps) figures shown below are for units configured for 208-240 volts. Where applicable, for operation at 440-460 volts, devide amperage figures by two for corrected capacity. POWER WAVE XR units are only operable on 208-240 volts.

Remember- using a larger phase converter than you currently need is safe, but one that is too small will not work. Purchasing a size larger will help you plan for the future, in case you need additional power as new equipment is added.
