General Information
.
CAUTION: Always start converter before applying load.

1.

Magnetic controls or  single-phase  loads (including electronics, microprocessors, etc.) must  always be energized  by  lines T-1 and T-2.  

2. Never connect  a ground  or neutral to line T-3 (manufactured phase), which can easily be identified as the line with the highest voltage to ground with the converter running.
3.

It is essential that careful consideration be given to your wiring length and size to prevent slow starting due to a voltage drop. Consult Electrical Code for proper wire sizing.

4.

Due to the high starting current (in-rush current) common to electric motors, a drop of starting torque may occur when using a converter that is too small. Because of this, it is NOT advised to size an application KW for KW. The vast majority of applications require sizing the converter 100% larger or more than the largest KW rated motor of your equipment. See Application Notes for sizing considerations, or call 1-800-962-6976.

5.

The tables  below show the approximate idle current at 415V. Higher line voltage will cause idle current to increase. Excessive amperage could also be caused by incorrect installation.

6. Voltage sensitive equipment (CNC/PLC, 3-phase powered electronics, etc.) may require a Phase-A-Matic™ Voltage Stabilizer designed to reduce phase voltage imbalance. See Voltage Stabilizer, or call 661-947-8485. 
7. Properly ground all electrical equipment.
8. Converter should reach full speed within 2 to 3 seconds.
9.

Lubricate every 12 months for normal operation, or every 6 months for continuous (24 hour)  operation.  Use   high  temp  bearing  grease: "Exxon POLYREX®EM" polyurea grease or equivalent available from Phase-A-Matic, Inc.

10.

Converters  are intended   for  use  in  clean,  dry locations  with  access to an  adequate supply  of cooling  air.  In  addition,  there   should  be  protection  from or avoidance of flammable  or combustible  materials  in the  area  of  converters as they can eject flame and/or metal in the event of an insulation failure.

11. "KW" series Rotary Converter is 400-480V single-phase in and 400-480V three-phase out, 50Hz and 60Hz use.

1.
Largest Motor KW:  Almost all machines require sizing the converter 100% larger or more than the largest KW motor rating of your machine. See paragraph #4 above. Also refer to Sizing For Load Types.

2. Minimum Single Phase Supply: Single-phase supply shown is for absolute maximum output of the Rotary Converter. Most of the time the converter is oversized to provide the high starting current for the motor. It is not always necessary to use single-phase breakers sized this large. Contact Phase-A-Matic, Inc. for smaller single-phase breaker qualifications. 

IMPORTANT: 
This chart is simplified and cannot reflect the many types of applications possible. Contact Phase-A-Matic, Inc. at 1-800-962-6976 to verify your phase converter requirements. Also refer to Application Notes for sizing considerations.

Larger Horsepower phase converter systems may be obtained by connecting multiple Rotary Converters in parallel. This is necessary for output greater than 55 KW. Contact Phase-A-Matic, Inc. for help..
