Runs 220V, 3PH equipment on 220V, 1PH power for light to moderate loads. Made in USA. Important: How To Order... â¢ Do Not install a larger size PHASE-A-MATICTM or Heavy Duty series thinking it will give you more HP. The PHASE-A-MATICTM HP range is determined by the minimum and maximum starting current applied to it at any one time. The largest motor on your machine, or the idler motor, if used, must fall within the minimum and maximum HP range marked on the PHASE-A-MATICTM. Do not add HP of the power feed, coolant pump, etc. These rely on the generator effect of the main motor. The only time you would add the HP of two or more motors together would be if they always started at exactly the same time. â¢ For multiple motor applications, the largest motor must always start first and it must be at least 50% larger than any other motor starting on the same converter. â¢ Two-speed motors are dual HP. Select the PHASE-A-MATICTM with minimum and maximum HP which fall within or very close to the minimum and maximum HP of the motor. For example: A 1-1/2 HP 3,450 RPM motor is 3/4 HP at 1,725 RPM. â¢ Some European soft-start motors draw less starting current than normal and therefore require a smaller than normal converter. Most Taiwanese motors draw greater amperage to start than normal. Therefore, for Taiwanese motors we recommend you use model #PC-600HD for 3 HP motors, model #PC-900HD for 5 HP motors and model #PC-1200 for 7-1/2 HP motor etc. Tech Tip- When To Use Heavy Duty Series PHASE-A-MATICTM â¢ Lathes above 3 HP not fitted with a clutch. â¢ Air compressors (the motor pulley) must be reduced by 1/3, or a 50% larger motor must be fitted. â¢ Long heavy starting cycles, frequent starting or instant reversing, unattended motors, if jogging is required, or if there is a chance of the motor being stalled during use.
