PHASE-A-MATIC™ Static Phase Converter · Simple Installation · Full 12 Month Warranty · Immediate Delivery From Stock · No More Changing Motors or Switch Gear FOR LIGHT TO MODERATE LOADS ONLY RUNS THREE-PHASE MOTORS FROM SINGLE-PHASE POWER AT 2/3 RATED HP* *Refers to wye-wound motors; delta-wound motors will run at 50% rated HP. Delta-wound motors are very rare in the USA, occasionally being found on some imported equipment, and are particularly found on German and Italian machines. PHASE-A-MATIC™ Static Phase Converters have been developed, tested, and thoroughly proven over a 46 year period demonstrating exceptionally high reliability and long life. These converters are the workhorse of many commercial uses and multitudes of home shop machines. LIFE EXPECTANCY: The Static Converter has been in use for approximately 46 years and has already proven itself to be extremely reliable when properly applied. Phase-A-Matic™ was recently able to purchase back the first one that was ever sold, and it is still working fine. It is reasonable to expect the converter to be in good working condition and service for 20 or 30 years or more. We continue to hear back from customers who have them still running their equipment faithfully after 20 years and more. Uses include: Lathes, Mills, Grinders, Drills, Saws, Metalworking and Woodworking Equipment, Printing Equipment, Sewing Machines, Garbage Disposals, Food Processing Equipment, Meat Grinders, Food Mixers and Blenders, Conveyer Belts, and numerous other uses. METHOD #1 Using the PHASE-A-MATIC™ Static Converter only will produce approximately 2/3 normal HP.* This method is inexpensive, the most popular, provides excellent results on most machines tools and numerous other uses. Motor speed is not changed. Most two-speed motors, power feeds, coolant pumps, etc., will operate normally. Motor will instant reverse. There is nothing to change. All switch gear will work normally. *Refers to wye-wound motors; delta-wound motors will run at 50% rated HP. Delta-wound motors are very rare in the USA, occasionally being found on some imported equipment, and are particularly found on German and Italian machines. Caution: Read the following carefully before attempting installation NOTE: It is best to mount the converter upright, not upside-down or side-ways as shown here. 1. DO NOT connect 220V power or a ground or neutral to the center terminal of the Phase-A-Matic™ Static Converter as the resulting dead short will damage it instantly. The single-phase neutral wire is not required for operation of the converter. Properly ground all electrical equipment. Use a grounding clip to attach the ground wire to the conduit box. Resistive or single-phase loads must only be connected to lines A and C. This product is designed for indoor use only. Do not use in wet or damp locations. Do not mount on equipment with excessive vibration. 2. The red indicator light should only come on when the motor is starting and should go out once the motor has reached operating speed. The light should never stay on longer than 3-5 seconds since the converter could be damaged if it stays on longer. When testing the converter for the first few times after installation, keep your hand near the off switch of the machine, ready to turn it off, to prevent damage to the converter due to a wrong or loose connection. 3. For machines with magnetic switch gear, DO NOT connect the Phase-A-Matic™ Static Converter until you identify which two wires operate the magnetics. To easily locate these two wires, connect 220V single-phase power to any 2 of the 3 wires on the machine, and press the start button. When the correct combination is found the magnetics will work. Connect these two wires to the outside terminals of the converter, lines A and C, and the third wire to the center terminal, line B. The magnetics should still work with the center terminal (line B) disconnected. 4. The horsepower of the first motor to start, or Idler Motor if used, must fall within the minimum and maximum HP range on the converter. However, after the first motor, or Idler Motor, has started, motors below the minimum range may then be started and can usually be left running as the main motor is stopped and started. 5. Always start a machine out of gear or in lowest spindle speed at initial hook-up to reduce load. The Phase-A-Matic™ Static Phase Converter has a built-in weak link which is designed to fail rapidly if hooked to a higher horsepower motor. On a lower horsepower motor, the light could stay on after the motor is running, which would cause rapid failure of the converter, thus providing protection against possible motor damage. 6. Fuses should not be used between the Phase-A-Matic™ Static Phase Converter and the motor. A blown fuse still leaves two lines to conduct which can damage the converter. Magnetic starters are preferred. If fuses are used, they should be placed on the single-phase lines L1 and L2. 7. Using the Phase-A-Matic™ Static Phase Converter as in "Method Number 1" will produce approximately 2/3 of the rated horsepower.* *Refers to wye-wound motors; delta-wound motors will run at 50% rated HP. Delta-wound motors are very rare in the USA, occasionally being found on some imported equipment, and are particularly found on German and Italian machines. 8. Heavily loaded applications, such as compressors, blowers, water pumps, hydraulic pumps, etc., the motor pulley diameter must be reduced by 1/3, or a 50% larger motor must be fitted. Otherwise, "Method Number 2", the Idler Motor System, could be used. Or, use the Phase-A-Matic™ Rotary Converter. 9. Power may be left on the converter without the load applied. Current draw is approximately 8mA (.008 amp). The converter operates best when mounted vertically with the conduit box on top. Installation should be performed by a qualified electrician. Refer to local codes for proper wire sizing. Wires should be sized as appropriate for the motor's rated amperage. This unit is not recommended for use with phase-loss monitors. METHOD #2 FOR FULL OR CLOSE TO FULL HP ~~ Configure as a rotary converter using Phase-A-Matic™ static unit ~~ Full or close to full HP can usually be obtained by running a three-phase motor and PHASE-A-MATIC™ Static Converter combination as shown on the Installation Instructions shown below. When running unloaded, the windings of the motor function as a rotary transformer or generator while consuming very little extra power. The Idler Motor shown in method 2 below needs to be at least 50% larger than the largest motor that you want to run to accommodate the higher starting current. A good quality 3600 RPM, three phase wye-wound, 220V motor is the best choice. 1800 RPM motors can be used on applications not heavily loaded. Used three-phase motors are inexpensive and readily available. When using this method, it is possible to run multiple machines as long as the idler motor is large enough to handle the largest load it would ever have at any one time. For instant reversing of the load motor, as in rigid tapping, the idler motor must be a minimum of twice the HP rating of the load motor, and perhaps more. The Static Converter is sized to the HP of the idler motor, not the load motor(s). Extra Precautions For Idler Motor Systems Heavy starting loads may cause the output voltage on line B to drop sufficiently to cause the Static Converter to return to the starting mode. At this point, the converter's start circuit has the combined HP of the idler motor and the load motor. This will be indicated by the light on the converter coming on when the load motor is started. If the combined HP is greater than the converter's maximum HP range, DAMAGE TO THE CONVERTER MAY OCCUR. To prevent damage to the converter, place a heavy duty, single pole switch on line B, between the Phase-A-Matic™ Static Converter and the three-pole switch. The switch must be in the "on" position before the idler motor is started and turned to the "off" position after the light on the converter has gone out. This will prevent the converter from being damaged by an overload. Never turn the switch back to "on" while the idler motor is running. Doing so could cause damage to the converter. See following diagram. Method Number 2 Isolation Switch Installation Troubleshooting A. If the motor fails to start, and any of the following symptoms occur: clicking noises from the converter, light flashes on and off and motor just hums or buzzes, motor starts intermittently and light goes off before motor reaches operating speed; this could indicate that either the motor is wired for 440 volts, or the Phase-A-Matic™ Static Phase Converter being used is too high in horsepower for the motor, and a smaller size converter should be tried. Also, check for proper connection of magnetics as per paragraph #3 above, or improper overload heaters in magnetics. B. No voltage when measured across lines B and C without motor running: Normal. C. Converter occasionally hums when motor is turned off: Normal. D. Motor runs backwards: Reverse the three-phase lines A and C. Static Converter Application Notes 1. WHAT TYPE OF CONVERTER SHOULD BE USED? The most important question is whether or not the motor is heavily loaded. You must keep in mind the fact that the motor will produce approximately 2/3 of its rated horsepower when running on the static converter. If the motor is loaded beyond that point, you must use our Rotary Converter, or use method number 2 as explained in the Installation Instructions. Otherwise, you must unload the motor by reducing the motor pulley diameter by 1/3 or increase the motor horsepower size by 50% to accommodate the loss of power. NOTE: For the following outlined applications you MUST use a Rotary Converter. Battery Charger Plasma Cutter Some CNC Equipment EDM Machine Radar Transmitter (Radio & Television) Heating Elements Rectifier Variable Frequency Drive Laser Rheostat Welder 2. REGULAR OR HEAVY-DUTY SERIES? Next you must determine whether to use a Regular Duty or Heavy-Duty converter. Keep in mind you can always use a Heavy-Duty converter in place of a Regular Duty one. A Heavy-Duty converter will not provide greater horsepower. However, there are some static converter applications for which you should always use the Heavy-Duty series. These are: 1. Frequent starting (more than once a minute). 2. Instant reversing. 3. Unattended equipment, such as air compressors. 4. Long, heavy starting cycles, such as lathes without a clutch, flywheel driven equipment, etc. 5. If jogging is required. 6. If there is a chance of the motor being stalled during use (woodworking equipment, etc.). 3. WHAT HORSEPOWER RANGE CONVERTER SHOULD BE USED? Next, you must find the proper horsepower range for the application. The largest motor on the machine, or idler motor if used, must fall within the minimum and maximum ranges of the converter. Two speed motors are usually dual horsepower. For example, a 3 horsepower 3600 RPM motor is 1-1/2 horsepower at 1800 RPM. You should select a converter with a minimum and maximum range, which will accommodate both horsepower ratings. However, with Taiwanese and Chinese motors, the larger horsepower should be at the lower range of the converter whether it is a two-speed motor or not. For example, for a 5 horsepower Taiwanese motor you should use a 4-8 horsepower range converter, even if it is a two-speed motor with 2-1/2 horsepower on the low speed. This is because Taiwanese and Chinese motors draw more amperage during start than do domestic motors and therefore require a slightly larger converter than would normally be used. A larger size converter will not provide greater horsepower. A Few Additional Items to Remember: 1. The first motor to start on the converter must fall within the minimum and maximum horsepower range on the converter. However, after the first motor has started, motors below the minimum range may be started and can usually be left running as the main motor is stopped and started. 2. Do not add the horsepower of the power feed, coolant pump, or other accessory motors when sizing a converter. The only time you would add the horsepower of two or more motors together would be if they always start at exactly the same time. 3. A larger size converter or a Heavy-Duty series converter will not produce greater horsepower than a Regular Duty converter. 4. Heavily loaded equipment usually consists of equipment with pumps, blowers, fans, compressors, etc. Payment Winning bidder has 24 hours to make contact with seller.
