Three-phase electric power is a. A three-wire three-phase circuit is usually more. A rotary phase converter is a three-phase motor with special. Wiring diagrams for TEMCo phase converter lines. Learn to hook up your single phase to three phase converter. Units on sale now! Jump to Installation - For single panel units, three-phase wiring to the load should be sized as it normally would be on standard three-phase. For two panel units, size the three-phase wire at 135% of the three-phase load's amperage. All fuses or breakers for the converter and motor loads should be time delay types to. STATIC PHASE CONVERTER. 3 Wire the PHASE -A MATIC static phase converter to the idler. Converter and the 3-pole switch - refer to Method No.

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. 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. 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.

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. Sriram Ias Economy Notes. The magnetics should still work with the center terminal (line B) disconnected. 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. Shorts Vector Free Download Air. 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. 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.

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. 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, could be used. Or, use the Phase-A-Matic™. Power may be left on the converter without the load applied.
