Description
The RONK 5 HP 2SUB ADD-A-PHASE Power Converter Type SUB Type SUB is the ADD-A-PHASE static three phase converter specifically designed for use with deep well submersible pump motors and submersible waste water pump motors. Because these motors are much more specialized than standard T frame motors, they generally require more amps for a given horsepower than the standard motor does. Therefore, Type SUB is built to handle the extra load requirements of this type motor
Operation:
The Ronk ADD-A-PHASE is the finest static phase converter available. The design allows adjustment to provide balanced three phase power at any motor load point up to the converter’s rating. The high operating efficiency and low standby losses make the ADD-A-PHASE ideal in most automated applications. Balanced three phase power is dependent on both the converter and the motor.
If no current is drawn by the load (motor off), voltages will not be balanced. When the motor is energized, the third phase current is supplied by capacitors at an appropriate phase angle. When the motor reaches full speed, a portion of the capacitance is automatically switched out of the circuit, and running current is provided by the transformer and oil capacitors. Changing capacitance will change the magnitude of manufactured phase current. Changing transformer tap will change the phase angle. The ADD-A-PHASE is the only static converter which provides these two degrees of freedom to balance currents.
