The RONK 1.5 HP 2HD ADD-A-PHASE Power Converter Type HD is the ADD-A-PHASE static three phase (3?) converter designed for equipment that must operate under most every condition. Type HD is built with components that allow for greater reliability on these types of applications. This unit has been successfully used on warning systems and on pipeline installations throughout North America. Due to its heavy duty components, Type HD can also be used on applications that require many starts per hour – 60 or more.
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.
