Ronk Type HD Add-A-Phase power converters are ideally suited for use in warning siren systems. Their heavy duty construction is designed to operate under most every condition, including outdoor operation in extreme weather.
Add-A-Phase converters produce balanced three-phase power from single-phase power sources, and configurations to operate more than one motor are available. They can operate a motor at its full load rating, plus normal overload, and can also be adjusted to provide balanced current for a motor running consistently at a lower horsepower load. Add-A-Phase power converters are exceptionally energy efficient, achieving up to 97% efficiency, as opposed to the less than 90% efficiency of most standard power converters.
