The P266 Series Single-Phase Condenser Fan Speed  Controls are cost-effective, weather-resistant, durable  motor speed controls. The P266 Series Controls are  designed for approved single-phase, Permanent  Split-Capacitor (PSC) motors commonly used in a wide  variety of refrigeration and air conditioning condenser  fan applications. The P266 Series Controls are designed to replace the  Johnson Controls® P66 Series and P215 Series Fan  Speed Controls, providing additional features and  flexibility, greater energy efficiency, and longer motor  life in a compact, rugged, weather-resistant package. P266 Series Controls are available for 208 through  575 VAC 50/60 Hz range applications. P266 Series  Controls have current ratings from 4 to 12 A,  depending on the voltage and model. Some P266 Series Controls provide optional control of  up to three auxiliary (fixed-speed) fans or fan stages. In  addition, some models provide two additional  high-voltage triacs that allow you to split the source  power to the main and auxiliary windings, and connect  a low-speed capacitor to increase efficiency at  low-speed operation.
