New Johnson Controls P66BAB-1C Elec Fan Speed Control
Johnson Controls P66BAB-1C PRESS ACT MTR SPEED CTLR
The P66 is a pressure actuated electronic motor speed controller. By directly sensing pressure, this device electronically varies the speed of a fan motor. This control can be used with single phase permanent split capacitor and shaded pole motors that are approved by the motor and equipment manufacturer for speed control applications. To prevent overheating, use a ball bearing motor with a service factor of at least 1.25. Controlling head pressure in the condensing section of a refrigeration system is a common application. This control is designed to replace On/Off fan cycling controls, multiple speed motors, condenser floodback systems, temperature fan speed controls, and modulating louver systems
