P66 Series Electronic Fan Speed Controls

The P66 is a pressure actuated electronic motor speed controller.  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.  by directly sensing pressure, this device electronically varies the speed of a fan motor.  Controlling head pressure in the condensing section of a refrigeration system is a common application.

Features and Benefits

Exclusive Pressure Transducer:  Rapidly responds to changes in air delivery requirements.

Soft Start: 
Provides a smoother startup.  This significantly reduces motor starting noise and abrupt changes in motor speed, which could occur between zero and full output voltage.

208-240/277/480 VAC, 60 Hz Motor Control: 
Universal model can be used on a wide range of voltage applications.

One or Two Pressure Transducers:
Useable with single and multi-circuit condensers.  The control selects the input with the greatest demand. 

Two Effective Throttling Ranges (ETR):  Allows choice of 30 or 60 psi.

NEMA 1 or NEMA 3R (Rainproof) Enclosure:
  Enclosures available for indoor or panel mounting and for outdoor mounting application.

Built-in Voltage Surge Protection, Radio Frequency Interference (RFI) Suppression, and Grounding Terminal Screw:
