Condenser Fan Motor Speed Control

Approved for single phase psc motors commonly used in many refrigeration and air conditioning condenser fan applications.

Condenser fan motor speed control.

How to connect the fan wire easy to understand fan coil connector 5 wire condenser fan motor wiring diagram simplest. 3 speed ac fan running capacitor. 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 ecm variable speed fan motors are used in condensers that have a modulating compressor.

They are also used in condensers that have two compressors or a two stage compressor. Single or three phase fan speed controllers. Instead of slamming the condenser fan off and on the fan speed control will slow the fan down. The control monitors the head pressure by sensing the sub cooled liquid line temperature.

This electronic head pressure control modulates condenser fan motor speed thereby varying the air volume through the condenser. There are two temperature inputs and three outputs pwm 0 10 vdc and 10 0 vdc to control the ecm or vfd variable speed fan motor. Variable speed ecm condenser fan motors are used in condensers for the high efficient models so that the fan speed for the condenser can be modulated according to the load of the system. The p266 series single phase condenser fan speed control is a cost effective weather resistant durable motor speed control.

Wide adjustable pressure throttling range. The johnson controls condenser fan speed control is a cost effective weather resistant durable motor speed control. Cut phase controllers in master or slave version designed for adjustable voltage 3 ph motors from 8a to 60a. As the condenser pressure or liquid line temperature starts to fall the fan motor will slow down.
