CONDENSER FAN SPEED CONTROLLER
These controllers are designed for speed variation of single phase motors , especially for fan speed control on air cooled condensers . Head pressure control of a refrigeration system , through speed variation of the fan on an air-cooled condenser , results in optimum performance throughout the year .
Using a pressure transducer as the input device to the fan speed controller , gives the most direct and fastest response to pressure variations in the refrigerant system . The controller varies the supply voltage to the motor from 45 % to at least 95 % over the proportional band using the phase cutting principle . If the pressure drops below the adjusted setpoint minus the proportional band , the output to the motor is zero volt or the adjusted min . speed setting . This provides speed variation of permanent split capacitor or shaded pole motors which do not draw more than 12 A ( rms ) full load current .
The controller used for dual pressure input varies the fan speed by directly sensing the pressure changes of two separate refrigerant circuits . The setpoint of each pressure transducer can be separately adjusted . The controller selects the input with the greatest cooling demand to control the fan speed .
The transducers can be used in non-corrosive refrigerant systems . The motor manufacturer should have approved his product for this speed control principle . It is recommended to confirm with the electric motor manufacturer , that the motor can be used with a controller , using the phase cutting principle for speed variation . You can also provide a copy of this P216 product data sheet to the motor manufacturer / supplier for review .
