Condenser fan speed controller
Product bulletin
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 20% to 100%
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.

- Page 6 %DI = 55 means that a 5A motor consumes a 2,75 A more current so 7,75 A at inrush and up to medium speed. This means that the P216 is limited to 7,75 A, so it is not possible to connect 2 motors in parallel.
