Introduction
These Direct Mount pressure actuated condenser fan
speed controllers are designed for speed variation of
single-phase motors.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.
A pressure actuated device, gives the most direct and
fastest response to pressure variations in the
refrigerant system. The controller varies the supply
voltage to the motor from 30 % to at least 95 % over
the proportional band using the phase cutting
principle.
This provides speed variation of permanent split
capacitor or shaded pole motors that do not draw
more than 3 A (rms) full load current.
Cut-off models (fan stops at low pressure) as well as
minimum speed models (fan keeps running at 30%)
are available.
The controllers 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 product
data sheet to the motor manufacturer/supplier for
review.
