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 4 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.FANSP.CONTROL3AMP2.2/4.2
