P215PR 1-phase condenser fan speed control

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.
