P315PR Condenser fan speed controllers for EC motors

The direct mount pressure actuated condenser fan speed controllers are designed for speed variation of electronically commutated (EC) 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. The controllers can be used in non-corrosive refrigerant systems. A pressure actuated device provides the most direct and fastest response to pressure variations in the refrigerant system. The controller varies the supply voltage to the motor from 5% to at least 95% over the proportional band.
