These controllers are designed for speed variation of 3-phase motors, especially for fan speed control on air cooled condensers.
Head pressure control of a refrigeration system, through speed variation of the fan, results in optimum performance throughout the year.
Using a pressure transducer as the input 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 96% over the proportional band using the phase cutting principle.CONTROL 400VAC 50/60HZ NO
