Description
The Johnson Controls P266CHA-100 Fanspeed Control is, therefore, an item developed to accurately control the fan speed in HVAC systems. It uses high voltage of between 380/460V which makes it suitable for use in industries. This control unit is intended for single phase Permanent Split Capacitor (PSC) motors used in air conditioning units and industrial ventilation. Pulse width modulation is used in the P266CHA-100 to control the amount of power supplied to the fan motor and therefore its speed. It affords centralized, precise control of the air flow depending on defrosting or air-ventilating requirements. Another advantage of this control is the enhanced energy utilization in the process.
