Description
The Johnson Controls VS-FS4-FAN Main Fan For Variable Speed Drives improves HVAC systems by controlling fan speed to optimize efficiency. It runs on a 24V DC input voltage and outputs adjustable 0-10V DC voltage with a maximum current of 100 mA. It is designed for variable speed drives and is easily integrated into HVAC systems to provide accurate airflow control to meet changing needs for heating and cooling. It increases the life of the equipment and decreases operating expenses by increasing system performance and decreasing energy usage through dynamic fan speed control. Because it promotes energy economy without sacrificing comfort, this fan controller is ideal for use in commercial and industrial environments.
