Description
Siemens Building Technology SED2-FAN2-20C Variable Frequency Drive Fan Assembly is used to control fan speed within HVAC systems, across air-handling applications, where adjustable airflow, is required for efficient system performance, and energy management. It operates, through a variable frequency drive mechanism that modulates motor speed based on input signal utilising a two-wire configuration, to regulate electrical frequency and optimise fan operation under load conditions. This component installs within fan and control assemblies, enabling controlled speed variation efficient airflow adjustment and stable system operation.
