Description
An audio frequency is used to control switching processes of energy supply companies. The signals are usually between 150 and 2000 Hz.
These audio frequency signals from the energy suppliers interfere:
- Frequency inverter
- LED Lights
- Lighting control units (Dali USW)
Our audio frequency suppressors keep these audio frequencies out of the downstream customer network. This means that there are no more disruptions or failures.Audio frequency suppressorsAudio frequency suppressors are filter circuits that are tuned to the respective location-dependent audio frequency. The suppressors prevent the audio frequency from being transmitted further in the low-voltage network. In systems where the ripple control signal could cause interference, the use of audio frequency suppressors is advisable. This increases the safety of the system and reduces the risk of failure.
