Interference suppression filter board De Dietrich 7776775

The interference suppression filter board is designed to reduce electromagnetic interference (EMI) and radio frequency interference (RFI) in heating systems. It filters out noise from the mains supply and from internal switching circuits, ensuring clean power for the boiler or burner electronics. This board is crucial for meeting regulatory standards and preventing malfunctions caused by electrical disturbances. When servicing gas burner parts or boiler control panels, a reliable interference suppression filter board improves system stability and protects sensitive components from voltage spikes.
