Surge Protection

The Belling Lee PPF range make up is similar to the SF range (see Filter Configuration section) with the addition of a varistor. The range of filter configurations are built up by optimising combinations of various styles of inductor with the appropriate capacitors, varistors and other components to give a comprehensive selection of suppression levels and other features to cover the range of electronic equipment currently manufactured to the various specification requirements.
Below shows a diagram of a Premier Protector filter layout including enhanced performance transient voltage protection with earth line choke LE.
