KNF reserves the right to make technical changes without notice. KNF 05/2026. www.knf.com The performance values for the series models shown on this data sheet were determined under test conditions. The actual performance values may differ and depend in particular on the usage conditions and therefore on the specific application, on the parameters of the components involved in the user's system and on any technical modifications carried out which deviate from the standard configuration or the as delivered condition. If individual designs have been created for specific customers on the basis of...
