EF Series

Compact RFI Filter with IEC Connector

UL Recognized
CSA Certified
VDE Approved

15EF1F - UL, CSA: 15 Amps/250VAC
VDE: 10 Amps/250 VAC

Catalog Data Sheet

EF Series

This rugged international series of RFI filters incorporates the special IEC power line connector. They are UL recognized, CSA certified, and VDE approved.

Electrically the EF international series are general purpose filters effectively providing RFI control of line-toground noise. The design is compact and meets the very low leakage current requirements of VDE portable equipment as well as (120 Volt) UL544 non-patient medical equipment. Models with F suffix have .250” terminals on load side; EF4 and EF8 have wire leads.

Model 10EF1FC additionally incorporates a separate ground-circuit inductor to isolate the equipment chassis from power line ground at RF frequencies.
