2- and 4-line filters 16 to 32 A
Multi-stage
Stopband attenuation:
B84299*2*B/E001 150 kHz to 40 GHz
B84299*2*B/E003 14 kHz to 40 GHz
Features
General-purpose use through design with separate lines without intercoupling
Use of single chokes. Thus the insertion loss values are not reduced under all operating current
conditions and not when operated with artificial mains networks (AMN) or other equipment with
high leakage currents
Insertion loss to EN 55017
Design
The electrical components are incorporated in an RF-tight case of stainless steel. The cables enter
through glands. The RF-tight termination of the openings is produced by specially shaped lids.
The conductors and equipment grounding conductor are connected by threaded bolts. The surface
around the fixing holes is left as bare metal (unpainted) to ensure good RF contact with metal sur-
faces (chassis, ground).
Protective measures (grounding)
The high capacitances between the lines and ground require special protective measures. If there
are no product-specific requirements, protection with a secondary ground wire (cross section min.
10 mm) in accordance with EN 50178 is necessary. For this purpose the filter case have connect-
ing bolts at each end.
Resistors are incorporated in the filter to discharge capacitors after turn-off.
Scope of supply
Filters are supplied complete with all parts required for RF-tight installation (fixing screws, flanges,
RF gaskets, cable glands) and installation instructions.
Installation
No welding is needed on the shielding wall, so any subsequent installation is quite simple.
Accessories and special versions
RF-tight flexible connector fittings are available for installation spaced away from the shielding wall.
Filters with an EMP protection add-on for surge currents up to 100 kA per line are available on re-
quest. To match requirements, filters can be supplied with different kinds of EMC or shielding cable
glands.
Tests
All filters are 100% tested and the results are archived under a filter's serial number. If required, a
test report can be generated for the serial number.
