Filters for Power Lines (Low Leakage Current)

40 and 100 A, 100 dB from 150 kHz

B84261

Filter für Netzleitungen (ableitstromarme Schaltung)

Two- and four-line filters

40 and 100 A

Single-stage

Stopband attenuation up to 40 GHz

Features

ꢀ Low volume and low voltage drop

ꢀ Practically no leakage current flow on the grounding conductor in normal operation because of

the capacitor configuration (capacitive circuit to ground only through neutral)

ꢀ Insertion loss to CISPR 17

Design

The electrical components are incorporated in an RF-tight case of high-grade 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 space

around the fixing holes is left as bare metal (unpainted) to ensure good RF contact with metal

surfaces (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 (diameter min.

10 mm²) in accordance with EN 50178 is necessary. For this purpose the filter case have

connecting bolts at each end.

Resistors are incorporated in the filter to discharge capacitors after turn-off.

Installation

Filters are supplied complete with all parts required for RF-tight installation (fixing screws, flanges,

RF gaskets, cable glands) and installation instructions.

No welding is needed on the shielding wall, so any subsequent installation is quite simple. And the

uniform template of the attachment points allows straightforward replacement of a two-line filter by

a four-line filter for example.

Accessories and special versions

RF-tight flexible connector fittings in widths of 25 and 40 mm 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

request.

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.
