Filters for power lines (low leakage current)
B84261
40 to 100 A, 100 dB from 150 kHz
2- and 4-line-filters
40 to 100 A
Single-stage
Stopband attenuation 150 kHz 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 surface 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 (cross section 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.
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. And
the uniform template of the attachment points allows straightforward replacement of 2-line filters
by 4-line filters for example.
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 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.
