| Filters for Power Lines (Low Leakage Current) 40 to 100 A, 100 dB from 150 kHz Series/Type: B84261 Date: January 2004 (c) EPCOS AG 2004. Reproduction, publication and dissemination of this data sheet, enclosures hereto and the information contained therein without EPCOS' prior express consent is prohibited. Purchase orders are subject to the General Conditions for the Supply of Products and Services of the Electrical and Electronics Industry recommended by the ZVEI (German Electrical and Electronic Manufacturers' Association), unless otherwise agreed. Filters for power lines (low leakage current) 40 to 100 A, 100 dB from 150 kHz B84261 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. 2 Filters for power lines (low leakage current) 40 to 100 A, 100 dB from 150 kHz B84261 Circuit diagrams 2-line filters 4-line filters 3 Filters for power lines (low leakage current) 40 to 100 A, 100 dB from 150 kHz Insertion loss e (typical values at Z = 50 ) B84261 Asymmetrical measurement circuit to MIL-STD-220A General technical data Rated voltage 2-line filters Rated voltage 4-line filters Rated frequency Rated current Maximum admissible overcurrent VR VR fR IR Iover 250 440 250 50/60 See characteristics 75 IR for 50 ms 10 IR for 1 s 2 IR for 1 min 1.4 IR for 15 min 1200 VDC, 2 s 1200 VDC, 2 s <1 See characteristics V V V Hz Referred to +40 C ambient temperature Line/line Line/case Line/line Line/case Test voltage Voltage drop/phase Maximum DC resistance Vtest V Rmax Line/line Line/case % Of VR at 50 Hz and IR Per line 4 Filters for power lines (low leakage current) 40 to 100 A, 100 dB from 150 kHz B84261 General technical data (continued) Power dissipation Capacitive leakage current Max. permissible harmonic distortion (THD) Permissible ambient temperature Climatic category (EN 60068-1) Mechanical version TA PD Ileak See characteristics See characteristics 8 25/+40 25/085/56 C D At rated current IR Difference potential N to PE at 50 Hz % To EN 50160 C 25 C/+85 C/56 days damp heat test Cable glands at both ends or flexible connector fitting Direct connection to shielding wall Characteristics and ordering codes IR A Mechanical Rmax version m <5 <5 < 10 < 10 <4 <4 PD W < 16 < 16 < 50 < 50 < 120 < 120 Dimensional Page Approx.
