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 CISPR 17 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 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. 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 16 to 100 A, 100 dB from 150 kHz B84299*B001 B84299*E001 Circuit diagrams 2-line filters 16 and 32 A 63 and 100 A 4-line filters 16 and 32 A 63 and 100 A 3 Filters for power lines 16 to 100 A, 100 dB from 150 kHz Insertion loss αe (typical values at Z = 50 Ω) B84299*B001 B84299*E001 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
