Multiple Circuit Wall Mounted Panel Filters
Superior Performance: For Stringent Requirements.
The Filter Division of ETS-Lindgren also provides custom panels and cases. For example, the individual LRX and Twin LRX series filters may be provided in custom sized cases to adapt to shielding computer racks. Electrical outlets may also be provided as an option on these cases. In other applications, panels may be custom sized to meet unique installation requirements. For custom cases and panels, UL Listing does not apply.
Common Characteristics of General Purpose UL Listed LRX Power Line Filters
The Filter Division of ETS-Lindgren has a wide selection of general requirement and special application UL Listed power line filters rated from 5 to 400 amperes, and we are continually adding UL Listed filters for other requirements. All Power Line Filters are designed and manufactured to UL-1283. The UL record covering these filters is located in Follow-Up Services Inspection Procedure File E116566.
The general purpose series of filters is the LRX model which is designed for 277 volt line-to-ground, 480 volt line-to-line, 0-60 Hz applications. These may also be used for lower voltage ratings, such as 120/208 volts, with no adverse effect. Note that LRX filters are also available as an option for 120/208 VAC, 400 Hz applications; however, these 400 Hz filters are not UL Listed and the case dimensions increase for filters rated over 30A. (UL Listing is not applicable to 400 Hz Power Line filter design.)
Insertion Loss
LRX series filters meet or exceed 100 dB insertion loss from 14 kHz to 18 GHz as measured per MIL-STD-220A full load condition utilizing extended range buffer networks.
Optional Mounting Hardware
LRX series, LRX Twin series, LPRX Wall Panel and LFPRX Floor Panel series filters may be supplied with optional mounting hardware. The penetration hardware includes a threaded conduit hub (of standard pipe thread), conduit nut, flat washer, and EMI/RFI gasket material. The penetration hardware is located on the rear output side of the filter assembly. It penetrates the RFI tight compartment (security well) of the filter which meets the highest performance criteria, a full 100 dB shielding effectiveness at 14 kHz to 18 GHz. This allows for direct installation through a shielded wall or secure area.
