Maximum Voltage: 0-60 Hz: 277V to GND; 480V Line to Line 0-400Hz: 125V to GND; 208V Line to Line
Description
The LRE series is designed for 277 volt line-to-ground, 480 volt line-to-line, 0-60 Hz applications. These filters may also be used for lower voltage ratings, such as 120/208 volts, with no adverse effect.
Optional Mounting Hardware
The output side of the filter assembly incorporates an RFI tight compartment (security well) that matches the insertion loss performance criteria of the LRE filters. Optional mounting penetration hardware is available that allows for direct installation through a shielded wall.
The penetration hardware includes a threaded conduit hub (of standard pipe thread), conduit nut, flat washer, and RFI/EMI gasket material.
Custom Attenuation Levels and Case Sizes
All power line filters of the LRE series may be offered in a custom case size and/or with a special insertion loss performance to meet a customer's particular specification. It is often worthwhile to investigate these custom filters as this may result in a filter which is smaller and more economically priced. Please contact the Application Engineering Department for more information.
Maximum System Voltage and Frequency Rating for LRE Series Filters
Maximum System Voltage*: 277V to GND/480 V Line-to-line 0-60 Hz For other voltage and frequency ratings, contact the Application Engineering Department.
*NOTE: UL listing only applies to AC voltage rating.
LRE Series - 100 dB at 150 kHz to 18 GHz
Commercial power line filters of the LRE series are designed for moderate filtering requirements. These filters are typically used on mid-performance modular shielded rooms, screen rooms, or foil-lined rooms. Insertion loss is 100 dB at 150 kHz to 18 GHz when measured in accordance with MIL-STD-220A no load condition and full load conditions.
