Ultra Low Leakage Power Filter Range
A high performance range of 2 Phase or SP&N, 3 Phase and TP&N Power Line filters with ultra low line to earth leakage current supporting system/equipment compliance with overarching requirements of NATO TEMPEST SDIP-27 and SDIP-29 standards. They provide high attenuation from 100kHz to 10GHz suitable for use in TEMPEST and other secure information handling applications.
Insertion Loss Performance
Typical asymmetric insertion loss shown when measured in reference 50Ω system in accordance with CISPR 17 at all loading conditions.
Typical Applications
- Marine Applications
- Low leakage land based platforms and equipment
Features
