New Filter Technology Protects Motors in Extreme Environments
SineFormer inverter output filter technology recently introduced by EPCOS is used for frequency converters and drives. In contrast to convention filter topology, the SineFormer simultaneously converts the phase-to-phase voltages into sinusoidal waveforms and thus minimizes the common mode current that can damage motor bearings. By suppressing common mode voltage peaks to … [Read more...]
Inductors: New Magnetic Modules Suppress Noise in LAN Applications
New magnetic modules from EPCOS have been crafted especially for LAN applications. The new devices achieve both electrical isolation and suppression of common-mode and differential-mode interference. These modules are available in single, dual, and quad-port versions and are qualified to IPC/JEDEC J-STD-020C and IEEE 802.3. The electrical isolation can withstand a breakdown … [Read more...]
Line of Small Shielded Chambers Targets Pre-Compliance Test Needs
A new line of small fully anechoic chambers from Netherlands-based Comtest meets a growing need for pre-compliance testing of small products. The chamber design is based on Comtest’s Pan-Shield shielding panels that provide high shielding effectiveness over a wide frequency range. Additional RF absorbers within the chamber prevent reflections from the metal walls that could … [Read more...]
