DC Filter Inductors
-
Osborne DC filter inductors (aka filter chokes) are commonly used in AC to DC conversion circuits to present an inductive voltage drop to the AC component of rectified current. This inductive voltage drop acts as a filter. Osborne designs filter inductors to components to function effectively (without saturation) in the presence of the DC current. Osborne will work with you to mitigate the impact of ripple frequency in conversion circuits. Every Osborne DC filter choke is designed for high performance with special consideration given to your circuit´s power supply frequency and conversion configuration.

How much EMI noise is on your power lines indeed? How to assess the levels of noise and its properties when it is obviously a bad idea to connect your oscilloscope or a spectrum analyzer directly to your power lines?Our EMI interface adapters provide a barrier for high mains voltages but a straight passage for high-frequency signals so that you can connect your sensitive instrument to power lines for analysis and quantification. We offer plug-in and hand-held adapters which can measure both differential ("normal") and common-mode noise.

MEMS Tunable Filter
-
Optoplex’s MEMS Tunable Optical Filter is based on a patented micro-optic design with MEMS tuning technology. It is an integrated module consisting of a MEMS chip, micro-optics and control electronics and interface. When receiving a stream of optical signals of a plurality of wavelengths from the Input-Port (IN), the 2-port tunable optical filter directs a selected channel to the Output-Port (OUT). Wavelength (frequency) tuning is achieved by changing driving voltage applied to the MEMS chip, via the control electronics and the built-in firmware.

Blocklist Based Filtering
-
Many businesses prefer to use blocklists prepared by external intelligence agencies to save the time of generating this data themselves. Also, to get as much exposure and intelligence of the threat landscape as possible. However, this blocklist information can be sent in various formats, making utilizing them a challenge. Luckily, FastNetMon is a flexible blacklisting feed filtering tool that supports a vast array of formats to receive, consume, and use blocklists from different intelligence feed providers. FastNetMon then enables you to block specific malicious and dangerous hosts using blocklist-based filtering.

High-Power Tunable Filter
CB503
-
The need for tunable filter technology originates from the fact that high power communication systems and IED Jammer transmitters severely limit the use of tactical radio communication systems on the battlefield.This clash within the radio’s spectrum during tactical missions is often de-conflicted using fixed high Q, high power RF bandpass and bandstop filters installed prior to mission. This can limit operational effectiveness due to the potentially large number of fixed filters required within the allocated radio communication channels, which need be transported, stored in the field, and fitted by trained personnel. Many of these fixed filters centred within the octave wide tuning range could be replaced by a single high-Q tunable filter.

LV Iron Core Harmonic Filters
-
Nonlinear loads such as power electronics based equipment and electric furnaces are sources of harmonic currents leading to harmonic distortion, which is one of the most important parameters for defining the power quality. Most of the commercial loads such as personal computers, photocopy machines, power supplies, and compact fluorescent lamps; and industrial loads such as AC and DC motor drives inject harmonic currents into the network that they are connected to.

Servo And VFD Filters
-
Operation of PWM-driven motors – servo motors and variable frequency drives (VFD) – causes several problems in equipment, including damage to the motor’s bearings due to leakage current causing electrical discharge machining (EDM) and damage to motor’s insulation. PWM motors also are a major source of EMI in equipment. These motor drive systems use pulsed power to drive the motors. As we are aware, the sharp edges of the pulses inevitably include high frequency components which can couple or radiate as noise to other parts of your system and cause unreliability, communication/control problems and EMC compliance issues.
