In Line EMC Compliance Filter

Single Phase AC Power Line
EMI Filters for EMI Compliance

Data


The new AFEUSKFG-D filter,
 is designed to limit EMI leaving a product
 through common-mode and differential-mode.

Fix a product that fails EMC,
 the simple addition of this filter could make your product EMC Compliant!

 

OnFILTER CleanSweep® EMI filters provide substantial reduction of electrical
noise on power lines emanating from equipment in both test lab and in real-life situations. Innovative design accomplishes maximum noise suppression of signals polluting your power lines, freeing sensitive equipment from harmful interference.
Clean power is essential for uninterrupted and problem-free operation of electrical and electronic equipment. As electromagnetic interference
(EMI) spreads through power lines and ground, it causes downtime and errors in today’s equipment and may inflict component damage.
Unique design of OnFILTER CleanSweep® series focuses on the properties of real-life signals on power lines and produces maximum attenuation of the “worst offenders” on power lines.
Filters are very easy to install - just plug it into the wall outlet and plug your equipment into the outlet on the filter.

Data 

 

CleanSweep® 3A AC power line filters provide clean power to equipment up to 360W for 120VAC circuits and up to 750W for 250VAC circuits. It is prudent, however, to leave some headroom for current rating because most equipment has uneven current consumption during its operation and the resulting peak current may exceed maximum rating.

Soldering-Filter

3A AC Power Line EMI Filters

for Soldering Applications

 

Data 

 

 

Soldering process involves physical contact between soldering iron which is connected to power line and your sensitive components. Ever-present noise on the mains and ground may cause significant current between the tip of the iron and components, creating electrical overstress (EOS) that causes component damage, including latent damage.CleanSweep® EMI filters specially designed for soldering applications reduce this EOS current down to negligible levels enabling safe soldering of even the most sensitive components. These filters create electrically quiet "eco-zone" between the AC supply of the soldering iron and ground of the circuit board. Use of CleanSweep® filters for soldering is very simple: plug your soldering iron through small-size filter and connect ground of your workbench or board under assembly to ground terminal of filter.

10A to 30A rack-mounted PDUs


Data

CleanSweep® AC EMI filtered power distribution units provide both advanced surge protection and effective EMI filtering.  ​ Did you know that regular MOV-based surge protectors allow up to 700V spikes to get to your equipment.   

CleanSweep® PDUs uniquely reduce hundreds of volts transients down to just few harmless volts.

CleanSweep® PDUs combine proprietary suppression technology with regular MOVs providing comprehensive transient surge protection for your sensitive equipment.   ​

Power line transients is not the only power problem affecting your equipment. Strong EMI common in any industrial environment causes multitude of malfunction, equipment lock-ups and errors (some of them appear as software glitches). 

CleanSweep® PDUs employ our unique filter technology to provide unparalleled reduction of EMI improving your up-time and reducing defects.

OnFILTER Ground Filters

 

EMI Ground Filters

GLE30-1

Ground_Filter_Bar

For Facility Applications

Data 

 

This ground EMI filter model GLE30-1 connects your equipment to the facility ground via special filtering circuit. It offers suppression of high-frequency noise on ground while maintaining very low impedance to ground. The filter is very easy to connect and it requires no maintenance.
This filter is designed for equipment consuming up to 30A RMS. Though normally current on ground is negligible, safety regulations require that the ground path should be able to withstand the same current as the power circuit itself.

 



EMI Ground Filters

GLE04-01

OnFILTER-Ground-LIne-EMI-Filter-GLE04-01

For In Tool Applications


Data

The new Miniature ground line filter GLE04-01from OnFILTER is designed to reduce noise on ground inside equipment.

The GLE-04-01 filter can be used by equipment manufacturers as well as by the end-users of the equipment since it requires minimal intervention inside the tool and is easy to install. 

OnFILTER can also supply extended-temperature version of this filter for semiconductor IC test as well as customized models to fit a particular tool.

While regular grounding is sufficient for management of ESD risk, it does not address an issue of high-frequency noise (EMI) on ground and resulting electrical overstress (EOS) to sensitive components.

Most manufacturing tools utilize servo and variable frequency motors, switched-mode power supplies, relays, solenoids and other components that generate high-frequency noise which pollutes ground inside the tools.

The OnFILTER Groundfilter GLE04-01 can be connected in line with ESD grounding to provide significant reduction of EMI in addition to maintaining sub-1 Ohm resistance for proper ESD protection.

OnFILTER Performance of CleanSweep EMI Filter with UPS Uninterpretable Power Supplies (UPS) and Electromagnetic Interference (EMI)

While UPS serve essential role in preventing equipment shutdown during power outages, brownouts, etc., they also create substantial levels of EMI that may affect sensitive equipment and components. Our CleanSweep power line EMI filters greatly reduce noise level while allowing UPS to provide uninterruptable power.
