Applications

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.

3A AC Power Line EMI Filters

for Soldering Applications

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.

OnFILTER DIN Rail Mounted EMI Filters
	OnFILTER's new line of DIN-rail mounted EMI filters brings performance and feature of stand-alone and panel-mounted existing filters to convenient DIN rail configuration.

AV Series DIN Rail AC EMI Filters	DIN-rail mount CleanSweep power line noise filters are specifically designed to provide clean power in control panels. They block EMI on real life power lines (both common mode and differential mode) from reaching your sensitive equipment.

DIN Rail Narrow Band PLC Filter	PLC, or power line communication, is a powerful tool to control equipment without adding wires or alternative communication channels. PLC is not without its challenges, however. PLC signals often reach equipment for which they were not intended to. Creating multiple PLC networks on the same AC power line is asking for troubles. Strong EMI interferes with PLC signals usually located in the same band as typical EMI. CleanSweep AM series DIN rail PLC filters answer all the above challenges. They serve as a separation junction for two separate narrow-band PLC networks on the same AC main.

DIN Rail Ground EMI Filter GLV30-1	This patented ground EMI filter is most suited for blocking EMI in electrical panels. "Dirty" ground entering panel can cause unstable performance or outright malfunction.

Dual DC EMI Filter DVNG5009 50V 2x9A	This dual DC filter provides substantial reduction of electromagnetic interference on DC power lines in two independent galvanically separated circuits up to 9A each or up to 18A when connected in parallel. Filter provides noise suppression in both directions protecting your DC lines from noise generating by a particular piece of equipment, or protecting your sensitive equipment from noise coming from DC power supply or other loads. DC filter DVNG5009 offers unrivalled flexibility in configurations - see Applications below. Filter uses plug-in terminal blocks for connections and DIN rail mount for easy installation. Its small size makes it easy to fit in many panels. DVNG5009 has many uses - noisy DC supplies, LED lighting, and others.

Servo Motor / VFD Filter DIN Rail SV20101	Servo / VFD EMI filters help to substantially reduce EMI in the equipment and to protect motor's bearing from EDM-caused fluting. These patented filters are complete multiple-mode filters, providing comprehensive noise reduction, not just reactors. DIN rail mount SV20101 is most suited for motors consuming up to 10A. Our panel-mounter servo/VFD filters offer 20A version. If you are looking to include an AC input filter for the drive, please see our panel-mounted combo model which combines in one small package both motor and AC filters.

Stepper Motor Filters	PWM-driven motors, such as stepper motors are a major source of electromagnetic interference (EMI) in equipment. They also cause a number of 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.

Dual DIN Rail Mounted Data Filters	Long data lines from and to 4...20mA loop sensors and actuators "collect" plenty of noise which causes data misreading, errors and other malfunction. OnFILTER' data electromagnetic interference filters for such analog lines block EMI on long cables while providing pass through for the data. We offer two models - for slow-changing signals (under 500 Hz) and for fast-changing signals (under 10 kHz). The former provides the best noise suppression while the latter accommodates wider variety of sensors and actuators with faster data rate, such as HART (highway addressable remote transducer) protocol. Most applications would use "slow" model.

OnFILTER Ground Filters
EMI Ground Filters GLE30-1 For Facility Applications	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 For In Tool Applications	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 DC Power Line Filters

DC Power Line EMI Filters

This DC filter provides substantial noise reduction on DC power lines of up to 50V 9A. Filter provides noise suppression in both directions protection your DC lines from noise generating by a particular piece of equipment, or protecting your sensitive equipment from noise on power line.

OnFILTER Power Line EMI Adapters
Hand-Held EMI Adapter for Power Lines Power Line EM Adapters MSN15 & MSN17	MSN15 and MSN17 are the logical continuation of our well-established EMI Adapters MSN01 and MSN12. Here is a brief comparison: MSN15 is a NEW MSN12. It has much broader bandwidth (up to 200MHz vs. 30MHz in MSN12) and is designed to appeal to a wider range of customers, specifically those working with power line communication (PLC) and data security (yes, power line is yet another entry into your computers and servers in data centers).

System-Level Grounding - Doing it Right

Is Grounding Done for Safety? For ESD? For EMI?

Yes, yes, and yes. In many factories and facilities grounding is done using only one, seldom - two of these elements, often neglecting other aspects. A facility electrician worries about safety. An ESD specialist thinks of compliance with ESD standards. And whoever worries about EMI (this function often falls now on ESD group) may not know enough about safety requirements to assure proper compliance.

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.
