CE Certification With Industry Leader

As one of the largest EMI-RFI filter manufacturers in the world, Enerdoor also offers a flat rate, on-site CE Certification and consulting service.

Benefits of being CE compliant

When equipment is CE compliant, facilities run more efficiently, which results in both logistical and economical benefits. CE compliant equipment reduces emissions that can negatively affect other machinery and also protects machinery from non-compliant equipment causing external radio frequency (RF) interference. These benefits save time and money by avoiding production downtime due to EMI-RFI issues. 

Do you need CE testing? If you ship products or equipment overseas, the answer is yes.

Enerdoor is here to help your company achieve worldwide regulation and Standard approvals. All complete OEM equipment must meet CE Standards, and generally follow these three major Directives:

  • EMC Directive 2014/30/EU
  • Machinery Directive 2006/42/EC
  • Low Voltage Directive 2014/35/EU 

Has your customer ever complained about RF or electrical issues?

Enerdoor solves RF and electrical issues due to switching frequency devices such as: VFDs, servo drives, power supplies and SCRs.  

Do you know the majority of sensor failures are due to electrical spikes and radio frequency interference?

Radio frequency interference inside your cabinet can disturb sensors and other sensitive, low-voltage devices. Safety sensors, for example, may trip unexpectedly from RF interference, prompting the machine to immediately shut down causing production downtime and costly repairs.  

How often do you need to repeat CE Certification?

As long as the critical components listed in the EMC Directive do not change, there is no need to ever re-test the machine. Prior to testing, Enerdoor makes recommendations that often allow one test to certify an entire family of equipment instead of just one machine.

What is the difference between Enerdoor and other CE and EMC test service providers?

Enerdoor has specialized in the measurement and analysis of CE Certification and EMC testing for over 25 years, providing service to customers around the world. Our flat rate, on-site testing is unique in the industry, as is our pledge to not leave your facility until a solution is found. Enerdoor engineers assist customers through a portion or the entirety of the CE Certification process.

Enerdoor offers several fully equipped EMC mobile laboratories, complete with engineers with decades of on-site experience. At Enerdoor we pride ourselves in working on-site with customers to find real time solutions and offer recommendations to minimize potential radio-frequency interference that may cause malfunctions inside the machine or to other devices.

EMI-RFI Filters for OEMs Using VFDs and Servo Drives

As one of the largest EMI-RFI filter manufacturers in the world, Enerdoor offers solutions to customers needing an EMI-RFI filter in conjunction with single or multiple variable frequency drives (VFDs) and servo drives.  

It can be challenging for OEMs, system integrators and distributors to find the proper EMI-RFI filter to use inside a cabinet that has multiple VFDs or servo drives.                    

Drive manufacturers often recommend installing a single EMI-RFI filter for each individual drive. This results in increased cost, more space being used inside the cabinet, and a higher leakage current. Typically, drive manufacturers do not stock EMI-RFI filters, due to the fact they view filters as an accessory and feel they are not responsible for supplying all necessary components in the final system. This tends to make it difficult to purchase these devices.

The Solution
Enerdoor proposes one filter per machine instead of one filter per drive. Using a single filter per machine instead of one per drive offers the following advantages:  

Technical:  Low leakage current; protects the entire machine instead of only the drive. 

Economical: Using only one filter costs less, requires less mechanical space, reduces potential quality issues due to faulty wiring, and accelerates installation time.

The Result
Enerdoor’s unique combination of being an EMI-RFI filter manufacturer and decades of experience with the Enerdoor EMC mobile laboratory has allowed us to comprise a list of filters compatible with the major VFD and servo drive manufacturers of the world. 

All filters listed here have been tested in systems utilizing single or multiple VFDs. If a drive manufacturer is not listed, please contact Enerdoor for the appropriate solution.

EMI-RFI Filters Reduce High Frequency Electromagnetic Noise

EMI-RFI Filters are an electronic device used to suppress conducted interference from a signal or power line. Most electronics require an EMI filter either as a separate device or as a built-in circuit board to reduce high frequency electromagnetic noise between the drive and the mains power supply.

Since 1992, Enerdoor has been a global leader in EMI-RFI filters offering single phase, three phase, and three phase + neutral filters.
