White Papers
Enerdoor's White Papers offer detailed datasheets about each of our products.
CE Certification
Enerdoor assists customers through a portion or the entirety of the CE Certification process. We work on-site with the customer to find real time solutions, and offer recommendations and suggestions to minimize potential radio-frequency interference…
EMI-RFI Filters and Pre-Compliance
The manufacturer’s decision to take advantage of the Enerdoor mobile laboratory for pre-compliance testing before moving to the final Compliance test saved both time and money. The potential compliance failure of the machine could compromise the…
OEM Equipment Using VFDs and Servo Drives
This white paper discusses Enerdoor’s approach when customers need to select an EMI-RFI filter in conjunction with single or multiple variable frequency drives (VFDs) and servo drives. Following the VFD and servo-drive specs is not always sufficient…
EMI-RFI Filters and Material Handling Equipment
This white paper discusses a recent Enerdoor success story using an EMI-RFI filter in conjunction with material handling equipment that used VFDs and servo drives to control various motors within the system. Material handling equipment manufacturers…
Motor Protection from Overvoltage Spikes
This white paper discusses Enerdoor’s approach with customers in need of protecting motors against overvoltage spikes, widely known as dV/dt. Voltage wave reflection is a function of the voltage rise time (dV/dt) and the length of the motor cables.…
Motor Protection - The Enerdoor Snubber
This white paper discusses Enerdoor’s newest product the FIN47SNB snubber and how it benefits markets facing voltage wave reflection issues due to the use of variable frequency drives (VFDs). It can be challenging for OEMs, system integrators and…
Power Factor Correction
This white paper discusses Enerdoor’s newly developed product, the FINSVG Static Var Generator and how it benefits markets in terms of saving both money and energy using power factor correction. Unlike capacitor banks, the FINSVG is immune to…
Invisible RF Noise and System Failures
It can be challenging for OEMs, system integrators and distributors to find “invisible noise.” Unwanted EMI and RFI noise can degrade the performance of communication systems and cause false triggering and faulty readings in sensor circuits. Such…
EMI-RFI Parallel Filters
This white paper discusses Enerdoor’s EMI-RFI Parallel Filter and how it fits into our application centered approach when introducing unique products to solve customer specific or market driven needs. For the past 25+ years, this hybrid EMI-RFI…
Single-Phase EMI Filters Protect the Power Supply
A power supply requires clean power in order to avoid noise or interference that could affect sensor life or machinery performance. Larger facilities have several different types of equipment which create RF interference and voltage spikes that…
Ground Noise Reduction
The Ground Noise Reduction filter is a new Enerdoor product designed to improve the quality of the PE ground inside machines. Today’s industrial equipment has a combination of switching devices such as power supplies, servo drives and variable…
EMI-RFI Filters and Glove Box Systems
This white paper discusses a recent Enerdoor success story using an EMI- RFI filter in conjunction with glove box systems. Glove box systems often use thermocouples in order to constantly monitor the temperature variation within the system. Today,…
EMI-RFI Filters and Packaging Equipment
Packaging equipment manufacturers are often challenged to achieve CE Certification, due to the fact that the drives emit high frequency noise that often causes malfunctions with sensors, encoders, HMI screens and e-stops within the system, as well…
