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.

Single-Phase EMI Filters Protect the Power Supply

Introduction

EMI-RFI filters are typically installed on the main power line. However, did you know that single-phase filters may also be used to protect the power supply, PLCs, and sensors?  This white paper explains the benefits of using a single-phase EMI filter to protect these types of equipment. 

Switching devices within a machine generate radio frequency (RF) noise which travels back to the power line of the facility. When an EMI-RFI filter is installed, it blocks this RF noise. However, did you know that EMI-RFI filters can also protect equipment from RF interference and voltage spikes that could be coming in from surrounding equipment?  

The Challenge

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 affect other devices.

Imagine a power supply installed inside a machine located in a large facility surrounded by other large pieces of equipment. How do you think the output supply and sensors are affected?

The Solution

To minimize the risk of interference, install an EMI-RFI filter on the power line. For example, in a three-phase machine application, the filter would protect the entire machine. It would protect the two-phase power line, including the power supply, PLCs and sensors.

The Result

A compact EMI-RFI filter on the power supply input reduces the risk of noise interference in the field and increases machinery life.  Enerdoor is committed to providing the highest level of customer support possible and bringing value to our customers.

Save money and energy with power factor correction

Power Factor Correction is the use of technology to restore power factor as close to unity as possible.  This is usually achieved by the additional use of capacitors to the electrical network. The Enerdoor FINSVG provides a better solution for power factor correction than the commonly used capacitor banks. Unlike capacitor banks, it is immune to harmonics through active load balancing by advanced digital control. The compensation capacity never declines and the system is capable of compensating both inductive and capacitive reactive power. 

The Enerdoor FINSVG offers compensation starting at 30 KVAR with a modular design and can be either wall or rack mounted. It is available starting at 208 Vac and may be installed in either a single unit system or multiple, parallel modules for entire facilities.
