EMI/ RFI Filter

What is an EMI Filter?

An EMI filter, or electromagnetic interference filter, is an electronic passive device used to suppress conducted interference present on a signal or power line. EMI filters are used to suppress interference generated by the device, or by other equipment, to protect a device from electromagnetic interference signals present in the environment. Most EMI filters consist of components that suppress differential and common mode interference.

To protect and optimize equipment, Enerdoor EMI/ RFI filters provide solutions in three product categories: single-phase, three-phase, and three-phase plus neutral filters.

Types of EMI Filters

Available with terminal block, cable, screw and bus bar connections and with finger safe protection for screw and bus bar options.  DIN rail mounting provides fast and easy installation into the enclosure.  Enerdoor offers solutions in traditional TN and TNS networks and in specific applications such as IT power line configurations. Customized voltage, current, connection, and attenuation solutions are available to satisfy various application needs.

Enerdoor three-phase plus neutral filter series offers a current range from 1 to 2000A with nominal voltages up to 600 Vac. This series provides high attenuation in a compact case with low leakage current and is suitable for several industries.  Available with terminal block, cable, screw and bus bar connections and with finger safe protection for screw and bus bar options.  DIN rail mounting provides fast and easy installation into the enclosure.  Customized voltage, current, connection, and attenuation solutions are available to satisfy various application needs.

电机保护

Enerdoor developed the Motor Protection series to protect motors from harmful overvoltage and dV/dt spikes generated on the output. This is particularly useful for applications with variable frequency drives and servo-motors. 

This series includes common mode and differential mode inductances, sine wave filters and snubbers designed to work with various frequency switches, output frequencies and applications.  

The sine wave filter series reduces the pulse wave modulation (PWM) effect, converts the PWM to a sine wave and reduces dV/dt. The FIN915SF model is used with fundamental frequencies up to 2 kHz. The high frequency inductance FIN960F is a unique solution used for synchronous spindle motor applications.

谐波滤波器

Power quality is a significant concern for manufacturing and power generation facilities. This is due to harmonic disturbance and reactive power, which is produced by unbalanced loads, variable frequency drives and motors. These issues have serious consequences, including prematurely aging of equipment, unreliable controls, system synchronization loss, and increased energy, maintenance and replacement costs.

Enerdoor is an industry leader in radio frequency interference solutions. The Enerdoor harmonic filter series solves harmonic disturbance and power quality issues by compensating current harmonic and power factor correction generated by industrial loads.

Power Factor Correction

MRI 滤波器 – 军用滤波器

The Enerdoor medical filter series is designed to achieve a high level of shielding on protected environments. All models are characterized by high levels of attenuation above 100 dB. For each application there are models suitable for filtering supply lines 50 and 60 Hz from single phase to three phase, with currents of up to hundreds of amps and filters for signal lines (remote controls, lines connecting sound, video, telephony, digital signals).

Models are characterized by a leakage current to ground (below 30 mA), which allows use in any environment without the need of special installation procedures. All models are built and tested conforming to all military regulations: MIL.F-15733, MIL-STD-220A and Civil UL1283.

Product range includes models suitable for various applications where required attenuations are equal to or greater than 100 dB, with different possibilities in terms of frequency band, depending on the application.

Filters for military applications: 10 KHz - 10 GHz
Filters for medical applications in a 5 MHz - 5 GHz
Filters for applications scientific and industrial laboratories, for example, measuring 100 KHz - 10 GHz 

稳压器

The Enerdoor voltage stabilizer series regulates voltage through a series of transformers. A static control circuit drives the variable autotransformer that supplies the required voltage to a series transformer, either in phase or out of phase, to bring the mains to the rated value. 

Three-phase stabilizers are available in two versions:
The models FINSTT and FINSTC perform voltage regulation by an average of three phases and are suitable for lines with balanced voltage and for an unbalance between phases up to 50%. These models are equipped with one stabilizing circuit to ensure a common regulation of the three-phase and may be connected to input mains without neutral.

The models FINSTTY and FINSTCY are equipped with one stabilizing circuit for each phase and are suitable for unbalanced mains with a maximum unbalance between phases up to 100%. For correct operation, the input line must be three-phase + neutral. Voltage regulators do not transform the voltage and therefore have the same output voltage as the input. When input and output voltages are different, an additional isolating transformer or auto-transformer is required.

避雷器

The Enerdoor surge arrester series has been specifically designed to offer surge protection for electrical equipment. Surge arresters are installed at the front end of a system for the purpose of diverting harmful overvoltage transients caused by external (lightning) and/or internal (switching) events to ground safely. Also known as Surge Protection Device (SPD), or Transient Voltage Surge Suppressor (TVSS), Enerdoor surge arrestors protect against electrical transients resulting from lightning strikes that find their way onto electrical conductors.

All models include remote contact, visual indicator, and comply with the UL 1449, IEC 61643-11, and VDE 0675 International Standards. DIN rail or screw mounting options are available with select models offering plug and play replaceable cards for quick and easy installation and replacement.
