Example of Matrix Filters- Manufactured by MTE

Overview:

MTE Matrix Filters solve the problem of harmonic distortion on virtually any kind of six pulse rectifier. These power supplies are commonly found in three phase electronic equipment such as adjustable speed motor drives, uninterruptible power supplies (UPS),welders, battery chargers, servo drives and other equipment.

Harmonics are a problem

Harmonic distortion has become an increasing concern for facility managers, users of automation equipment and specifying engineers alike. Harmonics not only waste energy, but they reduce equipment life, electrical system reliability, system efficiency and equipment productivity.

Guaranteed results

Unlike other harmonic filter technologies, the performance of MTE Matrix Harmonic Filters is guaranteed! On AC variable frequency, variable torque drive applications (fans &pumps), Matrix filters will meet the guaranteed maximum levels of THID (total harmonic current distortion) all the way from no load to full load. Additionally, Matrix filters will not cause power system resonance nor attract harmonics from other non-linear loads.

Convert 6-pulse Drives to Multi-pulse Harmonic Performance

Matrix filters allow users to achieve attenuation of harmonics to levels below that previously attainable only by using 12-pulse or 18-pulse rectification methods. Use standard 6-pulsedrives and our M5 Series Matrix Filters in place of 18-pulse rectifiers and use our M8 Series in lieu of 12-pulse rectifiers.
 

Typical uses include:

Mission critical facilities
AC variable frequency drives
DC adjustable speed drives
Uninterruptible power supplies
Electronic welders
Battery chargers
Fans and Pumps
Water Treatment Facilities
Induction heating equipment
Elevator drives
3-phase power supplies
Any 6-pulse rectifier

 

Matrix Harmonic filters are UL Listed (File E180243) for both USA and Canada.
Meets international power quality standards such as: IEEE-519, G5/4, AS2279, EN61000, UL Listed (UL-508C)

 

Why are Matrix Filters Necessary?

They Increase Reliability

Matrix Filters reduce the burden on electrical equipment by reducing TRUE RMS (trms) current, peak current and harmonic frequency distortion. The series impedance included in the Matrix filter also absorbs transient over voltages just like a line reactor, to prevent over voltage trips and rectifier damage. Increased system reliability means higher productivity.

They Increase Equipment Life

Matrix Filters reduce the trms current that flows through equipment feeding non-linear loads. This reduces the amount of heat generated by upstream equipment (such as transformers, disconnects, fuses, circuit breakers and conductors), thus extending their life expectancy.

They Reduce System Harmonics

Matrix Filters can reduce adjustable speed drive system harmonics to negligible levels.

They Reduce Current Waveform Distortion

Matrix Filters improve the input current waveforms of non-linear loads to nearly sinusoidal. This results in lower peak current and trms current demands while achieving a cleaner power supply.
They Save Energy!

By nearly eliminating the wasted energy associated with harmonics, Matrix Filters reduce the trms KVA demanded from a power source.

Typical Savings:

10HP motor rating - 5% savings

50HP motor rating - 10% savings

125HP motor rating - 20% savings

150HP motor rating - 30% savings

They Meet IEEE-519

Matrix Filters allow you to meet the voltage and current distortion limits of IEEE-519, EN61000,
AS2279 and G5/4.
