multiwave Active

Suitable products for every requirement

multiwave Active 30A / 50A (3-phase)

Even the smallest version of multiwave Active guarantees compensation of harmonics up to the 50th harmonic, as well as reactive energy. Small dimensions and low weight enable a simple and space-saving installation in every situation: both wall-mounted and cabinet assembly are possible up to protection type IP 54. With a power dissipation of only 1300 W, this model is extremely economical. The reaction time of less than 300 μs in the UltraFast mode makes it possible to optimally compensate even dynamic consumers.

multiwave Active 30A / 60A (4-phase)

multiwave Active 30A/60A also compensates the harmonics occurring in the neutral conductor and is particularly suitable for compensating the third harmonic and all those dividable by three, up to the 50th harmonic. Due to its low noise development, this device is ideal for building technology – e.g. for banks, computing centers and hospitals.

multiwave Active 100A / 120A

Although hardly larger in size and weight than the compact version of multiwave Active, this device is suitable for twice the amperage. This makes this filter an excellent solution for all those who require more power and are looking for a central coupling to their consumers. The 3-phase and 4-phase technology enables it to be used in almost all surroundings.

multiwave Active 200A / 250A / 300A

Intended for amperage up to 300 amps, this version of multiwave Active is suitable for the highest technical requirements as can be found in large production plants – for example in the automotive industry. So that it can work reliably even when the going gets rough, the filter in the cabinet version contains an interior air ventilation and additional internal fluid cooling for the power electronics, with an integrated water-air heat exchanger.

The solution for better network quality


Many companies have problems with their power system quality. Safety and cost-effectiveness are central factors in companies. Here, one requirement for optimal results is the faultless operation of the technical infrastructures in the form of machines, production facilities or office equipment. This is however frequently not the case: usually without an evident reason, and despite UPS back-up and emergency generators. The consequences:

  • Cables and networks cannot be fully loaded
  • High energy losses in the networks
  • Increased wear and tear and limited availability of facilities
  • Failure of devices and facilities

Often, the reason for breakdowns and premature wear and tear are quality problems in the internal power system. Measurements and network analyses have repeatedly proven this.


multiwave Active eliminates harmonics and reduces the costs for reactive power. Nearly all non-linear consumers in the industrial world cause massive voltage distortions of the original pure sine curve. This is where multiwave Active is applied. Harmonics up to the 50th harmonic, as well as cost-intensive reactive power, are eliminated directly and reliably. This ensures a high network quality and reduces costs. The savings achieved through the reduction in reactive power are already reflected in lower operating costs. Savings made as a consequence of lower equipment wear, less troubleshooting or the prevention of production stoppages have a significantly higher impact. For this reason, multiwave Active pays off within a short time.

{slide The advantages}

As an active harmonic filter of the newest generation, BLUEWAVE offers many advantages over conventional technology. multiwave Active is powerful, compact, fully digital, reacts within microseconds and reliably compensates current harmonics and reactive power. With these features, the active harmonic filter presents itself as an all-in-one device for excellent power quality.

Compact models for all requirements
Whether building technology or automation technology: with its extensive range of models, multiwave Active is ideal for the most diverse applications. Versions of the devices range from 30 to 300 ampere and 380 to 480 volts – in 3-phase or 4-phase technology..

Rapid compensation almost in real-time
The faster an active harmonic filter reacts to disturbances in the network, the more exactly it compensates them. Since multiwave Active is fully digital, a reaction time of less than 300 microseconds is possible. This way, multiwave Active ensures excellent power quality and protects power supply units, cables and machines

Resilient towards external influences
In industrial environments, cleanroom conditions cannot always be guaranteed. The high-tech components in multiwave Active are therefore protected against external influences. The 30 ampere and 50 ampere versions are by default equipped with protection type IP20, and thus protected from dust. The 300 ampere version is also splash-proof, according to the protection class IP54.

High performance in a confined space
In comparison with other active power filters, multiwave Active requires little space. In its 50 ampere version, the external dimensions of the device are only 36 x 59 x 29 cm and it weighs less than 50 kg. This makes wall assembly possible without any problems

{slide Areas of deployment}

The number of companies and institutions that could significantly optimize their network quality with multiwave Active is huge. The efficient active harmonic filter is optimally suited for use in building technology, as well as in systems engineering and automation technology. In this context, it makes sense to already include the device in the planning and implementation stages of new facilities. Of course, multiwave Active can also be intelligently integrated into existing facilities and institutions with power quality problems



Click-and-start configuration
multiwave Active offers supreme flexibility, as it can be coupled to the energy supply on the load or network side via a variety of current transformers. Configured with just a few clicks, the existing network current is permanently measured and any harmonics or phase shifts occurring are actively compensated. Within microseconds, multiwave Active calculates the appropriate compensation currents, makes these available and feeds them into the network. Fully digitized controlling along with high computing performance make this possible.

Multilingual menu and control via software
Using a multilingual, menu-guided operating panel and display, the setup, selection and adjustment of individual parameters is very user-friendly for all multiwave Active device types. With the BLUETRACE firmware, installation and maintenance can be performed conveniently via computer. In remote operation via Ethernet and TCP/IP interface, the current status of the network quality can optionally be retrieved online, so that adjustments can be made.



Individual solutions and comprehensive service
So that you can find the optimum solution for excellent network quality, KBR is at your service as a competent multiwave active system partner: from consulting on the network analysis and planning, down to implementation and after sales service. A 24 months warranty from KBR provides you with additional security.

Safe energy supply
In accordance with the new German Low Voltage Access Directive (NAV), operators must operate their devices so that disturbances of other systems are ruled out. Otherwise, the network operator may interrupt connections without any warning, to prevent disturbances of their facilities or other connections. For this reason, energy-consuming companies and institutions have to check their internal network and ensure that limiting values are maintained. With BLUEWAVE, deviations can, once identified, be reduced so that the value lies within tolerance again. Increased safety for you!
