multiwave active harmonic filter

The advantages

As an active harmonic filter of the newest generation, multiwave Active 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 60 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 power modules are by default equipped with protection type IP20, and thus protected from dust. The standing cabinet version is also splash-proof, according to the protection class IP54.
  

High performance in a confined space
In comparison with other active filters, multiwave active requires little space. In its 50 ampere version, the external dimensions of the device are only 44 x 42 x 22 cm and it weighs less than 44 kg. This makes wall assembly possible without any problems.

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.

Operating comfort

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 Software AHF-Viewer, 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 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 multiwave active, deviations can, once identified, be reduced so that the value lies within tolerance again. Increased safety for you!
