Description


Reduce Harmonics - save up to 30% energy costs.

The REOWAVE®passive filters harmonics caused by the B6 circuit (thyristor, diode bridge, etc.) and motor drives. The supply network is relieved by compensating the harmonics reactive power. This enables cost savings in material selection and energy consumption. Starting currents and current peaks are greatly attenuated.

This increases the service life and reliability of electrical systems.  Due to the compact and ready-build an easy installation is possible.

The REOWAVE®passive helps to comply with international power quality standards IEEE 519 or EN 61000-3.

REOWAVE®passive

Save money with less reactive power

In the course of rising energy costs and growing CO2 emissions minimizing losses in the transmission grid gains more and more importance. An important factor are the reactive currents. These currents do not contribute to the effective power, but stress all components in the current path and cause additional losses to the ohmic resistance component of the lead. Reactive currents are, for example, harmonics caused by the usage of frequency.

However, reducing the energy efficiency is not only a burden on the environment because more energy is consumed for a steady performance - at the same time the costs increase for the operator of the installations, as they have to pay the reactive power.

Mains chokes, DC chokes or Harmonic filter of REO filter unwanted harmonics and help to counteract the resulting reactive current. Thus, the reactive power is diminished, the energy requirement and the running costs are reduced.

NEW! Overcurrent signal to monitor the filter effect

The REO overcurrent indication signals at anytime your energy efficiency.
You can track your power consumption:

  • GREEN = power consumption about 80% (based on the rated current of the filter)
  • YELLOW= power consumption about 100% (based on the rated current of the filter)
  • RED= power consumption above 105% (based on the rated current of the filter)

 

 

Temperature monitoring

Bespoke electronics monitor the operating temperature of the inductive
components, used within the filter. If these exceed the safe operating
temperature, a potential-free contact will indicate this.

Disconnection of the fi lter function in case of failure

If an overtemperature condition is discovered the mains is automatically
disconnected after a pre-determined delay in order to avoid permanent system damage.
All error messages are reset when the power is again returned to the rated
operating condition.

Optionally with corresponding plugs and sockets for immediate use without large
installations, - like that, immediate beginning of the savings !
