The universal REVCON Front End - RFE is used as a supply and regen unit for one or multiple variable frequency drives. Compared to the brake chopper, the RFE is using regenerative braking instead of converting the energy into heat. The energy is fed into the mains supply through a unique inverting procedure and creates only a small DC bus voltage raise.

Typical applications are engine test stands, escalators, hydroelectric power plants, cranes and many more.

The patented switching principle of the REVCON Front End is unique and guarantees an extremely high product lifetime and very low losses. Due to the high efficiency, the design of the unit is extremely compact. Due to its unique control, no programming or parameter setting is required. Plug & Play! This patented principle reach an efficiency of up to >99% and therefore the produced power losses are up to 75% less than those produced by comparable solutions, so called Active Front Ends, AFE.

All our front ends are available for all low voltage 3-phase supplies and covers power from 7kW up to 250kW, with an open end in parallel setup! Looking forward to meet you at our Stand!

The active REVCON Harmonic Filter – RHF-Active is a high efficient active harmonic filter used to avoid mains distortion caused by any non-linear loads such as variable frequency drives. Revcon offers 3-level IGBT based filter, but also a unique Silicon Carbide (SiC) based Active Filter!

Ideally, all loads and sources have a pure sinusoidal current waveform. But unfortunately the true waveform of most equipment is very different. Nonlinear loads as for example the diode input bridge of a 6-pulse drive are causing a distortion of the mains voltage. This distortion typically evaluated by the Total Harmonic Distortion THD, evaluates frequencies from the second up to the 50th harmonic. In a 50Hz Network this is the area between 100Hz and 2,5kHz.

The impact of the voltage distortion is diverse, and the most typical effect is overheat of transformer and PFC applications (Capacitor banks). An underestimated impact of harmonic distortion is the significantly reduced lifetime expectation of electrical and mechanical equipment.

The active Revcon Harmonic Filter reduces the THDi of nonlinear loads and sources to typically below 5% (fully scalable). This is necessary to reach various standards and recommendations, such as IEEE 519-2014. Due to the high switching frequency of the RHF-Active, the compensation of high order harmonics is very efficient and accurate. Due to its unique circuit, the RHF-Active is extremely efficient which allows for a very compact design.

All RHF-Active can be used as 3P4W or 3P3W for 380-415V systems (further voltage levels coming soon!). Unlimited current possibilities due to open end in parallel setup! Looking forward to meet you at our Stand!

The REVCON Step down (RSD) and REVCON Step Up are DC-DC converter, transforming a high or low DC voltage into lower or higher DC voltage output. The DC Converter are available as a current or voltage controlled system, and optional internal rectifier allows for AC feed.

The DC output and input voltage is freely selectable within the limits of the low voltage directive. The units are available from 15A up to 500A.

Looking forward to your visit!

The REVCON Harmonic Filter – RHF is a high efficient two-stage Harmonic Filter used to avoid mains distortion caused by non-linear loads such as variable frequency drives.

Ideally all loads and sources have a pure sinusoidal current waveform. But unfortunately the true waveform of most equipment is very different. Nonlinear loads like for example the diode input bridge of a 6-pulse drive are causing a distortion of the mains voltage. This distortion typically evaluated by the Total Harmonic Distortion THD, evaluates frequencies from the 2nd up to the 50th harmonic. In a 50Hz Network this is the area between 100Hz and 2,5kHz.

The impact of the voltage distortion is diverse, and the most typical effect is overheat of transformer and PFC applications (Capacitor banks). An underestimated impact of harmonic distortion is the significantly reduced lifetime expectation of electrical and mechanical equipment.

The Revcon Harmonic Filter reduces the THDi of nonlinear loads and sources to significantly below 5% (optional 10%) even under realistic circumstances including imbalance and pre-distortion. This is necessary to reach various standards and recommendations, such as IEEE 519-2014. Typically simple passive harmonic filters are tuned to 250Hz and therefore focus mainly on the 5th harmonic. Due to its unique filter circuit, the RHF works like a bandwidth filter and reduces all harmonics up to ~60. At last but least: This patented filter circuit reach an efficiency of up to 99.5% and therefore the produced power losses are up to 75% less than those produced by comparable solutions.

All our filters are available for all low voltage 3-phase supplies and covers power from 1kW up to 800kW, with an open end in parallel setup! Looking forward to meet you at our Stand!
