Yes, this is currently still possible. An overview of our most popular models or their successor models can be found under “Products”. In addition, all models can be replaced by our new WaveStart line.

The further development of our VSA with VDR resistors and thermal fuses protects against intensifying mains pollution, such as transient overvoltages (Burst EN 61000-4-4, Surge EN 61000-4-5). Installation and installation sizes remain identical to the respective predecessor models.

For resellers we offer special conditions and graduated prices. We will be happy to submit you an offer without obligation.

Yes, because the WaveStart was designed with the rapidly growing stand-alone market in mind. Due to the optimized start in the nominal current and due to its mains purity, the WaveStart can also be used in energetically unstable systems due to its robustness.

The VSA is a kind of current brake that reduces the starting current, in particular the inrush current. In this way, the VSA breaks the current peaks, giving the power grid more reserves.

This depends on the degree of interference. In principle, a heat pump operator has the right to a clean network. If this is externally polluted (e.g. by an industrial area), a sine filter can be installed on site in the connection point.

In case of pressure differences, the WaveStart still ensures the start of the air conditioning compressor, but not optimized. For this reason, we recommend pressure equalization during the entire start-up phase.

We combine the best of both technologies in the WaveStart: we switch and transmit absolutely interference-free in the analog power section and specifically use digital technology in the control section to guarantee functions such as current and voltage monitoring.
