EfficientSwitch™ is the result of our effective and consistent research

EfficientSwitch™ meets both the highest demand in quality and energy efficiency.

EfficientSwitch™ enables the economical production of first-class, compact electronic control gears.

EfficientSwitch™ endorses the realisation of high-performance power supply units.

PowerUnits Solutions characterise through:

Low-frequency AC Square-Wave Operation

The low-frequency AC-square-wave operation ensures uniform irradiation with virtually no modulation in the flow of electricity. EfficientSwitch™ allows for the precise adjustment of the lamp current frequency between 50Hz and 500Hz. The stimulation of acoustic resonances is inhibited as well as possible, re-ignition peaks are avoided and the optimal plasma arc stability is ensured. The combination of these properties enables the optimal operation of nearly every type of lamp and lamp power.

True Power Control

An integrated microcontroller allows for true lamp power control. This enables the equalisation of voltage variations of different lamp types and ensures exactly reproducible product quality.

High Frequency Ignition

The integrated high frequency ignition box supplies powerful, lamp-protecting impulse packets with up to 4000V sine amplitude. The freely programmable start sequence enables an optimal, quick and smooth lamp start for every type of lamp. The lamp cable length has no negative influence on the ignition characteristics. All in all, the lamp´s service life increases and even so-called "lazy igniter" lamps can be optimally ignited.

DC-Link Capacitor

The integrated energy storage equalises the supply voltage fluctuations. This allows for the interruption-free flow of electricity. No additional power reserve is necessary.

Cyclic Operation

EfficientSwitch™ allows for a true, continuous power control of between 5% and 100% of the radiator power. The transient time is less than 3ms. This guarantees an extremely efficient cyclic operation and low standby consumption.

Electromagnetic Compatibility

EfficientSwitch™ supports the significant reduction of electromagnetic influences. Electromagnetic disturbances and high switching losses are prevented before they can develop.


A microcontroller ensures the optimal parameterisation of all relevant unit properties and lamp properties. The microcontroller assumes all switching operations, control operations and adjusting operations, and guarantees exact data evaluations.
