Dongling SDA digital power amplifier family - Intelligent digital power amplifier family for shaker with modular design, power 0.1 ... 1000 kVA

Intelligent, digital power amplifier family for all types of shakers. The most advanced device family based on IGBT (insulated-gate bipolar transistor) technology, which, thanks to this technology, has even better technical parameters, better efficiency, and significantly higher reliability compared to any similar devices based on MOSFET technology. Its backlit, graphical display makes it very user-friendly.

The built-in safety system monitors temperature, current limit, and vibration amplitude parameters, and in case of a short circuit, it prevents the amplifier from breaking down. Among the special features of the device are outstanding signal-to-noise ratio and minimal distortion factor.

With selectable current limits and voltage ranges, Dongling SDA power amplifiers can be used with all available - any brand - vibration exciters/shakers.
