Dongling DA digital power amplifier - Digital power amplifier family for shaker with modular design, power 0.1 ... 700 kVA

High-power, modular design digital power amplifier for all types of shakers. A device family based on advanced MOSFET technology, which thanks to this technology has excellent technical parameters, very good efficiency, and high reliability. With its backlit LCD display, it is also easy to operate.

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.

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