VSA-H series switching power amplifier is designed with latest IGBT technique and MCU+DSP+FPGA framework to ensure high power availability and high safety. The single power module is designed as standard 8kVA output with large peak power margin. This feature allows VSA-H series power amplifier to be qualified in working with most kinds of electro-dynamic shakers. Different numbers of module can be combined as per requirement of actual power capacity, without replacing the rack.
Advanced MCU+DSP+FPGA framework is used VSA-H series power amplifier with digital control to ensure high safety of each module and the whole system, to avoid collapse of whole system due to single module failure. VSA-H series power amplifier is also designed based on integrated logical unit, power unit and control unit, with obvious advantages of reliability, flexible configuration, energy saving, and easier maintenance.
