Power Amplifier DIA-01 Aurora Digital Module For Simulator Application
PAV DIA01 is an optional accessory unit for PONOVO's power amplifiers which can convert analog input signal into digital signal, supporting communication between power amplifier and simulators via AURORA protocol. Via the Aurora port, it communicates with the real-time dynamic system, and then converts the received digital signal into analog signal with output to the power amplifier unit.
The digital signal, converted from the voltage/ current signal by the power amplifier, will be transmitted to the real-time dynamic system. The Aurora will function as the bridge of the closed loop in the system.
