While Digital Fault Recorders (DFRs) can detect transients in 17/20 μs at 60/50 Hz, transient recorders capture disturbances that can peak and decay well within a microsecond. This reference design demonstrates the capturing of transient inputs at up to 1 MHz for DFR and 25 MHz for transient tecorders. Both positive and negative transients (<=2-kV peak) can be captured with varying resolution based on application need (12-bit to 14-bit resolution) and within 10% accuracy using a differential amplifier driving a high-speed converter.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
