FAE Expert Insights
"The PSI8200 is specifically designed for high-voltage industrial applications where large common-mode voltages are present. The ±60V input range allows direct connection to high-voltage buses without attenuation. I've used this amplifier in motor current monitoring applications where the common-mode voltage swings between 0V and 48V. The 100dB CMRR ensures accurate current measurement despite the high common-mode voltage. The overvoltage protection prevents damage from transients. For best performance, I recommend using balanced source resistances and keeping input traces symmetric. The wide supply range provides flexibility for various industrial systems."
