The Fluke Calibration 52120A Transconductance Amplifier supplies
dc current up to 100 amps and ac current up to 120 amps, at
accuracies to 140 ppm. Using accessory coils, it can generate 3,000
or 6,000 amps.
Three 52120As connected in parallel can output up to 360 amps.
Inductive drive capability of 1 mH and compliance voltage of
4.5 volts support a wide range of applications.
