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.
The 52120A is designed for users whose ability to address their calibration workload may be
limited by the output current, accuracy and drive capability of their present test equipment,
