Fluke 52120A Transconductance Amplifier with 10 kHz Frequency 120 A AC Current and 140 ppm Accuracy

The Fluke 52120A is a transconductance amplifier designed to enhance calibration capabilities in laboratory environments. It addresses limitations in output current, accuracy, and drive capability of existing test equipment, making it ideal for calibration laboratories, electrical utilities, and manufacturers of power/energy instrumentation, meters, power quality analyzers, and power converters.

• High-Current Output: Supplies up to 100 A DC and 120 A AC current. With accessory coils, generates 3000 A or 6000 A. Three units in parallel output up to 360 A.
• High-Accuracy Calibration: Accuracy up to 140 ppm for precise calibration of high-current working load devices including power/energy meters, clamp meters, and current transformers.
• Wide Frequency Range: DC to 10 kHz frequency range meets diverse calibration requirements.
• Multiple Operating Modes: Supports parallel operation of 2-3 amplifiers up to 360 A single-phase, or up to 10 amplifiers and 1200 A in standalone mode. Closed-loop mode communicates seamlessly with Fluke Calibration 6105A or 6100B electrical power standards.
