Fluke Calibration 52120A Transconductance Amplifier Enables Accurate Calibration of a Broad High-Current Workload at Full Current Range

EVERETT, Wash. -- Fluke(® )Calibration introduces the 52120A Transconductance Amplifier, which expands calibration capabilities to a broad array of power and energy meters, clamp meters, current transformers and Rogowski coils (e.g. Fluke i6000 iFlex) up to 6000 A. Its industry-leading amplifier accuracy ensures precise calibration of devices.

The 52120A Transconductance Amplifier:

-- Supplies dc current to 100 A and ac current up to 120 A at accuracies to 140 ppm
-- Generates 3000 or 6000 A when using accessory coils
-- Can output up to 360 A when three amplifiers are connected in parallel
-- Has inductive drive capability of 1 mH and compliance voltage of 4.5 V

The 52120A is designed for users whose ability to address their high-current calibration workload is limited by the output current, accuracy and drive capacity of their current test equipment. This includes calibration professionals in a calibration/standards lab or electrical utility, manufacturers of power/energy instrumentation and meters, as well as users of electrical test and measurement equipment.

The amplifier operates with any calibrator, signal generator or power supply capable of sourcing 2 V or 200 mA dc or ac, including the Fluke 5080A, 5500 and 5520 Series Multi-Product Calibrators, 5700 Series Multifunction Calibrators, and the 9100 Universal Calibration System. It can also operate in closed-loop mode, seamlessly communicating with Fluke Calibration 610X Electrical Power Standard to deliver enhanced 52120A accuracy.
