About This Product

The working capacity of power/electrical calibrators is greatly expanded. Fluke Calibration's 52120A transconductance amplifier outputs up to 100 A of direct current and up to 120 A of alternating current with 140 ppm accuracy. Accessory coils can generate 3000 A or 6000 A. Output up to 360 A is possible by connecting three 52120As in parallel. Its 1 mH inductive load drive capability and 4.5 V compliance voltage make it suitable for a wide range of applications.

■Main performance of 52120A

Industry-leading amplification accuracy: 140 ppm AC (when used with 61XXA power standards), 350 ppm AC (when used with DC/LF calibrators), 160 ppm DC (when used with DC/LF calibrators) ・Frequency: up to 10 kHz ・Burden voltage (compliance) 4.5 V @120 A ・Inductive load drive capacity: 1 mH ・Output range: 2 A, 20 A, 120 A Input range: 2 V or 200 mA full scale for 2 A and 20 A output ranges, 1.2 V or 120 mA full scale for 120 A range ・Parallel connection: 2 or 3 units (up to 360 A single phase) ・Accessory coil: 25 turn coil for 3000 A, 50 turn coil for 6000 A ・Communication control using 6105A/6100B power standard (closed loop mode) ・GPIB remote operation
