Introduction
TH0240, a series of I/V high-precision AC/DC current transfer standard, are divided into A, B, C, D four versions according to the accuracy.
TH0230 can work in the DC, 10HZ~5kHz frequency range (3dB signal bandwidth ≥100kHz), converting 200A ~ 10kA nominal current into 1V small voltage.
Best DC ratio measurement accuracy: 5 ppm(TH0240D), Best AC ratio measurement accuracy: 100 ppm(TH0240D), supporting positive and negative current measurement.
DC current multi-lap zero adjustment potentiometer and locking device, primary input and secondary output have good electrical isolation, high common mode rejection ratio (CMRR).
l It is convenient to be connected into the large current loop with threading structure. The secondary output can be equipped with high-precision voltmeter to achieve high-precise measurement of current.
It is suitable for calibration of AC-DC high current source/meter (such as calibrator for clamp-meter), current sensor/transformer, electric welder, micro-ohmmeter and other occasions where current needs to be measured.
TH0230 can be used with broadband AC/DC V/V voltage divider, dual-channel voltage vector analyzer to set up high-precision AC/DC power/energy measurement system.
