Precise current transducers

Precise current transducers are dedicated for electronic DC, AC, pulse voltage measurements, operating in the range from 12.5 A to even 24 kA. They are available in versions for a PCB and with a hole for the cable. Excellent linearity throughout the range means that they can be successfully used in laboratory, medical and any other applications where high measurement precision is needed.

Notes:
ⁱ⁾ Linearity measured at DC
^j)Bandwidth is measured under small signal conditions - amplitude of 0.5% I _PN (DC)
^k) All ppm figures refer to V_OUT or I_OUT@ I_PN(DC) except for ITL 900-T where it refers to I_OUT = 600 mA
^l)Electrical offset current + self magnetization + effect of earth magnetic field @ T_A +25 °C
^m) Small signal 5% of I_PN(DC), 32 A_RMS
ⁿ⁾ Small signal40A _RMS
^o) Bandwidth is measured under small signal conditions - amplitude of 1% I_PN(DC)
