Dedicated Current Input Module Capable of Supplying Power to Current Sensors

Key Features

  • Clamp connection, up to 500 A AC/DC, automatic sensor identification, easy operation
  • 2 channel input
  • From low to high frequency, wide bandwidth RMS rectifier installed (DC, or 30 Hz to 10 kHz)
  • Monitor instantaneous waveforms without the need to pass through the rectifying circuit
  • High 12-bit A/D resolution
    *Not available for MR8741
Note: This module must be used with the Memory HiCorder. Current sensors are not supplied. Please purchase the appropriate sensors for the intended application.

When Model 9272-05 (200 A), CT6843A, CT6863-05, CT6873, CT6873-01, CT6904A, CT6904A-1, CT6904A-2, CT6904A-3 is used: 20, 40, 100, 200, 400, 1000 A f.s.(f.s. =20div, Choice of 6 ranges)
When Model CT6844A, CT6845A, CT6875A, CT6875A-1, CT6846A, CT6876A(*1), CT6876A-1(*1) is used: 40, 100, 200, 400, 1000, 2000 A f.s.(f.s. =20div, Choice of 6 ranges)
The measurable range is limited by the current sensor connected. Check the specifications of the respective current sensor.
*1: The instrument recognizes this as a 500 A AC/DC sensor is connected; setting the ratio of the scaling function to 2 is required.
Accuracy (with filter 5 Hz ON) Add the accuracy and characteristics of the current sensor used. Measurement accuracy: ±0.65% f.s.
RMS accuracy: ±1% f.s. (DC, 30 Hz to 1 kHz), ±3% f.s. (1 kHz to 10 kHz)
