About This Product

■High precision, low inductance DC/AC current shunt

A40B precision current shunt set includes 14 low inductance coaxial current shunts, adapters and connectors, and a rugged shipping/storage case. The current shunt is designed for currents from 1 mA to 100 A and allows direct measurements of absolute AC and DC currents as well as transfer measurements of AC/DC currents in standard rooms. These shunts' excellent resistance stability, self-heating power coefficient, and low temperature coefficient allow them to directly measure currents from DC to 100 kHz with greater accuracy than traditional commercial shunt technology. Accurate measurements can now be performed in a single step, compared to the conventional complex AC/DC transfer method.

■Features

・Simplify calibration/verification of precision calibrators and current sources ・Supports current from 1mA to 100A ・Can be used from DC to 100 kHz ・14 shunts x1, x2, x5 in the range from 1 mA to 100 A ・Simple direct measurement, no AC/DC transfer required ・Stability within 1 year is typical value ± 5.0 µΩ/Ω or less ・Phase shift is typically ± 0.003º or less at 1 kHz.

■Physical/mechanical parameters

・Shunt value: 1 mA to 20 A ・Weight: 0.7 kg ・Input connector: N type (female) ・Output connector: N type (female) ・Shunt value: 50 A to 100 A ・Weight: 3.4 kg ・Input connector: LC type (female) ・Output connector: N type (female)

■Storage and transportation environment (excluding 1 mA current shunt)

・Temperature to avoid damage: -20 ℃ to 140 ℃ ・Temperature and humidity to maintain performance: 5 to 45 ℃, 15 to 80% RH ・Non-operating altitude: 0 m to 12,000 m
