Specifications of Input, Output, and Measurement
Maximum rated current*
1
30 A range: 30 A rms
5 A range: 5 A rms
0.5 A range: 0.5 A rms
Derating is needed as input frequency
increases.
See “Frequency derating curve” (p. 78) in “3.4
Typical characteristics.”
Specified for currents of DC and sine wave
Maximum peak current
30 A range: ±50 A peak
(maximum duration of input: 2 s*
2
)
5 A range: ±7.5 A peak
0.5 A range: ±0.75 A peak (less than 10 MHz)
±0.3 A peak (10 MHz or more)
Noise 75 µA rms or less (Typical: 60 µA rms)
(For only the probe with the 0.5 A range,
connected with a measuring instrument that has
a frequency band of 20 MHz)
Input impedance
See “Input impedance” (p. 80) in “3.4 Typical
characteristics.”
*1. Depending on the ambient temperature and measurement
conditions, internal overheating can result in an overload
condition, limiting the maximum rated current lower than those
specified here.
*2. The device requires to cool down for 10 times the length of time
the current was inputted.
