Specification
•
This function measures the maximum out of the 3-phase currents and converts it into
DC 4~20mA for output, which can be converted back to the original value by a digital meter.
•
20mA Output Settings : 0.5~10A or 5~100A
Note) 1. In the 0.5~10A setting mode the device starts to measure from 0.15A, which means the current 0.15A or less is measured as 0A and the output becomes 4mA.
(0.15A when one> 4mA is being a real measurement)
2. Accuracy at 25°C : : ± 0.15% / ℃
•
During stopping : 4mA
•
Rated setting value or more : 20mA
•
Load : 500Ω or less
Note) The allowable burden of cable must be less than 500Ω.Shielded cables are recommended in consideration of the resistance
of the receiving meter (typically 250Ω) and the line resistance.
