AC Power Input Level
The input of this series instruments is single-phase or three-phase, and the volt-
age level and frequency are as follows.
•
Single-phase(L/N or L/L): 85V～520V, frequency: 50Hz/60Hz.
•
Three-phase(L1/L2/L3): 110V～520V, frequency: 50Hz/60Hz.
The power setting value of this series instruments will be derated when inputting
low-grade voltage. The derating characteristics are detailed in the following ta-
ble. And different model of rated AC current is different, the detailed specifica-
tion refer to the technical specification.
