Note:A box (■) in the above table replaces S (Basic type) or E (EMC filter built-in type) depending on the enclosure.
A box () in the above table replaces GA, GB or C depending on the model.
• Inverter efficiency is calculated using values suitable for each inverter model. The input route mean square
current is calculated based on a power supply capacity of 500 kVA (or 10 times as large as the inverter’s
capacity when the inverter’s capacity exceeds 50 kVA), and a power supply reactance of 5%.
• The input RMS current listed in the above table will vary in inverse proportion to the power supply voltage, such
as 480 VAC.
• The braking current is always constant, independent of braking resistor specifications, including standard and
10%ED models.
