Control accuracy The higher of ±0.5% or less of the rated output or ±1% of the set value
Guaranteed control
range Constant power control: 10 to 100% of the rated power value
*1: This depends on the working condition at your site.
*2: This depends on an input voltage of 187 to 229 VAC. This may depend on the equipment on the input
side.
*3: When a device for preventing unusual electrical discharge is used, the output voltage is limited to
800V.
*4: A low arc energy circuit can be installed as an option. When a device for preventing unusual electrical
discharge is used, only the inverter stops.
