*2 
For an output voltage of 100 V / 200 V, a load power factor of 1, with respect to 
stepwise change from an output current of 0 A to the maximum current (or its 
reverse). 10% ~ 90% of output voltage 
*3 
For AC mode, at an output voltage of 100 V / 200 V, maximum current, and load power 
factor of 1 and sine wave only.
