*1 ( 200 ～ 220 ) ±10%, 3 phase AC input, 60% of the rated power output for 12Kw and above models.
*2 Under the output frequency of 50Hz/60Hz, the maximum CF is 5 without exceeding the peak current; under the condition of full current and full
power, the maximum CF is 3.
*3 When frequency <150Hz, the minimum current for test need to be 1%F.S. frequency >150Hz, the minimum current for test need to be 3%F.S.
*4When loopSpeed Low is low ， it can better complied DUT's characteristics ； When LoopSpeed is High ， the dynamic response time is
*5 Frequency <150Hz, the specification is meet.
*6 In the rectifier load mode, the setting range of phase Angle is related to CF. The larger CF is, the larger the range of phase Angle can be set.
