*1 ( 200～220 ) ±10% input, the power is 60% of the rated.
*2
*3 According to the output frequency, the output voltage will be reduced, the rated voltage can be out within 1.4K, the maximum output
voltage at 2KHz is 250.76Vrms and 2.4KHz is 208.97Vrms.
*3 Under the output frequency of 50Hz/60Hz, the maximum CF is 6 without exceeding the peak current; under the condition of full current
and full power, the maximum CF is 3.
*4
When loopSpeed Low is low，it can better complied DUT's characteristics； When LoopSpeed is High，the dynamic response time is
faster.
*5 30kW and above models need to be tested in sense remote measurement mode.
*6 Test condition: Pure resistive load, full power condition.
*7
The dynamic response time test condition is: DC high-speed mode, and the capacitance of the DUT to be less than 10uF
*8
Under the output frequency of 50Hz/60Hz, the maximum CF is 6 without exceeding the peak current; under the condition of full current
and full power, the maximum CF is 3.
*9 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.
*10 When loopSpeed Low is low，it can better complied DUT's characteristics； When LoopSpeed is High，the dynamic response time is
faster.
*11
Test conditions: Test current >10% F.S., test frequency <150Hz.
*12 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.
*13 1% F.S. for frequencies 150 Hz and less, 5% F.S. for frequencies greater than 150 Hz.
*14 Test conditions: 380V /50Hz AC input, 350Vrms/50Hz/full power output.
