*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
