*1
200-240V, 3 phase AC input, power is 60% of the rated.
*2
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
When loopSpeed Low is low
，
it can better complied
DUT’s characteristics
；
When LoopSpeed is High
，
the dynamic
response time is faster.
*4
The dynamic response time test condition is: DC high-speed mode, and the capacitance of the DUT to be less than
10uF
All the above parameters are subject to change without prior notice from ITECH.
