Built-in USB/CAN/LAN/Digital IO interface, optional GPIB /
Analog&RS232
*1
supports single phase 220V input, power cord connecting refer to manual.
*2
According to the output frequency, the output voltage will be reduced, the rated voltage can be out within 1.4K, the
maximumoutput voltage at 2KHz is 253VRMS and 2.4KHz is 211VRMS.
*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
