Easy to operate: simple wiring, fool operation.
Comprehensive protection: multiple protection (over-voltage protection, over- current
protection at high and low voltage sides), rapid action (when acting)
Room ≤10ms), the instrument is safe and reliable.
Safety and reliability: the controller is connected with the low voltage of the high voltage
generator, with photoelectric control, safe and reliable use.
The high and low voltage closed-loop negative feedback control circuit is adopted,
and the output has no capacity rise effect.
Complete configuration: capacitive touch screen, LCD Chinese character display,
automatic storage, automatic printing.
Large test range: 0.1Hz, 0.05Hz and 0.02hz multi frequency selection, large test range.
Small volume and light weight: it is very convenient for outdoor operation.
