China 50kv Very Low Frequency Vlf Hv AC Cable Hipot Testing Instrument, Find details about China AC Hipot Tester High Voltage Testing Instrument, Very Low Frequency Testing Instrument from 50kv Very Low Frequency Vlf Hv AC Cable Hipot Testing Instrument
Very Low Frequency Tester VLF
Introduction
Features
★ Data of current and voltage are obtained directly through the sampling of high-pressure side and it is true and accurate.
★ Over-voltage protection: the instrument will shut down to protection within 20 ms when the output voltage is exceeding limiting values of setting.
★ Over-current protection: design for dual protection of high and low voltage, downtime protection can be accurately set in high-pressure side. it will be shut down for protection and the action time is less than 20 ms when the current of low-voltage sides exceeds reacted current.
★ High-voltage output protection resistor design in the body boost and it is no need to additional outside resistor.
★ Closed-loop negative feedback control circuit of high and low voltage.
