Ⅴ: Features of the VLF TEST:
1. Data of current and voltage are obtained directly through the sampling of high-pressure side and it is true and accurate.
2. Over-voltage protection: the instrument will shut down to protection within 20 ms when the output voltage is exceeding limiting values of setting.
3. Over-current protection: design for dual protection of high and low voltage, downtime protection can be accurately set in high-pressure side. Shut down to protection times is within 20 ms when the current of low-voltage sides exceeds reacted current.
4. High-voltage output protection resistor design in the body boost and it is no need to additional outside resistor.
5. Closed-loop negative feedback control circuit of high and low voltage.
