This product combines the advanced technology of modern digital conversion, fully computer control, automated boost, buck, measurement and protection. human intervention can cared out during the automatic step-up process , mains advantage includes fully electronic ,small sizes and light weight , large-screen LCD ( clear and intuitive ) , printer output test report , easy to use . designed to fully meet the power industry standards .mechanical approach are widely use for modulation and demodulation ultra-low-frequency signals but no standard sine wave , some error of measuring and spark discharge in high-pressure part etc, the products can overcome the shortcoming of above and the following features need to indicate in particular:
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.
How to choose the suitable products for test
Please make sure that the capacitance of test products is below the instrument rated capacitance the waveform will be influence if the capacitance of test products is too small and the instrument can not normally output when it below 0.05µF. 0.1µF capacitor in parallel to auxiliary output . below is capacitance of some instrument for your reference .
