Very Low Frequency Tester VLF

Introduction
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. The main advantages include 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.


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.
