This product combines modern digital frequency conversion high and new technology, adopts microcomputer control, automatic voltage boost, buck, measurement, protection, and manual intervention in the automatic voltage boost process. Because of electronic, so small size and light weight, large screen LCD display, clear and intuitive, printer output test report.

1、 Current and voltage data are obtained directly through high-voltage side sampling, so the data is true and accurate.
2, overvoltage protection: when the output exceeds the set voltage limit value, the instrument will stop the protection, the operation time is less than 20ms.
3, overcurrent protection: designed for dual protection of high and low pressure, the high pressure side can be accurately stopped according to the set value
Protection; When the current on the low voltage side exceeds the rated current, the shutdown protection will be carried out, and the operation time is less than 20ms.
4, the high voltage output protection resistance is designed in the booster body, so there is no need to connect another protection resistance outside.
5, due to the use of high and low voltage closed loop negative feedback control circuit, so the output has no capacity rise effect."
