Description:
This product is used for USB interface pressure test. It is a test instrument for sustainable output pulse voltage based on the switch boost structure. The input energy is taken from the output of the USB interface itself (5V 1A or higher), so there is no need to charge it. But it requires the output capability of the USB interface: the output voltage is 5V, the error is no more than ±20%, and the current output is not less than 1A. Please follow the instruction, or the product will malfunction.
This product may emit a slight sound during operation. The sound originates from the current sound generated by the discharge control element.
Using:
- This product is plugged into the required USB interface. It will automatically discharge. You only need to record the data you need to measure with other measuring instruments while it is discharging. However, it is recommended that the continuous working time is not more than 10s. In the limit case, it does not exceed 30s. Because the product has many components placed on a very small area, the thermal effect is obvious. Please do not exceed the above working time when there is no good heat dissipation (forced cooling).
- This product is only suitable for computer motherboards, industrial control equipment, medical equipment, test of measuring instruments and other discrete power supply mainframes or their options. Its interface is USB TYPE-A. Not for micro USB, USB type C, Lighting, and other pin-intensive interface, for it may damage the item itself by breaking down the air between the pins.
Appearance & Size:
- Its PCB board is compatible with the shell of universal U disk most of which can be got easily.
Performance:
- Required input 5V/1A.
- The output is a -500V pulse with an average frequency of 4Hz (number of discharges per second).
