High-voltage power supply is an important part of image intensifier. Today I will introduce to you how high-voltage power supply is tested.
First of all, you need to prepare tools before inspecting the high-voltage power supply. What tools do you need to prepare? And what do they do? The first is the high-voltage electrostatic machine, which is what we call the high-voltage meter. Its function is to measure the high-voltage power supply. If the value of the high-voltage power supply is too large, you can not use a multimeter. , The last one is a multimeter. If the value is not very large, use a multimeter. The following figure is the scene of the high-voltage power supply inspection site of Sinovel’s NEWHEEK
Newheek mainly produces high-voltage power supplies, image intensifiers, monitors, etc., and the products are exported to home and abroad, and have won unanimous praise. Welcome to consult us.
