Brief Introduction
The voltage of the high-voltage DC power supply is within 0-50KV, and the power can reach 400kW.
The voltage and current can be continuously adjusted, and it can work continuously and stably at full load for a long time.
This power supply can be used in high-tech tests in national defense, gas discharge, and test aging of high-voltage electron tubes, and can also be used in test aging of other electronic components.
Since the output voltage of this power supply is relatively high, unless otherwise specified, the output negative terminal is generally connected to the chassis, that is, the ground wire, to ensure the personal safety of the user.
