Metal 3D printer Electron beam welding OEM customization available SPECIFICATION OF INPUT PART Rated power of high voltage power supply High-voltage power supply output part (optional) 1. Output DC high voltage: 0～-Maximum voltage is continuously adjustable 2. Output current: 0-maximum current continuously adjustable 3. High voltage control: the user set DC 0~10V voltage signal =0~maximum voltage 4. High-voltage display: The power supply has a high-voltage actual value measurement channel and outputs a 0~10V signal. This signal corresponds to 0~maximum voltage and is input to the user as a high-voltage feedback signal. 5. Line regulation: input voltage change 10%, high voltage output change ≤0.01% 6. Static load regulation: between load current 0-maximum current, high voltage output change ≤0.01% 7. Dynamic load regulation: load current 0-maximum current step change, high voltage output change ≤0.01% 8. Output voltage ripple: ≤0.1% 9. Transient response: After a short circuit or discharge, it will return to the set voltage within 50ms 10. Temperature coefficient: 25ppm/℃ 11. Stability: After preheating for 1 hour, less than 0.1% per hour. Grid bias power output 2. Grid bias control adjustment: 2 control methods (open-loop control and closed-loop control, set the switch on the high-voltage power supply body or remote control interface) a) In open loop control: user output DC 0~10V voltage signal corresponding to grid bias DC 0~-2000V b) In closed-loop control: automatically adjust the grid bias voltage to achieve the purpose of stabilizing the beam current, and the user output signal voltage is DC 0~3V, corresponding to the beam current 0-66mA
