1. Overview

1. Application

This high-voltage DC power supply is a custom-made special power supply, featuring small size, light weight, high efficiency, and built-in fan for heat dissipation. The maximum operating efficiency is ≥97%. The power module adopts an aluminum shell design, which is lightweight and aesthetic, with a waterproof design. It can be used as a substitute for imported high-voltage DC module power supplies.

2. Product Features

  • DC-DC Isolated Power Converter: Converts the input 1000V DC power into 50V DC power in an isolated manner, with a rated output power of 3000W.
  • High power density, small size, and light weight.
  • Design meets power supply reliability requirements: Input has over/undervoltage protection; output has overvoltage protection, current limiting, short-circuit, and overtemperature protection functions.

  3. After cutting off the power supply, the equipment must be shut down for five minutes to allow sufficient time for the capacitors to discharge before maintenance work can be carried out on the power supply equipment.
  4. Pay attention to safety during use: Avoid touching areas marked with safety warnings or high-voltage signs to prevent electric shock or scalding.
