Protection Features
  • Automatic Current Limiting: Once the output current reaches the set current limit, the module automatically switches to constant current operation, preventing any further increase in output current.
  • Overvoltage Protection: If the output voltage exceeds 60-63 VDC, the module automatically stops output to prevent damage to connected equipment.
  • Short-Circuit Protection: During an output short-circuit, the module self-protects to prevent damage. After the fault is cleared, normal operation is automatically restored.
  • Insulation Strength: Input to Chassis: 1600VAC 1 min 5mA (No dielectric breakdown or flashover); Input to Output: 1600VAC 1 min 4mA (No dielectric breakdown or flashover); Output to Chassis: 600VAC 1 min 4mA (No dielectric breakdown or flashover)
Application Scenarios
Ideal for core telecommunication infrastructure and other high-power DC applications:
  • Telecommunication Hubs: Powering central office equipment, large program-controlled switches, and core network nodes requiring high-current 48V power.
  • Industrial Control Systems: Serving as a reliable power source in environments where silent operation and high reliability are critical.
  • Backup Power Systems: Acting as a key rectifier module in large-scale DC backup power systems for critical facilities.
