• Opbevaring: When not in use for extended periods, store the unit in a dry, dust-free environment within its specified operating temperature range.
• Udskiftning af sikring: If the fuse blows, replace it only with a fuse of the same type and rating as specified on the rear panel. Ensure the unit is disconnected from power before attempting fuse replacement.

9. Fejlfinding

This section addresses common issues you might encounter with the OWON SPE8205 power supply.

• Ingen strøm:
  • Check if the power cord is securely connected to both the unit and the AC outlet.
  • Ensure the rear power switch is in the ON position.
  • Verify the AC outlet is functional.
  • Check the fuse on the rear panel and replace if blown.
• No Output Voltage/aktuel:
  • Ensure the front panel Til/Fra button is pressed to enable the output.
  • Check if OVP or OCP has been triggered. If so, clear the fault and reset the output.
  • Kontroller, at voltage and current settings are not set to zero.
  • Inspect output leads for proper connection and continuity.
• Ustabilt output:
  • Ensure the load is properly connected and stable.
  • Check for loose connections in the output circuitry.
  • Kontroller, at omgivelsestemperaturen er inden for det angivne driftsområde.
• Ventilatorstøj:
  • The intelligent temperature control fan will activate and adjust speed based on internal temperature and load. Increased fan noise under heavy load is normal.
  • Sørg for, at ventilationsåbningerne ikke er blokeret.
