Your KWR103 package typically includes:

  • KORAD KWR103 Programmable DC Power Supply Unit
  • Cable d'alimentació CA
  • Output Test Leads (Red/Black)
  • Cable de comunicació USB
  • Cable de comunicació RS232
  • Software CD (for PC control)
  • Manual d'usuari (aquest document)

Configuració

  1. Desembalatge: Traieu amb cura la font d'alimentació i tots els accessoris de l'embalatge. Inspeccioneu-ho per veure si hi ha signes de danys.
  2. Col·locació: Place the unit on a stable, level surface with adequate ventilation. Ensure no vents are obstructed.
  3. Connexió d'alimentació:
    • Ensure the power switch on the front panel is in the OFF position.
    • Connect the supplied AC power cord to the AC power input on the rear panel.
    • Connecteu l'altre extrem del cable d'alimentació de CA a una presa de corrent amb connexió a terra.
  4. Connexió de càrrega:
    • Connect the red output test lead to the positive (+) terminal and the black output test lead to the negative (-) terminal on the front panel.
    • Connect the other ends of the test leads to your load, ensuring correct polarity. For currents exceeding 10A, use the rear output terminals (if available on your specific model) or thicker gauge wires directly to the internal terminals, following safety guidelines.
    • For precise voltage regulation at the load, especially with long cables or high currents, connect the remote sense wires (SENSE TRIG IN+) from the rear panel directly across your load.
  5. Communication Interface Connection (Optional):
    • USB: Connect the USB cable from the rear panel to your computer.
    • RS232: Connect the RS232 cable from the rear panel to your computer's serial port or a USB-to-serial adapter.
    • LAN: Connect an Ethernet cable from the rear panel to your network router or switch.
    • Install the provided software drivers and control application from the included CD or manufacturer's weblloc.
