Opsætning

1. Udpakning: Tag forsigtigt strømforsyningen og alt tilbehør ud af emballagen. Undersøg for tegn på skader.
2. Placering: Place the unit on a stable, level surface with adequate ventilation. Ensure no vents are obstructed.
3. Strømtilslutning:
   • 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.
   • Sæt den anden ende af netledningen i en jordet stikkontakt.
4. Belastningsforbindelse:
   • 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 præcis volumentage 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 webwebsted.

Betjeningsvejledning

1. Tænd: Flip the power switch on the front panel to the ON position. The display will illuminate.
2. Indstilling Voltage og Strøm:
   • Tryk på VSET knap for at indtaste voltage setting mode. The voltage display will flash.
   • Drej på Juster knap to set the desired voltage. Press the knob to move between digits for fine adjustment.
   • Tryk på ISET button to enter current setting mode. The current display will flash.
   • Drej på Juster knap to set the desired current limit. Press the knob to move between digits.
   • Trykke VSET or ISET again to exit setting mode, or wait a few seconds for it to exit automatically.
3. Output kontrol:
   • Efter indstilling af voltage og strøm, tryk på ON/OFF button to enable the output. The "OUT" indicator will light up.
   • Trykke ON/OFF again to disable the output.
4. Memory Functions (M1-M5):
   • Gemmer indstillinger: Indstil den ønskede voltage and current. Press and hold one of the M1-M5 buttons until a beep sounds, indicating the settings are saved.
   • Genkaldelse af indstillinger: Tryk kort på en af M1-M5 buttons to recall the saved settings.
5. Over Voltage Protection (OVP) and Over Current Protection (OCP):
   • Tryk på OVP button to set the over-voltage protection limit. Use the Juster knap.
   • Tryk på OCP button to set the over-current protection limit. Use the Juster knap.
   • These functions automatically shut down the output if the set limits are exceeded, protecting the load and the power supply.
