2. Sikkerhedsinstruktioner
Always adhere to the following safety precautions to prevent electric shock, fire, or damage to the device:
- Ensure the power supply is connected to a grounded outlet with the correct voltage (AC 230V).
- Brug ikke enheden i vådt eller damp forhold.
- Åbn ikke c'enasing; der er ingen dele indeni, som brugeren kan servicere. Overlad al service til kvalificeret personale.
- Undgå at kortslutte udgangsterminalerne.
- Ensure proper ventilation; do not block the ventilation openings.
- Disconnect the power cord before cleaning or moving the unit.
- Use only the specified fuse type (F5A250VAC).

3.1 Frontpanel
Figur 2: Detaljeret view af frontpanelet.
- Digital skærm: Shows real-time output voltage (V) og strøm (A).
- Voltage Adjustment Knobs (VOLT):
- Grov: For large adjustments of output voltage.
- Bøde: For precise adjustments of output voltage.
- Current Adjustment Knobs (CURR):
- Grov: For large adjustments of output current limit.
- Bøde: For precise adjustments of output current limit.
- C.V. (Constant Voltage) Indikator: Illuminates when the unit is operating in constant voltage -tilstand.
- C.C. (Constant Current) Indicator: Illuminates when the unit is operating in constant current mode.
- Afbryderen: Slår enheden til/fra.
- Udgangsterminaler: Standard 4mm banana plug sockets for positive (red), negative (black), and ground (green/yellow) connections.
3.2 Bagpanel
Figur 3: Detaljeret view of the rear panel.
- Køleventilator: Provides necessary airflow to dissipate heat.
- AC strømindgang: IEC C14 connector for the power cord.
- Sikringsholder: Contains the main protective fuse (F5A250VAC).
4. Opsætning
- Udpakning: Carefully remove the power supply from its packaging. Inspect for any signs of damage during transit. Retain the packaging for future transport or storage.
- Placering: Place the unit on a stable, level surface. Ensure there is adequate space around the unit (at least 10 cm on all sides) for proper ventilation, especially around the rear cooling fan. Avoid placing it near heat sources or in direct sunlight.
- Strømtilslutning: Connect the supplied AC power cord to the AC power input on the rear panel of the power supply and then to a grounded AC 230V wall outlet.
- Indledende kontrol: Before connecting any load, turn on the power supply using the front panel power switch. The digital display should illuminate, showing voltage og aktuelle aflæsninger.
5. Betjeningsvejledning
5.1 Tænd og sluk
- To turn on, press the power switch on the front panel to the 'ON' (I) position.
- To turn off, press the power switch to the 'OFF' (O) position.
5.2 Justering af lydstyrketage og Nuværende
- Indstilling Voltage: Rotate the 'VOLT Coarse' knob to set the approximate desired voltage. Use the 'VOLT Fine' knob for precise adjustments. Observe the voltage reading on the digital display.
- Indstilling af strømgrænse: Rotate the 'CURR Coarse' knob to set the approximate maximum current limit. Use the 'CURR Fine' knob for precise adjustments. This setting determines the maximum current the power supply will deliver before switching to Constant Current (C.C.) mode.
- Understanding CV/CC Modes:
- Constant Voltage (C.V.): When the load resistance is high enough that the current drawn is less than the set current limit, the power supply operates in C.V. mode, maintaining the set voltage. The C.V. indicator will be lit.
- Constant Current (C.C.): When the load resistance is low, causing the current drawn to reach the set current limit, the power supply switches to C.C. mode. The output voltage will drop to maintain the set current. The C.C. indicator will be lit.
5.3 Connecting a Load
- Sørg for, at strømforsyningen er slukket, før du tilslutter nogen belastning.
- Connect the positive (+) terminal of your load to the red output terminal of the power supply.
- Connect the negative (-) terminal of your load to the black output terminal of the power supply.
- If your load requires grounding, connect its ground terminal to the green/yellow output terminal of the power supply.
- After connecting the load, turn on the power supply. Adjust voltage and current as required for your application.
6. Vedligeholdelse
- Rensning: Afbryd strømforsyningen fra lysnettet før rengøring. Brug en blød, tør klud til at tørre ydersiden af. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- Ventilation: Regularly check that the ventilation openings and cooling fan are free from dust and debris. Use compressed air to clear any blockages if necessary.
- Udskiftning af sikring: If the unit fails to power on, the fuse may need replacement. Disconnect the power cord, locate the fuse holder on the rear panel, and replace the fuse with one of the identical type and rating (F5A250VAC).
- Opbevaring: Når strømforsyningen ikke er i brug i længere perioder, skal den opbevares køligt og tørt, væk fra direkte sollys og ekstreme temperaturer.
7. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Enheden tænder ikke. | No power from outlet; Power cord loose; Blown fuse. | Check wall outlet; Ensure power cord is securely connected; Replace fuse (F5A250VAC). |
| Ingen output voltage/strøm. | Udgangsterminaler ikke tilsluttet; Voltage/current knobs set to zero; Unit in C.C. mode with low current limit. | Verify load connections; Adjust voltage and current knobs; Increase current limit or check load resistance. |
