3. Sikkerhedsoplysninger

For at sikre sikker drift og forhindre skader på enheden eller personskade, bedes du overholde følgende sikkerhedsforanstaltninger:

• Tilslut altid strømforsyningen til en jordet stikkontakt.
• Brug ikke enheden i vådt eller damp forhold.
• Ensure proper ventilation; do not block the fan or ventilation openings.
• Åbn ikke c'enasing af strømforsyningen. Overlad al service til kvalificeret personale.
• Use only the specified fuse type (250V fuse) for replacement.
• Bekræft input voltage switch setting (115V/230V) matches your local power supply before connecting.
• Undgå kortslutning af udgangsterminalerne i længere perioder.

4. Opsætning

4.1 Udpakning og inspektion

Carefully remove the power supply from its packaging. Inspect the unit for any signs of physical damage. If any damage is found, do not proceed with setup and contact your supplier.

4.2 Indgang Voltage Valg

Before connecting the power supply to the mains, ensure the input voltage selector switch on the rear panel is set correctly for your region (115V or 230V). Incorrect selection can cause severe damage to the unit.

4.3 Connecting Power and Test Leads

1. Connect the provided power cord to the power input socket on the rear panel and then to a grounded AC outlet.
2. Connect the test leads to the output terminals on the front panel. The red terminal is positive (+), and the black terminal is negative (-).

5. Betjeningsvejledning

5.1 Tænd/sluk

• Tryk på 'POWER'-knappen på frontpanelet for at tænde eller slukke enheden.

5.2 Justering af lydstyrketage og Nuværende

The GA series uses coding potentiometers for precise adjustments:

• Drej 'VOL'-knappenTAGE'-knap til at justere udgangsvolumentage. The set voltage value will be pre-displayed on the screen.
• Rotate the 'CURRENT' knob to adjust the output current limit. The set current value will be pre-displayed on the screen.
• Strømforsyningen fungerer enten i konstant volttage (CV) or Constant Current (CC) mode, automatically switching based on the load and set limits. The display will indicate the active mode (C.V or C.C).

5.3 Digital skærm

The four-window dual-color digital display provides real-time information:

• The upper white digits show the output voltage (V) og strøm (A).
• The lower green digits show the USB output voltage (V) og strøm (A).
• Indicators for Constant Voltage (C.V) and Constant Current (C.C) modes are also displayed.

5.4 USB Fast Charging Function

The integrated USB port supports various fast charging protocols. Connect your compatible device to the USB port for charging. The display will show the USB output voltage og nuværende.

6. Vedligeholdelse

6.1 Rengøring

Ensure the power supply is turned off and disconnected from the mains before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use abrasive cleaners or solvents.

6.2 Ventilation

The unit features a temperature-controlled fan for heat dissipation. Ensure that the ventilation openings on the sides and rear of the unit are not obstructed to maintain optimal performance and lifespan.

6.3 Udskiftning af sikringer

If the power supply fails to turn on, check the fuse located near the power input on the rear panel. To replace the fuse:

1. Tag netledningen ud af stikkontakten.
2. Carefully remove the fuse holder.
3. Replace the blown fuse with a new one of the same type and rating (250V fuse).
4. Reinsert the fuse holder and reconnect the power cord.

ADVARSEL: Only use a 250V fuse for replacement. Using an incorrect fuse can lead to fire or damage to the unit.

7. Fejlfinding

The WANPTEK GA series power supplies are equipped with comprehensive protection features. If you encounter issues, consider the following:

• Ingen strøm: Check the power cord connection, the input voltage selector switch (115V/230V) on the rear, and the fuse (refer to Section 6.3).
• Output Stops: The unit has overload protection. If a short circuit or excessive load is detected, the output will stop. Remove the load, check for faults, and then restart the unit.
• Over Voltage-beskyttelse (OVP): Hvis output voltage exceeds a safe limit, the OVP will activate. Reduce the set voltage or check the load.
• Overstrømsbeskyttelse (OCP): If the output current exceeds the set limit, the OCP will activate. Reduce the load or increase the current limit.
• Overtemperaturbeskyttelse (OTP): If the internal temperature becomes too high, the OTP will activate. Ensure proper ventilation and allow the unit to cool down.
