5. ترتیب کول

بسته بندي کول: Carefully remove the power supply from its packaging. Retain the packaging for future transport or storage.
ځای په ځای کول: Place the unit on a stable, level surface with adequate ventilation. Ensure there is at least 10 cm (4 inches) of clear space around all sides, especially the rear cooling fan. Avoid placing it near heat sources or in direct sunlight.
د بریښنا پیوستون:
- ډاډ ترلاسه کړئ چې د مخکینۍ پینل بریښنا سویچ په بند حالت کې دی.
- Connect the provided power cord to the AC Power Input on the rear panel.
- Plug the other end of the power cord into a grounded 110V AC outlet.
لومړنۍ کتنه: Before connecting any load, turn the power switch ON. The displays should illuminate. Verify that the voltage and current displays show readings (initially 0V and 0A or a small residual value).

6. عملیاتي لارښوونې

6.1 د ترتیب حجمtage او اوسني محدودیتونه

Ensure the power supply is ON but the output is OFF (Output ON/OFF button).
وګرځوئ والیtagد تنظیم کولو نوب clockwise to increase the voltage or counter-clockwise to decrease it. Observe the Voltage ښودنه.
وګرځوئ د اوسني تنظیم کولو نوب clockwise to increase the current limit or counter-clockwise to decrease it. This sets the maximum current the supply will deliver.
For precise settings, adjust the coarse knob first, then fine-tune with the fine adjustment knob (if available, or use small turns for precision).

۵.۴ د بار سره نښلول

Ensure the power supply output is OFF.
د خپل بار مثبت (+) ټرمینل د بریښنا رسولو سور ټرمینل سره وصل کړئ.
د خپل بار منفي (-) ټرمینل د بریښنا رسولو تور تولید ټرمینل سره وصل کړئ.
Double-check all connections for polarity and security.

6.3 Applying Power to the Load

د مطلوب حجم تنظیم کولو وروستهtage and current limits and connecting the load, press the Output ON/OFF button to enable the output.
Observe the Voltage and Current Displays. The voltage should stabilize at the set value, and the current display will show the actual current drawn by the load (up to the set current limit).
If the load draws more current than the set limit, the power supply will enter constant current (CC) mode, and the current display will show the set limit. The voltage will drop to maintain this current.
To turn off the output, press the Output ON/OFF button بیا

7. ساتنه

پاکول: د پاکولو دمخه د AC ساکټ څخه د بریښنا رسولو قطع کړئ. د بهرنۍ برخې د پاکولو لپاره نرم، وچ ټوکر وکاروئ. د کثافاتو پاکوونکي یا محلولونه مه کاروئ.
وینټیلیشن: Regularly check that the ventilation openings and cooling fan are free from dust and obstructions. Use compressed air to gently clear dust if necessary.
د فیوز بدلول: If the power supply does not turn on, check the fuse located on the rear panel.
- د بریښنا تار قطع کړئ.
- Unscrew the fuse holder cap.
- Replace the fuse with one of the same type and rating (8A).
- کیپ بیرته په خوندي توګه وخورئ.
ذخیره کول: کله چې د اوږدې مودې لپاره په کار نه وي، د بریښنا رسولو په وچ، دوړو څخه پاک چاپیریال کې وساتئ.

8. ستونزه حل کول

ستونزه	احتمالي لامل	د حل لاره
No power, displays off.	Power cord not connected, AC outlet faulty, main power switch off, blown fuse.	Check power cord connection. Test AC outlet. Ensure power switch is ON. Check and replace fuse if necessary (refer to Maintenance section).
د محصول voltage is 0V or lower than set, current display shows set limit (CC mode).	Load resistance is too low, drawing more current than the set limit.	Increase the current limit using the Current Adjustment Knob, or reduce the load. Ensure the load is appropriate for the power supply's rating.
د محصول voltage is unstable or fluctuating.	Loose connections, faulty load, internal issue.	Check all output connections. Test with a different load. If the problem persists, contact customer support.
واحد ډیر ګرمیږي.	Blocked ventilation, excessive load, prolonged operation at high power.	Ensure ventilation openings are clear. Reduce load or operating time. Allow the unit to cool down.
