This image shows the rear panel of the power supply, featuring the AC power input socket, cooling fan, and fuse holder.

• AC кубаттуулугун киргизүү: Connect the provided AC power cord here.
• Муздатуу желдеткич: Оптималдуу муздатууну камсыз кылуу үчүн ылдамдыкты ички температурага жараша автоматтык түрдө тууралайт.
• Страховка кармагыч: Contains the main protective fuse for the unit.

4. Орнотуу

1. Пакеттен чыгаруу: Carefully remove the power supply from its packaging. Inspect for any signs of damage during transit.
2. Жайгашкан жери: Place the unit on a stable, level surface with adequate ventilation. Ensure there is sufficient space around the cooling fan at the rear.
3. Кубат туташуу:
   • Алдыңкы панелдеги кубат которгучу "OFF" абалында экенин текшериңиз.
   • Connect the provided AC power cord to the AC power input socket on the rear panel.
   • Plug the other end of the AC power cord into a grounded 220V AC wall outlet.
4. Алгачкы текшерүү: Before connecting any load, turn on the power supply. The digital displays should illuminate, showing default voltage жана учурдагы окуулар.

5. Иштөө нускамалары

5.1 Күйгүзүү/өчүрүү

• Күйгүзүү үчүн: Flip the power switch on the front panel to the "ON" position. The displays will light up.
• Өчүрүү үчүн: Flip the power switch to the "OFF" position. The displays will turn off.

5.2 Adjusting Voltage

1. Ensure no load is connected or the load can safely handle the maximum voltage.
2. колдонуу Coarse Voltage үндү жөндөө үчүн баскычtage close to your desired value.
3. колдонуу Fine Voltage knob to precisely adjust the voltage to the exact required value.
4. Томtage display will show the current output voltage.

5.3 Adjusting Current Limit

The current adjustment knobs set the maximum current the power supply will deliver. This is crucial for protecting sensitive circuits.

1. Method 1 (Without Load):
   • Каалаган чыгаруу көлөмүн коюңузtage (мисалы, 5V).
   • Short-circuit the output terminals (connect positive to negative with a short, thick wire for a brief moment). The CC indicator will light up, and the current display will show the maximum current.
   • колдонуу Coarse Current жана Fine Current knobs to set the desired current limit.
   • Remove the short circuit. The power supply will return to constant voltage режими.
2. Method 2 (With Load):
   • Connect your load.
   • Томду коюңузtage to your desired value.
   • Adjust the current limit knobs. If the load draws less than the set limit, the unit operates in CV mode. If the load attempts to draw more than the set limit, the unit switches to CC mode, and the output voltage will drop to maintain the set current.

5.4 Constant Voltage (CV) жана туруктуу ток (CC) режимдери

• Constant Voltage (CV) режими: When the load current is below the preset current limit, the power supply maintains a constant output voltage as set by the voltage knobs. The CV indicator will be lit.
• Туруктуу ток (ТК) режими: When the load current reaches the preset current limit, the power supply automatically switches to constant current mode. The output voltage will decrease to prevent the current from exceeding the set limit. The CC indicator will be lit.

5.5 Коргоо функциялары

The power supply incorporates several protection mechanisms:

• Ашык-томtage Коргоо (OVP): Protects the load from excessive voltage.
• Short Circuit Protection (OCP): Limits current in case of a short circuit at the output.
• Over-Temperature Protection (OTP): Shuts down the unit if internal temperature exceeds safe limits.

6. Техникалык тейлөө

• Тазалоо: Тазалоодон мурун электр кубатын розеткадан сууруп алыңыз. Сыртын сүртүү үчүн жумшак, кургак чүпүрөктү колдонуңуз. Абразивдүү тазалоочу каражаттарды же эриткичтерди колдонбоңуз.
• Вентиляция: Regularly check that the cooling fan and vents are free from dust and obstructions to ensure proper airflow.
• Сактагычты алмаштыруу: If the unit does not power on, check the fuse located on the rear panel. Replace it only with a fuse of the same type and rating (e.g., 3.15A).
• Сактагыч: Узак мөөнөткө колдонулбаганда, кубат менен камсыздоону салкын, кургак жерде, тике күн нурунан жана өтө температурадан алыс сактаңыз.
