- Short the positive (+) and negative (-) terminals using the leads.
- Adjust the current to the desired amperage by turning the coarse or fine current knobs. The CC indicator will illuminate.
- Turn off the device and remove the shorting leads.
Note: Do not adjust the current knobs once the current limit has been set as above. Current limiting has now been set for the whole range of output voltages.
5.2. Presetting Constant Voltage Value (CV)

Note: Do not adjust the voltage баскычтары бир жолу томtage жогорудагыдай орнотулган.
5.3. Connecting Your Load
After presetting the desired current and voltage, connect your load (device to be powered) to the output terminals. Ensure positive to positive and negative to negative connections. Then turn on the power supply.
Note: If the display shows CC, either your preset current limiting value is too low or your load requires more voltage же ток. Сиз учурдагы жана көлөмүн тууралоо керекtagжогорудагы кадамдарды колдонуу менен орнотууларды.
5.4. Constant Voltage (CV) and Constant Current (CC) Automatic Conversion
электр энергиясы менен камсыз кылуу милдеттери туруктуу волtage source (CV) as long as the load current is less than the preset current limiting value. If the load current becomes equal to or greater than the preset current limit, the power supply will automatically switch over to the constant current mode (CC), and the voltage will drop. The LED panel will display the CC indicator. If the load current drops below the preset current limit, the power supply returns to constant voltage (CV) режими.

8. Кыйынчылыктарды чечүү (Көп берилүүчү суроолор)
- Q: When power is on, the current display shows 0.000 A. Is it normal?
- A: Yes, it's normal if no load is connected. The power supply measures current only when a load is drawing current. If you connect a load and the current still shows 0.000 A, check your connections and the load itself.
- Q: Is it possible to set the current value without load connecting?
- A: Yes, you can preset the current limit. Turn the voltage knobs fully clockwise, short the output terminals, then adjust the current knobs to your desired limit. The CC indicator will light up. Then remove the shorting leads.
- Q: Can I remember the last settings when turned off and back on again?
- A: The PS305H does not have a memory function for settings. Each time it is powered on, the output will start from 0V and 0A, requiring manual adjustment.
- Q: How to switch between Constant Voltage (CV) жана Туруктуу ток (CC)?
- A: The power supply will automatically switch between CV and CC modes based on the load. If the load current is less than the preset current limit, it operates in CV mode. If the load current reaches or exceeds the preset limit, it switches to CC mode, and the voltage will drop to maintain the current limit.
