4.1 Негизги операция

1. Күйгүзүү: Press the Power Switch to turn on the unit. The LED display will illuminate.
2. Setting Voltage: колдонуу Тtage баскычы (орой) to set the integer part of the desired voltagе жана Тtage баскычы (жакшы) to set the decimal part. The display resolution is up to 0.01V.
3. Учурдагы орнотуу: колдонуу Учурдагы баскыч (орой) to set the integer part of the desired current limit and the Учурдагы баскыч (жакшы) to set the decimal part. The display resolution is up to 0.001A.
4. Чыгууну башкаруу: басыңыз Output Control Button to enable or disable the main output. This allows you to adjust settings without disconnecting the load or turning off the power.
5. OPN Function: The OPN function allows the unit to output voltage and current as soon as the power switch is turned on, without needing to press the "OUTPUT" button. Consult the included instruction manual for details on enabling/disabling this feature.

4.2 USB заряддоо функциясы

The power supply features dedicated USB-A and USB-C ports, both supporting 20W fast charging. These are convenient for charging smartphones or powering small electronic modules like Arduino UNO or Raspberry Pi.

5. Техникалык тейлөө

• Тазалоо: Regularly clean the exterior of the unit with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Вентиляция: Ensure the cooling fan and ventilation slots are free from dust and obstructions to maintain proper airflow and prevent overheating.
• Сактагыч: Store the power supply in a cool, dry place away from direct sunlight and excessive humidity when not in use.

6. Кыйынчылыктарды

• Кубат жок: Check the power cord connection and ensure the Input Selectable Switch is set correctly for your region's voltage. Verify the fuse in the Fuse Box.
• No Output Voltage/Current: Ensure the Output Control Button is pressed (output ON). Check if the OCP Status LED is illuminated, indicating over-current protection.
• Over-Current Protection (OCP) Activation: If the OCP LED illuminates and output stops, it indicates that the current drawn by the load has exceeded the set current limit. Reduce the load or increase the current limit.
• Slight Voltage Айырмачылык: Minor variations between the displayed voltage and an external multimeter reading can occur. This is often within acceptable tolerances for bench power supplies. If precise voltage is critical, use an external calibrated multimeter for verification and adjust the output accordingly.
• Delayed Output Shutdown: Due to internal capacitors, the output voltage may take a second or two to fully discharge and reach zero after the output button is turned off. This is normal operation.
