6. Упутство за употребу

6.1 Цонстант Волtage (CV) and Constant Current (CC) Mode

Напајање се аутоматски пребацује између константне јачине звукаtage (CV) and Constant Current (CC) modes based on the load. The CV indicator lights up when the output voltage is stable, and the CC indicator lights up when the output current reaches the preset limit.

6.2 Presetting Constant Current Value

  1. Укључите напајање.
  2. Подесите излазну јачину звукаtage to approximately 3V by turning the coarse and fine Voltagе дугмад.
  3. Искључите уређај.
  4. Short the positive (+) and negative (-) output terminals using the provided test leads.
  5. Укључите напајање.
  6. Adjust the Current knobs (coarse and fine) to set the desired current limit in Amperes. The CC indicator will light up.
  7. Turn off the device and remove the shorting leads. The current limit is now set for the entire output voltagе ранге.

6.3 Presetting Constant Voltagе Вредност

  1. Укључите напајање.
  2. Подесите Волtage knobs (coarse and fine) to set the desired output voltage in Volts. The CV indicator will light up.
  3. Искључите уређај.

Note: Once the voltage or current limits are set, avoid adjusting the respective knobs unless a new limit is required.

6.4 Connecting a Load

Након подешавања жељене јачине звукаtage and current limits, connect your load to the output terminals: positive to positive (red) and negative to negative (black). Ensure the power supply is OFF before connecting or disconnecting any load.

Note: If the display shows 'CC' after connecting the load, it indicates that either your preset current limiting value is too low or your load requires more current than the preset limit. Adjust your current and voltagе подешавања у складу са тим.

КСНУМКС. Решавање проблема

Here are some frequently asked questions and their solutions:

Q: When the power is on, the current display shows 0.00 A.
A: This indicates that either no load is connected or the connected load is not drawing current. The DC power supply requires a working load to display current and voltage readings. Connect a functional load to observe current flow.
Q: How to set the current value without connecting a load?
A: To preset the current limit without a load, short the positive (+) and negative (-) output terminals together using the test leads. Then, turn on the power supply and adjust the current knobs to the desired amperage. Once set, turn off the device and remove the shorting leads. The current limit will now be active for any connected load.
Q: How to switch between Constant Voltage (CV) and Constant Current (CC) mode?
A: The power supply automatically switches between CV and CC modes. When the load current is less than the preset current limit, the unit operates in CV mode (CV indicator lit). If the load current reaches or exceeds the preset current limit, the unit automatically switches to CC mode (CC indicator lit) and the output voltage may drop. Adjust the current and voltage settings as needed for your application.
