4.2 Conexiune la alimentare

• Ensure the power supply's input voltage setting (if adjustable) matches your local AC supply (110V or 220V). The UDP6721 supports both.
• Connect the provided power cord to the AC input socket on the rear panel of the power supply.
• Conectați celălalt capăt al cablului de alimentare la o priză de curent alternativ cu împământare.

4.3 Connecting a Load

• Before connecting any load, ensure the power supply output is OFF (press the OUTPUT button if necessary).
• Conectați terminalul pozitiv (+) al sarcinii la terminalul roșu de ieșire al sursei de alimentare.
• Conectați terminalul negativ (-) al sarcinii la terminalul negru de ieșire al sursei de alimentare.
• For safety, connect the ground terminal of your load (if applicable) to the green ground terminal of the power supply.
• Ensure all connections are secure to prevent arcing or accidental disconnections.

5. Instrucțiuni de utilizare

5.1 Pornire/Oprire

• Press the main POWER button on the front panel to turn the unit ON. The display will illuminate.
• To turn OFF, press the main POWER button again.

5.2 Reglarea volumuluitage și Curent

• Setarea Voltage: Press the 'V' button. The voltage setting on the display will become active. Rotate the encoder knob to adjust the voltage. A quick turn provides coarse adjustment, while a slow turn allows for fine adjustment. Use the arrow buttons to select specific digits for adjustment.
• Setare curent: Press the 'A' button. The current setting on the display will become active. Rotate the encoder knob to adjust the current limit. Similar to voltage, the knob supports both coarse and fine adjustments.
• Press 'ENTER' to confirm settings or 'ESC' to cancel.

5.3 Control ieșire

• După setarea volumului dorittage and current, press the 'OUTPUT' button to enable the power output to your connected load. The 'ON' indicator on the display will light up.
• To disable the output, press the 'OUTPUT' button again. The 'ON' indicator will turn off.

5.4 Supravoltage Protection (OVP) and Over-Current Protection (OCP)

• Setting OVP: Press the 'OVP' button. Use the encoder knob and arrow buttons to set the maximum allowable output voltage. Dacă volumul de ieșiretage exceeds this limit, the power supply will shut down the output to protect the load.
• Setting OCP: Press the 'OCP' button. Use the encoder knob and arrow buttons to set the maximum allowable output current. If the output current exceeds this limit, the power supply will shut down the output.
• These protection features enhance safety for both the power supply and the connected device.
