3. Konfigurazioa

1. Despaketatzea: Carefully remove the power supply from its packaging. Inspect for any signs of damage.
2. Lekua: Place the unit on a stable, level surface with adequate ventilation. Ensure there is sufficient space around the unit for airflow, especially around the cooling fan at the rear.
3. Potentzia-konexioa: Connect the provided input power cable to the power socket on the rear panel and then to a standard 110V AC grounded electrical outlet.
4. Hasierako egiaztapena: Ensure the output switch on the front panel is in the OFF position (output disabled). Turn on the main power switch on the rear panel. The LED display should illuminate.

4. Funtzionamendu-argibideak

4.1 Piztu/Itzaltzea

• To power on, flip the main power switch on the rear panel to the 'ON' position.
• To power off, flip the main power switch on the rear panel to the 'OFF' position.

4.2 liburukiatage eta uneko doikuntza

The HY3005B uses encoder adjustment knobs for precise control:

1. Coarse Adjustment: Biratu BOLUMENATAGE or CURRENT knob to adjust the respective value. The display will show the whole number changing.
2. Doikuntza fina: Sakatu VOLTAGE or CURRENT knob briefly. The decimal portion of the display will flash, indicating fine adjustment mode. Rotate the knob to adjust the decimal value. Press the knob again to exit fine adjustment mode.

4.3 Konstante Voltage (CV) eta Korronte Konstanteko (CC) Moduak

• Konstante Voltage (CV) Modua: Irteera bolumena deneantage is stable and below the set current limit, the power supply operates in CV mode. The 'CV' indicator LED will be lit.
• Korronte konstanteko (CC) modua: If the load current reaches the preset current limit, the power supply automatically switches to CC mode. The 'CC' indicator LED will be lit, and the output current will be limited to the set value.

4.4 Irteera-etengailuaren kontrola

The output switch allows you to set voltage and current limits before applying power to your circuit, preventing accidental damage.

4.1. irudia: Close-up of the output switch on the HYELEC HY3005B, designed to prevent damage by allowing voltage and current settings before connecting the load.

1. Ensure the output switch is OFF.
2. Adjust the desired voltage and current limit using their respective knobs.
3. Connect your load to the output terminals.
4. Flip the output switch to the 'ON' position to apply power to the load.

4.5 Datuak gordetzeko funtzioa

To hold a set of voltage and current values, press both the VOLTAGE and CURRENT adjustment knobs simultaneously for 3 seconds. The display will indicate that the values are held. To release the hold, press both knobs simultaneously again for 3 seconds.

5. Segurtasun Ezaugarriak

The HYELEC HY3005B incorporates several safety features to protect both the device and the connected load:

• Gaindituen babesa: Protects against sudden voltage puntak.
• Gainkarga babesa: Limits current to prevent damage to the power supply and load.
• Zirkuitu laburren babesa: Automatically cuts off output in case of a short circuit.
• Temperature Control Fan: An intelligent cooling fan activates when the internal temperature reaches approximately 45°C, ensuring stable operation and preventing overheating.
