3. Installation

1. Déballage: Retirez soigneusement le bloc d'alimentation et tous les accessoires de leur emballage. Vérifiez qu'ils ne présentent aucun signe de dommage.
2. Connexion électrique : Connect the provided power cord to the AC input socket on the rear panel of the power supply and then to a suitable AC power outlet. Ensure the voltage selector switch on the rear is set correctly for your region (115V or 230V).
3. Connexions de sortie: Connect the test leads to the output terminals on the front panel. Red terminals are for positive (+) and black terminals are for negative (-). The yellow terminal is for ground.
4. Placement: Place the power supply on a stable, level surface with adequate ventilation around the unit. Do not block the ventilation openings.

4. Mode d'emploi

1. Marche/Arrêt : Press the main power switch on the front panel to turn the unit ON or OFF.
2. Volume de réglagetage and Current (CH1/CH2):
   • Appuyez sur le 'V' (Voltage) or 'A' (Current) button for the desired channel (CH1 or CH2) to select the digit you wish to adjust. The selected digit will blink.
   • Rotate the coarse or fine adjustment knob to change the value of the blinking digit.
   • Répétez jusqu'à obtenir le volume souhaitétage and current limits are set.
3. Activation/désactivation de la sortie : Après avoir réglé le volume souhaitétage and current, press the 'Output' button for the respective channel to enable or disable the output. The indicator light will show the output status.
4. Setting Fixed Voltage (CH3):
   • Press the 'CH3 Voltage' button to cycle through the available fixed voltagOui : 2.5 V, 3.3 V et 5 V.
   • Le vol sélectionnétage will be displayed on the CH3 output.

5. Modes de fonctionnement

The RockSeed RS305D offers three primary operation modes for its main channels (CH1 and CH2):

• Mode Indépendant : In this default mode, CH1 and CH2 operate completely independently. You can set different voltage and current values for each channel, and they will function as two separate power supplies.
• Mode série : To achieve higher voltage output, CH1 and CH2 can be connected in series. In this mode, the total output voltage is the sum of CH1 and CH2 voltages (up to MAX 60V), while the current limit is determined by the lower of the two channel's current settings (up to MAX 5A). Ensure proper wiring for series connection.
• Mode parallèle : For higher current output, CH1 and CH2 can be connected in parallel. In this mode, the total output current is the sum of CH1 and CH2 currents (up to MAX 10A), while the voltage is determined by the lower of the two channel's voltage settings (up to MAX 30V). Ensure proper wiring for parallel connection.

Use the 'INDEP SERIES PARALLEL' switch on the front panel to select the desired mode.

6. Précautions de sécurité

• Veillez toujours à ce que l'alimentation électrique soit branchée sur une prise de courant mise à la terre.
• Vérifiez le volume d'entréetage selector switch on the rear panel matches your local power supply (115V or 230V) before connecting to AC power.
• N’utilisez pas l’alimentation électrique dans un environnement humide ou dégivré.amp environnement.
• Before connecting any device to the power supply, always set the voltage and current limits to appropriate values to prevent damage to the device.
• Ne pas dépasser le vol maximumtage or current ratings of the power supply.
• Assurez une ventilation adéquate pour éviter toute surchauffe. Ne bloquez pas les aérations.
• In case of malfunction, disconnect the power supply immediately and contact customer support. Do not attempt to repair the unit yourself.

7. Entretien

• Nettoyage: Utilisez un chiffon doux et sec pour nettoyer l'extérieur du bloc d'alimentation. N'utilisez pas de produits nettoyants abrasifs ni de solvants.
• Ventilation: Regularly check that the ventilation openings are clear of dust and debris. Use compressed air to clean if necessary.
• Stockage: Lorsqu'elle n'est pas utilisée pendant une période prolongée, rangez le bloc d'alimentation dans un endroit frais et sec, à l'abri de la lumière directe du soleil et des températures extrêmes.

8. Dépannage

• Aucune sortie: Check if the 'Output' button for the respective channel is enabled. Ensure the power supply is turned on and connected to a working AC outlet.
• Lectures incorrectes : Verify that the test leads are securely connected to both the power supply and the load. Check the calibration of any external measurement devices.
• Surcharge/Protection déclenchée : If OVP or OCP indicators light up, it means the output limits have been exceeded. Disconnect the load, reduce the voltage/current settings, and then re-enable the output.
• Surchauffe de l'unité : Ensure adequate ventilation. Check if the cooling fan is operating correctly. Reduce the load if operating at high power for extended periods.
