• Infrared Receiver Module: Connect an infrared receiver module for efficient and fast remote control.

3. Istruzzjonijiet Operattivi

The SK120X features an intuitive UI for monitoring and setting parameters.

3.1. Product UI Function Details

When the power supply is ON, the main UI displays output voltage (CV), output current (A), and output power (W). The encoder button can be pressed to toggle through additional displays such as capacity (Ah), energy (Wh), time (h), and temperature (°C).

When the power is OFF, the set voltage (CV) and set current (CC) are displayed alternately. If an external temperature probe is connected, its temperature will also be displayed.

3.2. UI Parameter Settings

Biex tidħol fil-menu tas-settings:

1. Agħfas u żomm il- SET button on the main interface.
2. The first parameter displayed allows you to select the data group (e.g., Cxd-x).
3. Agħfas fil-qosor VSET biex tagħżel il-parametru li jmiss.
4. Agħfas fil-qosor ISET biex tagħżel il-parametru preċedenti.
5. To adjust a parameter value, rotate the encoder.
6. After completing your settings, press and hold the ISET/SW/encoder button to exit the settings interface.

Il-parametri disponibbli jinkludu:

• Cxd-x: Select data group.
• SET CV: Issettja l-output voltage.
• SET CC: Set output current.
• LVP: L-input undervoltage protection (default 5.5V).
• OVP: Ħruġ żejjedtage protection (default 38V).
• OCP: Output overcurrent protection (default 6.2A).
• OPP: Output overpower protection (default 125W).
• OAH: Overcapacity protection (default OFF).
• OPH: Overenergy protection (default OFF).
• OHP: Overtime protection (default OFF).
• OTP: Overtemperature protection (default 95°C).
• ETP: External overtemperature protection (default OFF).
• PON: Automatically enabled during power-on (default OFF).

4. Manutenzjoni

No specific maintenance procedures are provided for this product. It is recommended to keep the device clean and free from dust. Ensure proper ventilation to prevent overheating, especially during high-power operation.

5 Issolvi l-problemi

The SK120X is equipped with several built-in protection features to ensure safe operation and prevent damage. If the device unexpectedly shuts down or does not operate as expected, consider the following:

• Input Undervoltage Protection (LVP): Jekk l-input voltage drops below 4.7V (or the set LVP value), the device may reduce output power or shut down. Ensure your input power source is stable and provides sufficient voltage (recommended >7V).
• Output Overvoltage Protezzjoni (OVP): Jekk l-output voltage exceeds the set OVP limit (default 38V), the device will activate protection. Check your load and settings.
• Protezzjoni ta' Kurrent Żejjed tal-Ħruġ (OCP): If the output current exceeds the set OCP limit (default 6.2A), the device will activate protection. Verify your load's current draw and adjust settings if necessary.
• Output Overpower Protection (OPP): If the output power exceeds the set OPP limit (default 125W), the device will activate protection. Reduce the load or ensure adequate cooling.
• Protezzjoni minn Temperatura Żejda (OTP): If the internal temperature reaches 100°C (or the set OTP limit), the device will shut down to prevent damage. Ensure the fan is unobstructed and the device has sufficient ventilation.
• Input Reverse Connection Protection: The device is protected against reverse connection at the input terminals. If connected incorrectly, it will not burn, but it will not operate. Correct the polarity.
• Protezzjoni ta' Short Circuit tal-Ħruġ: The output terminals are protected against short circuits. If a short circuit occurs, the device will not be damaged. Remove the short circuit.
• Output Anti-backflow: When charging a battery, the anti-backflow protection prevents current from flowing back into the power supply. If charging is not occurring, check battery connections.
