5. Configuració i connexions
Refer to the images below for a visual guide to the device's interfaces.
Figure 1: Front panel of the converter (example display: 65.00V, 6.000A)
Figure 2: Front panel of the converter (example display: 65.00V, 9.000A)
Figure 3: Rear panel with input interfaces and exhaust fan.
The rear panel features multiple input options: a PD interface (for PD charging heads, automatically activating 20V output), a power battery interface, a DC 5.5*2.5 plug input, and a plug-in terminal. An exhaust fan for intelligent temperature control is also visible. Input voltage range is DC 6.0-70V. Crucially, do not connect two or more input interfaces simultaneously.
5.1. Connexió d'entrada
Choose ONE suitable input interface from the rear panel:
- PD Interface: Connect a PD charging head. The device will automatically activate to output 20V high voltage.
- Power Battery Interface: Connect a compatible power battery.
- DC 5.5*2.5 Plug: Use a standard DC 5.5*2.5mm power adapter.
- Plug-in Terminal: For custom wiring, ensure correct polarity (positive and negative).
Important: Only use one input source at a time. Connecting multiple sources simultaneously can cause severe damage to the converter.
5.2. Connexió de sortida
The output terminals are located on the front panel (typically red for positive, black for negative). Connect your load to these terminals, ensuring correct polarity.
6. Funcionament
The front panel features a digital display, control buttons (VSET, SW, ISET), a rotary encoder, and an ON/OFF button.
6.1. Encendre/apagar
After connecting the input and output, press the ON/OFF button to enable or disable the output power.
6.2. Configuració de la sortida Voltage (VSET)
- Premeu el botó VSET botó. El volumtage value on the display will start blinking.
- Rotate the encoder to adjust the desired output voltage.
- Press the encoder button briefly to switch between digits for fine adjustment.
- Premeu VSET again to confirm the setting and exit voltage mode d'ajust.
6.3. Setting Output Current Limit (ISET)
This device operates in constant voltage mode, but you can set a current limit to protect your load.
- Premeu el botó ISET button. The current value on the display will start blinking.
- Rotate the encoder to adjust the desired maximum output current.
- Press the encoder button briefly to switch between digits for fine adjustment.
- Premeu ISET again to confirm the setting and exit current adjustment mode.
6.4. Display Switching (SW)
El SW button allows you to cycle through different display modes, such as input voltage, voltage, output current, and power.
7. Manteniment
- Neteja: Feu servir un drap suau i sec per netejar el dispositiu. No utilitzeu productes de neteja abrasius ni dissolvents.
- Ventilació: Ensure the exhaust fan and ventilation openings are free from dust and obstructions. Periodically clean the fan if necessary.
- Emmagatzematge: Guardeu el dispositiu en un lloc fresc i sec quan no l'utilitzeu.
- Inspecció: Regularly check all connections for tightness and signs of wear or damage.
8. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Sense pantalla/Sense alimentació | No input power; incorrect input connection; input voltage massa baix/alt. | Check input power source; ensure correct polarity; verify input voltage està entre 6.0V i 70V. |
| Sense sortida voltage/actual | Output is OFF; output short circuit; overcurrent protection activated. | Press ON/OFF button to enable output; check load for short circuits; reduce load or increase current limit. |
| Volum de sortidatagcorrent elèctric inestable | Poor connections; faulty load; device overheating. | Check all wiring connections; test with a different load; ensure adequate ventilation. |
| Fan constantly running/loud | High load/temperature; fan obstruction. | This is normal under heavy load; ensure ventilation is clear. |
9. Consells d'usuari
- When using the PD interface, ensure your PD charging head can supply sufficient power for your desired output.
- Always double-check your voltage and current settings before connecting sensitive electronics.
- For long-term use at higher power, ensure the device is placed in a well-ventilated area to allow the intelligent fan to operate effectively.
