- Input Reverse Connection Protection: Protects the module from damage due to incorrect input polarity.
- Pelindung Casing: Includes a transparent acrylic case to prevent physical damage to the module.
3. Tindakan pencegahan keselamatan
- Pastikan input voltage polarity. The module has input reverse connection protection, but always verify connections.
- Ada no reverse current protection on the output terminals. Do not connect a battery or other power source to the output without an external diode to prevent reverse current flow, as this can damage the module.
- Do not short-circuit the Input IN- terminal to the Output OUT- terminal. This will disable the constant current function.
- Ensure proper ventilation, especially when operating at higher currents (above 3.5A) to allow for adequate heat dissipation.
- Always verify the output voltage setting before connecting any load to prevent damage to your devices.
- Handle the module with care, especially during assembly of the acrylic case, to avoid damage to components.

5.2 Acrylic Case Assembly
The module comes with a transparent acrylic case for protection. Assembly is straightforward:
- Identify the top and bottom acrylic plates, standoffs, and screws.
- Carefully align the bottom acrylic plate with the mounting holes on the PCB.
- Insert the brass standoffs through the bottom plate and into the PCB.
- Place the top acrylic plate over the standoffs, ensuring all cutouts align with the module's components (terminals, buttons, screen).
- Secure the top plate with the remaining screws. Do not overtighten.

5.3 Koneksi Kabel
Connect your power source and load to the module using the screw terminals:
- Input (IN+ / IN-): Connect your DC power source (6.5V-36V) to these terminals. Ensure correct polarity: IN+ for positive, IN- for negative.
- Output (OUT+ / OUT-): Connect your load to these terminals. Ensure correct polarity: OUT+ for positive, OUT- for negative.
Note: Always double-check wiring before applying power.
6. Petunjuk Pengoperasian
6.1 Daya Hidup/Mati
- After connecting the input power, the LCD will light up.
- Tekan tombol AKTIF/NONAKTIF button (usually on the left side) to toggle the output power.
- To set the default power-on state (output ON or OFF), press and hold the AKTIF/NONAKTIF button. The module will remember this setting for subsequent power cycles.
6.2 Adjusting Output Voltage
volume keluarantage is adjusted using the two buttons on the right side of the module:
- Tekan tombol '+' button to increase the output voltage.
- Tekan tombol '-' button to decrease the output voltage.
- The LCD will display the current output voltage during adjustment.
6.3 LCD Display Modes
The module features an LCD that can display various parameters. Use the button on the left (often labeled 'IN/OUT' or similar) to cycle through display modes:
- Volume Keluarantage (OUT V): Menampilkan volume keluaran saat initage.
- Masukan Voltage (IN V): Menampilkan volume input saat initage.
- Volume Masukan/Keluarantage (IN/OUT V): Alternates between input and output voltagtampilan.
- Output Current (OUT A): Displays the current flowing through the output.
- Output Power (OUT W): Menampilkan daya keluaran yang dihitung.

6.4 Constant Current (CC) Adjustment
The module supports constant current output. The current limit can be adjusted using the small potentiometer (ADJ-I) on the board. Turn clockwise to increase the current limit. This is typically set to approximately 4.2A-4.5A at the factory.
7. Pemeliharaan
- Jaga agar modul tetap bersih dan bebas dari debu dan kotoran. Gunakan kain lembut dan kering untuk membersihkan.
- Ensure adequate airflow around the module, especially when operating at higher loads, to prevent overheating.
- Regularly check wiring connections for tightness and signs of wear or corrosion.
- Hindari memaparkan modul pada kelembapan, suhu ekstrem, atau lingkungan korosif.
8. Penyelesaian masalah
| Masalah | Kemungkinan Penyebab | Larutan |
|---|---|---|
| Tidak ada tampilan/Tidak ada output | No input power; Incorrect input polarity; Output turned off. | Check input power connections; Verify input polarity; Press the ON/OFF button to enable output. |
| Volume keluarantagini tidak dapat disesuaikan | Potentiometer at its limit; Faulty potentiometer. | Ensure the adjustment buttons are being pressed correctly; If still unresponsive, contact support. |
| Constant current function not working | Input IN- short-circuited to Output OUT-. | Check wiring to ensure IN- and OUT- are not connected. |
| Modul terlalu panas | Excessive load current; Insufficient ventilation. | Reduce load current; Ensure adequate airflow around the module; Consider adding a fan for continuous high-current operation. |
