3. Setup Instructions

Before connecting the module, ensure all power sources are disconnected. Proper wiring is crucial for safe and effective operation.

3.1 Wiring Connections:

1. Identify the input terminals: VIN+ (positive input) and VIN- (negative input).
2. Identify the output terminals: OUT+ (positive output) and OUT- (negative output).
3. Connect your DC power source to the VIN+ and VIN- terminals. Ensure the input voltage is within the specified range of DC 6.0-36V.
4. Connect your load (e.g., LED, motor, battery) to the OUT+ and OUT- terminals.
5. Ensure all connections are secure and that no bare wires are exposed to prevent short circuits. The screw-down terminals are designed to accept large-gauge wire for secure connections.

Note: The module includes output anti-backflow protection, allowing direct charging of rechargeable batteries without an additional anti-backflow diode. However, always verify polarity before connecting batteries.

4. Operating Instructions

The DROK Buck Boost Converter features an intuitive interface with a digital display and a rotary encoder for precise control.

4.1 Power On/Off:

• Press the yellow ON/OFF button to toggle the output power. The display will show "ON" or "OFF" accordingly.
• The display remains active even when the output is off, allowing you to pre-set voltage and current limits before applying power to your load.

4.2 Adjusting Voltage and Current:

• Rotate the silver knob (rotary encoder) to adjust values.
• Press the rotary encoder to select which digit or parameter you wish to adjust. Repeated presses cycle through available settings.
• The display shows the set voltage (SET: XX.XXV) and set current (X.XXXA) at the bottom.
• The module supports constant voltage (CV) and constant current (CC) modes. The "CC" indicator illuminates when the current drawn exceeds the set limit, and the power supply is regulating to the set current value.

4.3 Digital Display Modes:

The display provides comprehensive real-time data. You can cycle through different display screens by pressing the rotary encoder or the ON/OFF button (depending on the specific mode and firmware version).

Figure 4.1: Examples of various display screens, including real-time measurements and configuration menus.

• Main Screen: Displays real-time output voltage, current, and power.
• Capacity/Energy/Time Screen: Shows accumulated electric capacity (AH), energy (WH), and running time.
• Settings Screen: Allows configuration of parameters like over-voltage protection (S-OVP), over-current protection (S-OCP), and input low-voltage protection (S-LVP).
• Voltage/Current Curve: Visual representation of voltage and current over time.
• Theme Colors/Brightness: Adjust display appearance.

4.4 Memory Functions:

The module can store up to 10 data groups (M0-M9). M0 is the default storage location. M1 and M2 can be quickly recalled using specific button combinations (refer to the detailed manual for exact steps).

5. Maintenance

To ensure the longevity and optimal performance of your DROK Voltage Regulator, follow these maintenance guidelines:

• Cleaning: Keep the module clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using liquid cleaners or solvents.
• Ventilation: Ensure the cooling fan and ventilation slots are not obstructed. The fan activates automatically when needed to dissipate heat.
• Storage: When not in use for extended periods, store the module in a cool, dry place away from direct sunlight and extreme temperatures.
• Connections: Periodically check all wiring connections to ensure they remain tight and secure. Loose connections can lead to unstable operation or damage.
