3. Setup
Follow these instructions for proper wiring and installation of the converter.
Wiring Instructions:
- Input Side:
- Red Wire: Connect to the positive (+) terminal of your DC 5-11V input power source.
- Black Wire: Connect to the negative (-) terminal of your DC 5-11V input power source.
- Output Side:
- Yellow Wire: Connect to the positive (+) terminal of your 12V load device.
- Black Wire: Connect to the negative (-) terminal of your 12V load device.
Ensure all connections are secure and correctly polarized to prevent damage to the converter or connected devices.

4. Operating Instructions
Once properly wired, the DROK 5V to 12V Step Up Converter operates automatically to provide a stable 12V output.
- Connect Input Power: Apply a DC voltage between 5V and 11V to the input (red and black wires).
- Connect Load: Connect your 12V device to the output (yellow and black wires).
- Verify Output: The converter will automatically regulate the output to 12V. You can use a multimeter to verify the output voltage if necessary.
- Overload Protection: If the connected load exceeds 3A (36W), the device is designed to shut off the output to protect itself. Remove the input voltage briefly and reduce the load before reapplying power to restore normal operation.

5. Maintenance
The DROK 5V to 12V Step Up Converter is designed for durability and requires minimal maintenance.
- Environmental Protection: The converter's waterproof, dustproof, moisture-proof, and shockproof aluminum casing allows it to function reliably in various harsh environments.
- Cleaning: If necessary, gently wipe the exterior with a dry, soft cloth. Do not use harsh chemicals or immerse the unit in liquids.
- Inspection: Periodically check the wiring connections for any signs of wear, corrosion, or looseness. Ensure all connections remain secure.
- Ventilation: While the aluminum shell aids in cooling, ensure the unit is not completely enclosed in a way that prevents any heat dissipation, especially when operating under heavy loads.
