- Support: Backed by a 1-year warranty and lifetime technical support
Installation Instructions
Step-by-step setup:
- Confirm power input within specified voltage range
- Strip 10mm insulation from 18–12 AWG wiring
- Use lever terminals to connect wires:
- Input: Red (+)
- Output: Yellow (5V), Black (GND)
- Tighten waterproof gland nuts included with the unit
Tip: For marine or solar setups, applying dielectric grease (not included) can improve long-term connection integrity.
FAQs
Q: Can this replace a 220V wall adapter?
A: No. This unit requires a pre-regulated DC/AC source (e.g., car battery, solar system). For 220V input, use an additional AC-to-DC converter.
Q: How to check if my devices are within power range?
A: Add up the power draw: 5V × total current ≤ 15W. Example: a 5V/2A camera and 5V/1A sensor total 15W.
Q: What’s the EMI performance like?
A: Less than 30dBμV at 3 meters, fully compliant with EN55032 Class B, suitable for noise-sensitive applications.
