Step-by-Step Installation Guide

Follow these simple steps to integrate the converter into your system quickly and securely.

1. Prepare Wires: Strip 10 mm of insulation from each input/output wire.
2. Connect Input:
   • Red (R+) → 48V DC positive
   • Black (B–) → 48V DC negative
3. Connect Output:
   • Yellow (Y+) → 12V device positive
   • Black (B–) → 12V device negative
4. Lock Terminals: Press down lever nuts firmly until wires are secure.
5. Verify Output: Power up and check 12V ±0.24V with a multimeter.

Pro Tips for Best Performance

Ensure peak efficiency and longevity by following these practical recommendations.

• Choose the Right Wire Gauge: Use 14 AWG or thicker for 5A continuous loads to reduce voltage drop.
• Mind Power Limits: Keep continuous load under 60W; allow brief peaks if needed.
• Mount Correctly: Install upright with terminals facing down to avoid water pooling.

Frequently Asked Questions (FAQ)

Quick answers to common concerns and operational questions.

Q1: Can I run a 12V LED strip from a 48V input?
Yes—this converter handles 48V→12V at 5A (60W), perfect for high-power LED installations.

Q2: Is it safe in saltwater or marine environments?
With its IP67 enclosure, it withstands splashes and temporary immersion. Rinse with fresh water after exposure to saltwater.

Q3: What happens if input voltage falls below 35V?
The unit automatically shuts off to protect the output when input drops below its minimum threshold.

Q4: Will it work with lithium battery systems?
Yes, compatible with 48V LiFePO₄, Li-ion, or lead-acid batteries as long as the input remains between 35–60V.
