Installation & Operating Notes

Power Supply Sizing: Ensure your input power source can deliver the full power required by your load. The converter will fold back output voltage if input power is insufficient.

Example: If your 24V load draws 4A (96W) but your 48V input supply can only provide 1A (48W), the converter will reduce output to 12V (48W ÷ 4A = 12V).

Wiring:

• Input: Red wire = +V, Black wire = -V (30-60V DC)
• Output: Yellow wire = +V, Black wire = -V (24V DC)
• For wire runs exceeding 50cm (20"), use heavier gauge wire to compensate for voltage drop
• Ensure all connections are secure and properly insulated

Thermal Management: While this converter uses natural convection cooling, ensure adequate airflow around the unit. Avoid enclosing in sealed boxes without ventilation. Monitor case temperature - it should not exceed 83°C during operation.

Long Wire Runs: For applications requiring long cable runs, place the longer wiring on the INPUT side (higher voltage, lower current) to minimize voltage drop and power loss.
