Features:
- DC-DC 48V step-down to 12V 40A 480W voltage transformer
- High reliability and conversion efficiency, wide input voltage range
- Die-cast aluminum shell, sealed with thermal conductive silicone for achieving natural heat dissipation, waterproof, dustproof and shockproof
- Built-in over-temperature , over-current, over-voltage, output short- circuit protection
- Auto-recovery when device is back to normal operating
- Compact in structure, easy to install

Kindly Note:
1. Input voltage must be higher than the output voltage, no boost
2. Do not reverse the input and output interface
3. Give preference to stable DC power as the input power supply, or filter it with capacitor If you use the pulsed DC power provided by the generator
