400W High-Power DC-DC Buck Converter 10V-60V Adjustable CV/CC Power Supply Module

Product Features

• Wide input voltage range of 10-60V, compatible with most power supplies on the market.
• Output supports both constant voltage and current, with continuously adjustable settings to meet the needs of most electrical equipment.
• High power output with excellent ventilation and natural heat dissipation, achieving up to 280W/12A.
• Efficient step rectification scheme, achieving over 92%-96% efficiency for output voltage above 10V.
• Constant current indication when charging batteries for clear status visibility.
• Equipped with a 15A fuse to protect against accidental reverse connection of input voltage (fuse replacement required upon burnout).
