400W DC Voltage and Current Adjustable Step-Down Power Module for Electronic Devices

Main Features of Power Module • Wide input voltage range: 10–60 V, compatible with most standard power supplies. • Constant voltage and constant current output; both voltage and current are continuously adjustable. Suitable for a wide range of electrical equipment. • High output power capability: up to 280 W or 12 A under proper ventilation and natural heat dissipation conditions. (Note: Output power and current are subject to operational limits.) • Uses a step-down rectification design for high efficiency—up to 92%–96% or higher—when output voltage exceeds 10 V. • Built-in constant-current indicator for clear battery charging status monitoring. • Input protection includes a 15 A fuse; reverse input polarity will blow the fuse but will not damage the module (fuse replacement required). Module Specifications • Module Name: 400 W Buck Constant Voltage & Constant Current Module • Module Type: Non-isolated buck (step-down) module • Input Voltage Range: 10.5–60 V • Output Voltage Range: 0–45 V (subject to step-down constraint: output ≤ input × 0.8) • Minimum Output Voltage: 0 V (typical start-up threshold ~1 V) • Maximum Output Voltage: Approximately 80% of input voltage (e.g., with 40 V input, max output ≈ 32 V) • Color: Blue • Material: PCB • Package Includes: 1 × Module • Note: Product appearance and color may vary slightly between batches without affecting functionality. • Note: Screen/display variations and lighting conditions may cause slight color differences between images and the actual product. Measurement tolerance: ±1–3 cm.
