400W High-Power Step-Down Voltage and Current Adjustable Module for Constant Output

Main Features of Power Module: - 10.5–60V wide input voltage range, 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; with proper ventilation and natural heat dissipation, supports up to 280W / 12A (subject to output power and current limits). - Uses a non-isolated buck (step-down) rectification design for high efficiency. - Efficiency up to 92–96% at output voltages above 10V. - Built-in constant current indicator for battery charging—charging status is clearly visible. - Input protection includes a 15A fuse. Reverse input polarity will blow the fuse but will not damage the module (fuse replacement required). Module Parameters: - Module Name: 400W Buck Constant Voltage & Constant Current Module - Module Type: Non-isolated Buck (Step-down) Module - Input Voltage Range: 10.5–60V - Output Voltage Range: 0–45V (must satisfy step-down condition: output ≤ input × 0.8) - Minimum Output Voltage: 0V (±1V) - Maximum Output Voltage: Approximately input × 0.8 (e.g., with 40V input, max output ≈ 32V) Note: Appearance and color may vary slightly between batches—this does not affect performance. Color: Blue Material: PCB Package Includes: - 1 × Module Other items shown in images are not included. Note: Color appearance may vary slightly due to lighting and screen settings.
