Main Features of Power Module: - 10.5–60V wide input voltage range, compatible with most standard power supplies. - Constant voltage and constant current output, with continuously adjustable voltage and current settings. - Suitable for a wide range of electrical equipment. - High output power: up to 280W at 12A (subject to output power and current limits). - Efficient step-down rectification design; 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 (fuse replacement required). Module Parameters: - Module Name: 400W Buck Constant Voltage & Constant Current Module - Module Type: Non-isolated buck converter - 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: ~80% of input voltage (e.g., with 40V input, max output ≈ 32V) Note: Appearance and color may vary slightly between batches—this does not affect functionality. Color: Blue Material: PCB Package Includes: 1 × Module This listing includes only the module. No additional accessories or components are included. Note: Color representation may vary slightly due to screen settings and lighting conditions. Measurement tolerance: ±1.3 cm.
