Synchronous rectification technology delivers high efficiency and savings, significantly reducing power loss Constant voltage adjustable design enables precise output voltage regulation to accommodate multiple device requirements Integrated module structure facilitates straightforward installation, saves space, and enhances system stability Product Specifications: Module Type: Non-isolated buck converter (BUCK) Input Voltage: DC 15-90V Output Voltage: 2.5-72V Maximum Output Power: 1200W Continuous Rated Power: 1000W/1200W Maximum Output Current: 30A/50A Rated Output Current: 28A/45A Typical Efficiency: 95% (90%-97%) Operating Frequency: 70kHz Input reverse polarity protection: None (reverse connection strictly prohibited) Output constant voltage indicator: Yes Cooling method: Thermally controlled fan cooling Operating temperature: 0-85°C Application scenario: Converts high voltage to low voltage for regulated power supply to equipment Important notes: 1. This power supply is a step-down converter; it can only reduce voltage, not increase it. 2. Input polarity must not be reversed. 3. This is a constant-voltage power supply with non-adjustable output current. Not recommended for constant-current battery charging or LED constant-current driving. 4. When connecting to a motor, series-connect a Schottky diode rated for 50A or higher at 100V across the positive output terminal to prevent back-current. Avoid prolonged operation at maximum power/current; maintain at least 20% reserve capacity during extended use.
