Input voltage range: 15V-90V; output voltage range: 2.5V-72V, accommodating diverse power supply and equipment requirements Supports maximum power output of 1500W, suitable for high-power devices to ensure stable power delivery Features constant voltage output to guarantee output stability, ideal for applications demanding precise voltage control Adjustable output voltage provides flexible adaptation to varied application scenarios, enhancing usability Efficient buck conversion reduces energy loss, improves system efficiency, and minimises heat generation Product Specifications: Module Type: Non-isolated buck converter (BUCK) Input Voltage: DC 15-90V (Alternatively, 10-15V input is possible by shorting the '12-15V' terminals. Once shorted, only 10-15V input is permitted. Inputs exceeding 15V will damage the module; shorting '10-15V' renders the ON/OFF function inoperative) Output Voltage: 2.5-72V (must satisfy step-down condition: IN input multiplied by 0.8 equals maximum output voltage) Minimum Output Voltage: 2.5V Maximum Output Voltage: 72V (at 90V input; IN voltage x 0.8 equals output voltage) Maximum Output Current: 1500W model 50A Cooling method: Air-cooled Input reverse polarity protection: None (reverse connection strictly prohibited) Input under-voltage protection: None Input over-voltage protection: None (overvoltage prohibited) Output ON/OFF switch interface: Present (requires user wiring) Operating temperature: -10 to +65°C Operating frequency: 80kHz Conversion efficiency: Up to 97% (efficiency depends on input/output voltage, current, and voltage differential) Short-circuit protection: None (current limiting up to 30A/50A possible) Cooling method: Air-cooled (thermostatically controlled fan activates around 45°C) Color: Black Material:Metal+Plastic Package Contents: 1*Power module Only the above package content, other products are not included.
