4. Adjustable output voltage provides flexible adaptation to varied application scenarios, enhancing usability

5. 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 × 0.8 equals output voltage)

Maximum Output Power: 1200W/1500W (selectable) (requires well-ventilated operating environment)

Continuous Rated Power: 1200W model 1000W / 1500W model 1200W (in ventilated environment)

Continuous Rated Current: 1200W model 25A / 1500W model 45A (in ventilated environment)

Maximum Output Current: 1200W model 30A / 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)

Output reverse current protection: None (output connected to inductive loads, e.g., motors, must incorporate reverse protection diodes)
