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)
Package contents:
1200W/1500W buck module ×1 (optional)
