Features Replace the rectifier diode with a dedicated power MOSFET with very low on-state resistance to reduce rectification losses. Synchronous rectification technology is adopted to improve conversion efficiency and reduce heat generation of the power supply itself. Adopted of high quality electronic components, and accuracy process, ensure for the durability. High conversion efficiency, with input anti-reverse connection function. Suitable for applications where the input voltage is higher than the output voltage. Specification:Item Type: Step Down ModuleInput Voltage: 10-90VDC Output Voltage: 2-60VDC Adjustable (for applications where the input voltage is higher than the output voltage) Output Current: Maximum 6A (use derating when high voltage output, external heat dissipation is required for module temperature over 65 degrees) Maximum Power: 100W (maximum current 6A at low voltage output) Working Frequency : 180KHZ Conversion Efficiency : 97.5% (typical) Input Anti-Reverse Connection: Yes Aluminum Case Size: Approx. 70 x 38 x 31mm / 2.8 x 1.5 x 1.2in Package List:1 x Step Down Module Package List 1 x Step Down Module
