1、A new technology that uses synchronous rectification technology and uses low on‑resistance power to replace rectifier diodes to reduce rectification losses. 2、Synchronous rectification technology is to reduce the rectification loss at the output of the switching power supply, thereby improving the conversion efficiency and reducing the heating of the power supply itself. 3、With short circuit protection and reverse connection protection, and with shell protection. 4、Small size, easy to carry and store, convenient to use and with good performance. 5、The power module made of high-quality materials, strong and durable, has a long service life. 1 x Power Module Item Type: Power ModuleProduct Material: ABSProduct Model: 48V to 15ARectification Method: Synchronous rectificationType: Non-isolated reduced voltage module (BUCK)Input Voltage: 8-55V (limited to 60V, please leave margin)Output Voltage: 1-35V continuously adjustable. Please be careful not to exceed this range when adjusting the voltage. The input voltage of the reduced voltage power supply should always be greater than the output voltage and at least 1V differential pressure, input power = output power + loss (the principle of energy conservation)Output Current: 15A (Maximum) for a long time within 10A, the marked current is the maximum current under specific conditions (measured 12 down 5V) The actual output current is not fixed, it is related to the input and output pressure difference, temperature and other conditionsOutput Power: Well ventilated, natural heat dissipation power, long-term 100W, enhanced heat dissipation up to 200W, if you work for a long time, please leave a margin to pay attention to temperature rise and make good heat dissipation.Working Temperature: -10~+85 degreesWorking Frequency: 180KHzConversion Efficiency: 94% typical (efficiency is related to input, output voltage difference, and output current)Short Circuit Protection: Yes (short circuit output current is 0)Reverse Connection Protection: YesWiring Mode: High Current Terminal, No Welding, IN+: Input Positive, IN-: Input Negative, OUT+: Output Positive, OUT-: Output negative
