ITEM NAME:DC-DC 200W 15A Adjustable Drop Isolation Pressure Reducing Module Durable QEM Descriptio n Description: Rectification mode: synchronous rectification Type: Non-Isolated Decompression Module (BUCK) Input Voltage: 8-55V (Limit 60V, please leave a margin) Output Voltage: When 1-35V continuously adjustable voltage, please be careful not to exceed this range. The input voltage of step-down power supply should always be greater than the output voltage and at least 1V voltage difference. Input power = output power + loss (energy conservation principle) Output Current: The current marked in 15A (MAX) for a long period of 10A is the maximum current (measured 12 to 5 V). The actual output current is not fixed, which is related to input-output voltage difference, temperature and other.We'd like to settle any problem in a friendly manner. Type: Non-Isolated Decompression Module (BUCK). Reverse protection Working temperature: -10~+85 degrees. We want to make sure you are happy with our item.
