Tax included.


DC-DC non-isolated step-down power supply module High voltage input buck board

Input voltage: 9V-90V
The minimum voltage difference between the input voltage and the output voltage is 4V (the input voltage is DC9-90V when the output is 5V, and the input voltage is DC16-90V when the output is 12V)
Output voltage:12V/5V
The output current is up to 3A (ie constant current value 3A, when the custom voltage is greater than 12V, the output current is less than 3A, the maximum power is recommended not to exceed 30W)
Typical operating frequency: 140KHz
High efficiency: up to 95% (the smaller the differential pressure, the higher the efficiency)
Light load frequency reduction to improve light load efficiency
Small standby current
Built-in over temperature, over current, output short circuit protection
Built-in soft start
Constant voltage constant current output
Operating temperature: industrial grade (-40 ° C to +85 ° C)
Module volume: 42*30*17mm

1. Connect the cable between the module and the power supply first, and then power on. Remember! Remember! (If the input terminal is energized, it is prone to sparking, especially when the input power supply voltage is high, even burning the module's pad).

2. After selecting the appropriate power supply, use a multimeter or voltmeter to measure whether the output voltage of the module matches the voltage required by the device.

3. Connect the electrical device or (load) to the output of the module.
