DC-DC High-voltage Adjustable Step-down Board 48V 60V 100V Drop 1.25V-48V Voltage Rregulator Module Buck Converter Transformer
1: Wide range of applications
4: Built-in over temperature, over current, output short circuit protection
1. DC-DC non-isolated high voltage step-down power supply module
2. Wide voltage input: 12V-120V (120V is the limit voltage, leave room for long-term work); it is recommended to connect a power supply above 30V for the first use;
3. Adjustable output voltage: adjustable between 1.5V-48V;
4. Input and output voltage difference: 5V (ie output voltage < input voltage -5V);
5. Output current: 1.5A (Max) The value of each input voltage point is different from that of the output voltage point, see the parameter table below for details:
6. Built-in over temperature, over current, output short circuit protection
8. Switching frequency: 110KHZ
9. Working temperature: industrial grade (-40¡É to +85¡É)
10. Size of the board: 4.4*2*1.4cm
11. Input mode: IN+ input positive level, IN- input negative
12. Output mode: OUT+ output positive, OUT- output negative
1. First connect the connection line between the module and the power supply, and then turn on the power. Remember! Remember! (If the input terminal is live and wired, it is easy to spark, especially when the input power supply voltage is high, it will even burn the pads of the module).
2. For the first use, it is necessary to connect to a power supply of more than 30V; use a multimeter or a voltmeter to measure whether the output voltage of the module is consistent with the voltage required by the device.
3. The electrical equipment (load) is connected to the output end of the module.
4. When the difference between the input voltage and the output voltage is less than 5V, the output will be unstable or no output will occur.
