Module parameters:

DC-DC non-isolated high voltage step-down power module

Wide voltage input: 12V-120V (120V is the limit voltage, leave room for long-term work);

For the first use, it is recommended to connect a power supply of more than 30V;

Adjustable output voltage: adjustable between 1.5V-48V;

Input and output voltage difference: 5V (ie output voltage < input voltage -5V);

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;

Built-in over temperature, over current, output short circuit protection

Built-in soft start

：Switching frequency: 110KHZ

：Operating temperature: Industrial grade (-40°C to +85°C)

：The size of the board: 4.4*2*1.4cm

：Input mode: IN+ input positive level, IN- input negative

：Output mode: OUT+ output positive, OUT- output negative

Instructions:

：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).

：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.

：The electrical equipment (load) is connected to the output end of the module.

：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.
