Parameter Wide voltage input: 12V-120V (120V is the limit voltage, leaving room for long-term operation). It is recommended to connect the power supply above 30V for the first time; Adjustable output voltage: 1.5V-48V adjustable; Input output voltage difference: 5V (i.e. 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 following parameter table for details; Plate size: 44*21mm The following table shows the of several common voltage points, which are for reference only. The actual use conditions of each customer cannot be completely consistent, so the will be different - please refer to the data measured in the real environment.

Built in over-temperature, over-current and output short-circuit protection Built in soft start Switching frequency: 110KHZ Working temperature: industrial grade (- 40℃ to + 85℃) Input mode: IN+ input positive stage, IN- input negative pole Output mode: OUT+ output positive stage, OUT- output negativeUsage Method 1. Connect the connecting wire between the module and the power supply before power on. Remember! Remember! (if the input terminal is electrically connected, it is easy to cause ignition, especially when the input power supply voltage is high, even the pad of the module will be burnt). 2. The first use requires access to a power supply of more than 30V; Use a multimeter or voltmeter to measure whether the output voltage of the module is consistent with the voltage required by the equipment. 3. The electric 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.
