Product features
Choose double-sided thickened high-quality PCB board, all use imported alumin um chip electrolytic capacitor, high Q value high-power inductor. In addition, each board has passed strict technical testing, specially designed 2 screw fixing holes. The four input and output pads are provided with a row of pin fixing holes.
Product parameters
Input mode: IN+ input positive stage, IN- input negative pole
Output mode: OUT+ output positive stage, OUT- output negative pole
Input voltage: 4.5-50V
Adjustment mode: first correctly connect the input power supply (between 4.5-50V), then use a multimeter to monitor the output voltage and adjust the potentiometer (generally turn to boost in accordance with the timing, turn to buck in reverse).
Output voltage: (3-35V) continuously adjustable (no-load debugging is recommended) the default delivery voltage of the store is 5V. If other voltage is required, it can be adjusted by itself.
Limited differential pressure: 1.5V
Output current: rated current 2A, 12V to 5V maximum 3A
Output power: maximum 15W
Conversion efficiency: 92% (the higher the output voltage, the higher the efficiency)
Static power consumption: only about 6mA
Connection mode: welding, can be directly welded on PCB after adding pin
Operating temperature: Industrial grade (-40℃~+85℃)
Load adjustment rate: ±1%
Voltage adjustment rate: ±0.5% (in order to reach the no-load output voltage will be higher, but as long as there is 1mA load, the output voltage will be normal, does not affect the function, please rest assured to use)
Short circuit protection: current limiting, overheating protection, self-recovery.
Special attention: the low voltage difference limit: 1.5V, because it is a step-down module, in order to ensure stable output, please keep the low voltage difference limit of 1.5V.
Using range
-
Vehicle voltage regulator power supply, just need to connect the input end of the module to the car cigarette holder power supply, you can adjust the potentiometer, the output voltage can be adjusted in 4.5-50V by you (because it is the buck module, so the output voltage is more than 1.5 lower than the input);
-
Power your mobile phone, MP3, MP4, PSP charging and many other devices;
-
Power supply for your electronic equipment, when your equipment needs 3-35V power supply, but now you only have 12V or 24V 36,48V battery power supply, with our module can directly buck to 3-40V to solve your problems;
-
Pre-system power supply, when you are working on a project when the input power supply voltage is lower than the voltage you need (3-40V).
