XH-M133 DC-DC Adjustable Step Down Power Supply Module Buck Converter Voltage Regulator 4-38V to 1.25-36V
Product Details
Description:
This is a constant voltage constant current power output module. The conversion efficiency is as high as 96%. The maximum is 5A or 150W output.
The module has a precision adjustable output voltage potentiometer with green indicator light status. The whole is patch design.
It is with high efficiency and fast, which is the preferred product of voltage regulation / charging.

Features:
1>. Increase radiator heat dissipation effect, stable performance.
2>. With working light, clear and intuitive working state
3>. Large area copper cladding can improve heat dissipation and maintain stable performance.
Using Attention:
1>. All wiring must be done when the power is disconnected.
2>. The input is lower than 5V can also reduce blood pressure. But the light doesn't turn on. More than 5V can be normal light
3>. The defaults to 5V. if the adjustment voltage and output current to turn several rounds, the potentiometer adopts reflection mode.
4>. In actual use, severe fever may occur depending on the load. When the load is more than 3A, heating 100 degrees is the normal temperature.
5>. If the load is longer than 3.5A, it is recommended to use a fan to blow the module to reduce the temperature and prolong the service life.
6>. During the charging process, a number of colleagues will appear, indicating the real mode handover. This is a normal phenomenon.
7>. The input must use an adapter or a switching power supply. If you use the transformer, must be rectified and filtered to use.
8>. Pay attention to board damp proof and insulation to avoid unnecessary losses caused by short circuit.
