HW-140 DC-DC Buck Boost Converter Step Up/Down
The HW-140 power supply module is a multi-functional product that displays the input and output voltage, current or power in real time, switching via the IN/OUT buttons.The ON/OFF button is used to turn off the display or the output and to indicate the output status via LEDs. Voltage and current are adjusted by independent trimmers accurate to 0.01V and 0.001A respectively, and the CC lamp will light up when the current reaches the set value. The modules have a soft start and a built-in anti-reflow diode for a wide range of applications, especially to prevent reverse current flow and provide reverse connection protection during charging.
