Function


  • Operating mode description


  • With key off function, and reduce power consumption.


  • Power state can be freely defined


  • Input and output voltages can be displayed alternately


  • On/0ff output status, high level means output off, low level means output on. (note: high level (3.3v), the maximum output current 5mA)


  • Output voltage mode:Boot default display it, LED indicator off


  • Input voltage mode:Press button switch to it , LED indicator on


  • Alternating mode:Press button again input/output voltage alternately display (3s). Press button again, switch to output voltage display

Features:


  • In+:                                    Input positive


  • In-:                                    Input negative


  • Out+:                                  Output positive


  • Out-:                                  Output negative


  • weight:                                 20g


  • Dimensions:                             62 *26 *14mm(length*width*height)


  • Ripple peak:                             About 100mV


  • Display color:                            Red/Green/Blue


  • Input voltage:                            4.5-28V


  • Output power:                            15W maximum


  • Output voltage:                           1.3v-25v (step-down mode, the input voltage must be 2v higher than the output voltage)


  • Output current:                            1.5A


  • Ripple frequency:                         About 150KHZ


  • Voltage meter accuracy:          ±(5 ‰ +1 digit)


  • Static power consumption:    Typical about 20mA


 

Stop working mode

 

Keep pressing the button until the monitor does not display numbers ( long press more than 4s) and release the button. LED lights and module shuts down. The output voltage is zero. At this time, it does not perform memory function. ON / OFF output high level (3.3V), then the static power consumption is about 2mA. Click the button, the module starts working again.
