Package Include:
1x DC Converter

  • The input and output voltage can be displayed alternately; boot-up state can be freely defined; with button Off function, lower power consumption.
  • ON/0FF output working status, high electric level means output off, low level means output on. (Note: High level (3.3V), the maximum output current 5mA.)
  • There are three working mode for this product: output voltage mode, Input voltage mode and alternating mode.
  • Boot up refers to output voltage mode by default, LED indicator off; press buttom one time to switch to input voltage mode, LED indicator on; press button again, input and output voltage alternately display for 3s, then press button again, switch to output voltage display mode.
  • There are also the other two modes, which are memory mode and stop working mode.
