This kit is not assembled, user has to assembly.
This board can check that in AC lines has the current flow just put the board close to AC lines ( approximately 1cm ), If in AC lines has the voltage flow, LED will blinking.
Technical information:
- Check AC lines which have voltage 110VAC to 240VAC
- Require power supply 9VD or 9VDC battery
- Current consumed 4mA ( when LED is blinking ) and 1.2mA when in stand by mode
- Indicator by RED LED
- Distance to detect voltage in AC lines approximately 1cm
- Adjustable the sensitivity to detection
- PCB size 2.3" x 1.29"
