emonVS

AC voltage sensor and power supply for emonTx and emonPi

Inputs

Outputs

• The RJ45 connector is used to provide 5V DC power supply and AC voltage sample to emonTx and emonPi
• The 2-pins terminal block connector from emonVS (CN3) can supply 5V power to an emonBase using a open-ended USB-C connector.
