  • Liquid system tool having an integrated residual current device
    Patent number: 10666041
    Abstract: Disclosed herein is a liquid system tool having an integrated residual current device, RCD. The liquid system tool comprises a current circuit having a power input for receiving an alternating electrical current, AC, a rectifier for rectifying the AC into a direct current, DC, a voltage booster for increasing a DC voltage and a motor unit connected to an output of the voltage booster for driving the liquid system tool. The RCD comprises a sensor element connected to an output of the rectifier and an input of the voltage booster and being configured to collect an analog current signal and an analog to digital, A/D, converter configured to convert the analog current signal into a digital current signal.
    Type: Grant
