Hi all, I need to detect the current used by a washing machine powered with a 230 V, and after trying a type of sensor with no results I would use one of these current transducers: http://docs-europe.electrocomponents.com/webdocs/008f/0900766b8008f208.pdf In detail, an AS-100 or AS-104 but looking datasheet or on the net I only found this site: http://dcc-mueller.de/wire4dcc/sensor_e.htm But I do not know if the circuit in Figure 4 can be used directly or whether it should be placed downstream of the circuit in Figure 1 or 2. Attempting to calculate the shunt resistor for the sensor AS-104 according to the datasheet: VMS = Rt x Is x (1/2F) Rt (Ohms) = Recommended terminating reisstance Is (A) = Secondary Current F (Hz) = Frequency in the table shows a value of 1500 for the VMS component AS-104, and a value of Is 30mA then the calculations that I made I put a 200 ohm resistor but I'm not sure I understood correctly the Datasheet: 1500 = Rt x 0.3 x (1/2 * 50) Rt = 1500 / 0.3 x 25 = 1500 / 7.5 = 200

I thank in advance those who will help me Hello
