あ及び五を介して行なわれるようになっている。The AC power supplied to the device 30 passes through the transformer 31 to D.
The D obtained here is converted to DC power by the C power supply device n.
C power is supplied to the electronic circuit within the device I, and is also supplied to the common motor mills U and 35. The common mode choke 351 has a winding configuration as shown in Figure 3, and the noise-insulated DC power supply is connected to the equipment and electronic circuits 41 and 51 in the garden through the common mode choke 351. supplied to Further, noise isolation of signals between the device I and the devices 40 and 50 is performed via photocouplers A and V.
