6.8.2 Design of a separate power supply for the SCK-M-U-1500V
voltage measuring module
The voltage measuring module can also be used as a simple analog measuring transducer
outside of the Solarcheck device range. In this case, power is not supplied via the connec-
tion to the SCK-M-I-8S-20A Solarcheck current measuring module, it must be supplied sep-
arately instead. A 24 V DC power supply must be provided. The typical current consumption
is 8 mA. The maximum current consumption is 65 mA. The maximum current consumption
only occurs if the value falls significantly below the minimum input voltage.
