5.2.5. Power supply
The power supply is responsible for providing the necessary DC
power for the different functional parts of the device along with
the analog input channels, and the PT100 channel. The power
supply is protected against incoming network disturbances. The
power supply is protected against overvoltage and overcurrent,
protecting the inner parts of the device.
Input voltage
100 – 240 VAC (50Hz/60Hz)
Power consumption
< 15 VA AC
Terminal type
3 poles (L, N and PE)
Terminal isolation
AC 3 kV
Polarity
AC:
L: line, N: Neutral, PE: Protective
