7.2 Replacement of the KROHNE FlexPower unit
The WATERFLUX 3070 can be used with an (optional) external, main supply power pack which is
suitable for pulse output or isolated Modbus.
The KROHNE FlexPower provides the necessary power supply for the IFC 070 signal converter.
An extern supplied voltage to the KROHNE FlexPower results in a 4.2 V DC output.
When a main power failure occurs, the internal dual D-cell battery will take over the power
supply to the IFC 070 signal converter as back up, with a voltage of 3.6 V DC
More information about battery lifetime can be found in refer to

The input power for the KROHNE FlexPower can be realized by connecting :
•
an AC mains supply source; range 110...230 VAC - 50/60 Hz
or
•
a DC supply source; range 10...30 VDC
