10.3. Feeding devices
RSE can ONLY be fed by a separate approved battery pack.
Metrological battery
The feeding of the metrological equipment is guaranteed by a non-rechargeable lithium battery with a duration > 15 years under
reference operating conditions (see table below).
A single, non-rechargeable, cell with Lithium
–
Thionyl chloride technology (Li-SOCl
2
) is used
The main features are:
Size C with Bobbin technology;
Rated voltage equal to 3.6 Vdc.
Rated capacity of about 8.5 Ah.
The Bobbin technology assures a maximum current limited by significant intrinsic internal resistance; however, it still provides sufficient
current for the device operation.
Wiring with polarized connector, to assure proper connection to the printed circuit board.
The cell is fastened inside the meter; it cannot be replaced and it is protected by metrological seals.
169 MHz radio battery
The radio version has an additional non-replaceable battery, placed in the metrological area and, therefore, not accessible by the
operator.
A single, non-rechargeable, cell with Lithium
–
Thionyl chloride technology (Li-SOCl
2
) is used
The main features are:
Size C with spiral technology;
Rated voltage equal to 3.6 Vdc.
Rated capacity of about 7.0 Ah.
The spiral technology allows the battery to provide peak currents appropriate for the operation of the enhanced 169 MHz radio battery.
Wiring with polarized connector, to assure proper connection to the printed circuit board.
The cell is fastened inside the meter; it cannot be replaced and it is protected by metrological seals.
