Consumption and sizing of cables
The calculation of the consumption of the various field devices, added to the consumption of
any other 12V powered devices is fundamental to establish how the system needs to be
powered. In particular, if the total of the power as above is less than 30W+/- 1W it is
possible to power the system directly from the control unit if this is fitted with the battery load
and protection circuit (UCE40MPA-CPB order code). For higher powers a UPS
(uninterrupted power supply) unit must be provided. With reference to the main detectors,
the power and the current of each device are shown on the table below:
