Electrical Data
The luminous signs are powered by series circuits through isolating transformers compliant to FAA
Specs FAA L830-L831. The power consumption of the LIMS signs is reported in Table 6: for all sign
type the power factor is higher than 0.9.

Table 6: Power consumption at maximum luminance
The minimum size of the isolating transformer depends on both the sign type and the selected
power supply (i.e. the number of current steps provided by the CCR), according to Table 7 and
Table 8.
