Example 1:
Transformer and filtering board are mounted on the ceiling tube, emergency supply 25.0 V D.C. under load (refer-
ence value) on the terminal connection of the ceiling tube.
The transformer tap corresponds to 230 V supply voltage, 3 / 6 for the primary connection and 8 / 9 for the sec-
ondary tap.
Example 2:
Transformer and filtering board are mounted in the wall box, emergency supply 25.5 V D.C. under load (reference
value) on the terminal connection of the ceiling tube.
The wire’s voltage drop is 2 V.
The transformer tap corresponds to 230 V supply voltage, 3 / 6 for the primary connection and 8 / 10 for the
secondary tap.
Attention:
If the transformer and the filtering board are mounted separately, the wire’s voltage drop between the filtering
board’s output and the terminal connection of the ceiling tube has to be taken into account accordingly.
If the transformer is mounted on the ceiling tube, the smallest secondary tap (21.5 V) has to be chosen. After the
rectification on the filtering board, the above mentioned value corresponds to a D.C. voltage of ca. 24.0 V under
load.
