2.3 Reference standards
The constant current regulators are manufactured in accordance with the following standard:
●
IEC 61822, Edition 2.0: Electrical installations for lighting and signalling in airports and heliports - Constant
current regulator.
●
AENA DIN/DNYM/PPT/002-05/13: Technical specifications for constant intensity controllers.
2.4 Nb. of steps
The constant current regulators can be equipped with a number of steps varying from 1 to 8, each configurable in
the range 1.8-6.6 A, to meet different end-user requirements.
According to IEC 61822, the nominal output current range is:
●
Type 1: from 4.8 to 6.6 A
●
Type 2: from 2.8 to 6.6 A
The table provides the normalised CCR pre-settings. These settings can be modified in accordance with the
requirements of an airport.

The tolerance is ± 0.1 A for each adjustment within the nominal output current range.
The constant current regulator can supply a low-current heating brightness level (preferably
1.8 A), which is used to remove condensation from inside the fixtures without switching on
the lamps.
The symbol for the local setting is B0.
