Information about circuit load
The system circuit load is the sum of the light source’s power con-
sumption and losses in the associated control gear. An installation
must be designed to take into account the starting current as well
as the total power consumption. Normally it is the starting current,
and not the system output, that dictates how many HF-ballasts
can be connected to a miniature circuit-breaker (MCB). Informa-
tion regarding the maximum number of HF-ballasts per miniature
circuit-breaker can be found on Fuse Protection page within the
technical section.
The system and lamp wattages for a number of dierent
HF-ballasts are presented below. As standard Fagerhult’s luminaires
are equipped with warm start HF-ballasts, where pre-heating of
the cathode is either reduced or ceases completely when the light
source is ignited. This function saves energy.
Note: Figures may vary for other HF-ballasts. The stated values are
examples and are rounded to the closest integer. Development of
HF-ballasts is ongoing and defined values may be subject to change.
The power factor, cosfi, lies between 0.95 and 0.99 for luminaires
equipped with HF-ballasts.
