Information about circuit load
The system circuit load is the sum of the light source’s power consumption 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). Information regarding the maximum number of HF-ballasts per miniature circuit-breaker can be found on Fuse Protection page within the technical section.
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.
