LC60DS-DA-700-1400 LED driver implements amplitude dimming technology across whole dimming range. Amplitude dimming offers
the best available technology for dimming the light output in an accurate and flicker-free way to ensure high quality lighting in even
the most demanding situations such as camera recording applications. Amplitude dimming technology complies with IEEE 1789-2015
recommendations of current modulation to mitigate health risks to viewers.

Total continous current of the drivers and installation environment must always be considered and taken into calculations when installing drivers behind
miniature circuit breaker. Example calculation of total drivers amount limited by continous current: n(I
cont
)
= (16 A (I
nom,Ta
) / “nominal mains current with full
load”) x 0.76). This calculation is an example according to recommended precautions due to multiple adjacent circuit breakers (> 9 MCBs) and installa-
tion environment (T
a
30 degrees); variables may vary according to the use case. Both inrush current and continous current calculations are based on
ABB S200 series circuit breakers. More specific information in ABB series S200 circuit breaker documentation.
NOTE! Type C MCB’s are strongly recommended to use with LED lighting. Please see more details in “MCB information” document in each driver product
page in “downloads & links” section.
