Result
All the values meet the requirements. The components are mutually compatible.
With 2 modules a luminous flux of 3,713 lm will be achieved.
To produce a luminous flux of 3,000 lm, the two LED modules
must be operated with a forward current of 700 mA.
_
The LED Driver can be set so that it delivers precisely this value
of 700 mA as the output current.
_
The output current of the LED Driver including tolerances (700
mA + 3 % = 721 mA) is less than or equal to the max. DC forward
current of the LED module (1400 mA).
_
The voltage range of the LED module (2 x 43.6 V = 87.2 V; 2 x
49.8 V = 99.6 V) lies completely within the voltage range of the
LED Driver (45 - 107 V).
_
The Output LF current ripple (5 % of output current plus
tolerances: [700 mA + 3 %] x 1.05 = 757,05 mA) of the LED
Driver is less than the max. permissible LF current ripple of the
LED module (1800 mA).
_
The max. output current peak of the LED Driver (700 mA + 40 %
= 980 mA) is less than the max. permissible peak current with
which the LED module can be operated (2,000 mA).
_
The power draw of the LED module (64.8 W) is less than the
output power of the LED Driver (75.0 W).
