Electronic controller for LED-lamps
LEDControl4 V2
Characteristics
LEDControl4 V2
converts 4 analog input voltages into 4 pulse width modulated (PWM) signals (Open-Drain) and includes drivers for the direct
connection of LEDs (max. 5 A in total). Furthermore with
LEDControl4
external LED-drivers with PWM-input can be controlled. In order to
protect the connected
ProfiLux
from possible interferences, the input side is galvanically isolated from the output side through optocouplers.
In the delivery status, for 0% PWM the transistors are insulating (output is high-resistance), for 100% PWM the output is permanently pulled to
minus potential. The polarity of the PWM can be inverted. Through this you achieve that for 0% PWM the outputs are permanently pulled to
minus potential and for 100% PWM the outputs are high-resistance. Through a new inversion you can switch again to the original state.
LEDControl4
can produce „flashes“ during a thunderstorm simulation in
ProfiLux
. During a flash the PWM-signal is set for a short time to 50%,
75% or 100%, independently from the belonging analog input. Flashes can be output at channel 3 and channel 4, the flashing behavior can be
set, see below. Not all L-ports are suited for the generation of a flash. Presently the onboard interfaces of
ProfiLux
and the interfaces in the
ExpansionBox
support the flash function.
According to the connection,
LEDControl4
can be used for the operation with LED-lamps or with LED-drivers.
