LED zone controller
LED zone controller based on TCM 330 acts as the central receiver and processor of input
data (commands or status messages) from linked components.
Based on this input data, it determines the appropriate lighting level and sets the output
signals connected to the LED Driver accordingly.
The LED driver then adjusts LED supply voltage and supply current such that the com-
manded light level is achieved.
The typical system setup for a line powered LED zone controller is shown below.
The LED zone controller receives wireless input in the form of EnOcean radio telegrams us-
ing its antenna.
Power is provided by means of an AC power supply input or alternatively a DC input as de-
scribed in chapter 3.5.1.
LED zone controller controls the LED driver using two signals:
n
Driver control signal (0-10V Output)
LED zone controller signals the required dim level to the LED driver using a standard 0-
10V interface where 0V means no illumination (OFF) while 10V means maximum illumi-
nation.
n
Driver power supply (Relay Output) – optional feature
LED zone controller can control line power supply (120V) to the LED Driver by means of
an integrated relay. In such setup, power to the LED driver would be provided only if the
light is commanded to be ON.
Based on these two signals, the LED driver will then set the right supply voltage and supply
current to the LED string in order to achieve the requested illumination level.
