RTCC LED lighting controllers - User Manual

Lighting setup
The rating of the light must be set by the user. This rating is the supply to
the lighting that should be used to get 100% continuous brightness from
the light. The RTCC is compatible with both current and voltage rated
lighting.
You must enter the rating for the light before connecting it to the controller,
or if you replace it with a different type of light. If a light is replaced with the
same type of light then the previous rating still applies.
Consult the specification or labelling for the light. For commercially
available lighting modules, if a voltage and current rating is given, use the
current rating. If a voltage and wattage rating is given, use the voltage
rating. Otherwise use the current rating. For ‘homemade’ lights using
single LEDs or arrays of LEDs use the current rating from the
LED datasheet.
You can set the current rating from 0.01A to 3A in steps of 0.01A, and you
can set the voltage rating from 12V to 36V in steps of 1V.
When you connect a voltage rated light, the RTCC automatically senses
the current rating of the light.
Voltage and current rated lights are both driven with a constant current.
This gives better brightness stability and allows the RTCC to prevent the
light being driven with too much power.
To set the rating of a light on RS232 or Ethernet versions of the RTCC
controller, use the
VL
command (see
), or use the internal webpages on Ethernet versions of the
RTCC controller (see
Section 11, Webpage configuration (RTCC420)
).
