XTR INNOVATIONS TO ENABLE LONG RUNS
There are numerous challenges involved with creating long runs of high output LED fixtures,
most notably concerning control and power; in response, Acclaim Lighting engineers have
created ingenious solutions to ensure consistent and reliable operation:
CONTROL
Long distances and high fixture counts are detrimental even to such a robust control
solution as DMX; usually a maximum of 32 fixtures is possible before the signal-to-noise ratio
threatens to affect operation. That is why every fixture in the Acclaim Lighting XTR range
acts as its own signal isolator and conditioner before passing the control feed down the line.
The result is a clean, reliable and [still] industry-standard control solution right to the end of
the line. Additionally, as each fixture supports RDM, the passage of conditioned and isolated
signals is fully bi-directional.
POWER
Every XTR fixture conditions its own power using a high-efficiency internal switched-mode
power supply. A well known feature of such devices is their behavior during the fractions
of a second after power is first applied, known as 'in-rush current' . This is when their internal
components top themselves up with charge to progress from empty to a working state,
which causes a very brief rise above their usual maximum consumption level. If you place
many such devices on the same power line and activate them all simultaneously, their
collective temporary overruns can easily swamp an otherwise perfectly adequate power
feed, causing breaker trips.
To reliably solve this issue, the common high voltage power rail running through the XTR
cables is not a 'dumb run' but rather a managed resource. Every XTR fixture energizes itself
fully before passing power through to the next fixture in the chain. The delay at each fixture
is measured in milliseconds, but it is sufficient to ensure that the installation as a whole
never stresses the main power feed during the initial startup.
OPTIONAL WIRELESS CONTROL
Using optional Acclaim Lighting Aria modules it is possible to wirelessly transmit a DMX
signal to a Linear XTR run over distances up to 2600 feet (792m):
