Mounting the VTR4
The VTR4 has 4 off M8 mounting studs. These should be fitted to the VTR4
optional mounting bracket, or through 9.0mm diameter holes in the
user’s
infrastructure and fastened with nuts that are tightened to a maximum of
15Nm. If larger diameter holes, or a higher torque is used, then there is a risk of
damaging the VTR4.
5.1
Heatsinking
The approximate heat dissipation of the VTR4 can be calculated as
follows:
HD = (36 x BR x PW x TF ) + 2
Where:
HD Heat dissipation (W)
BR Brightness of the light output (%)
PW Strobe pule width (seconds)
TF Maximum trigger frequency (Hz)
Without any heatsinking, the internal temperature of the VTR4 rises 0.45°C per
Watt of heat dissipation. Given the range of ambient temperatures and
radiated sunlight, the installation must provide enough heatsinking on the rear
surface to keep the internal temperature of the VTR4 below 70°C.
