Mounting the VTR1

5.1

Heatsinking

The approximate heat dissipation of the VTR1 can be calculated as follows:

HD = 0.25 * BR * PW * TF + 2

Where:

HD

Heat dissipation (W)

PW

Strobe pulse width (seconds)

TF

Maximum trigger frequency (Hz)

BR

Brightness of the light output (%)

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 VTR1 below 70
