Grass Valley 8900 Frames Gecko 2009 - Manual (Page 32)

32 Gecko Frames — Instruction Manual
Section 1 — Gecko 8900 Series Frames
Calculating Frame Power
To calculate the power required for your frame, you must total all the
power dissipated for each individual module.
Table 3 provides the power dissipation for many of the modules compat-
ible with the 8900 Video and Audio frames. For newer modules not listed,
refer to the Specifications table in the specific module instruction manual.
Two examples of power calculations are shown in Table 4 and Table 5 .
The total frame power required is less than 30 watts; therefore, the convec-
tion frame may be used.
