23 Oct 1997 Instrument power specifications must take into account not only instrument requirements, but also the context, which in this case means Chilean standards and practices at other telescopes on Cerro Pachon, ie Gemini.
Frequency converters are very expensive and unnecessary.
WYE In cable wrap only for future expansion. The KVA rating defines what current the circuit can supply but does not authorize the instrument to dissipate this number of watts on a continuous basis. Heat dissipation must be minimized to control the cost and size of the heat extraction system. Instrument power is generally dominated by detector electronics for science, guiding and wavefront sensing. These tend to scale with peak readout bandwidth, and to be independent of telescope aperture.
