8.1 Electrical Power Requirements
When planning the electrical power requirements of your site make provision for extra
equipment which you may install, e.g. personal computers, workstations, air conditioning
systems, etc.
Each AVANCE
TM
cabinet (except NanoBay) comes supplied with four spare electrical outlets
(230V/10A) which can be used to power standard ancillary equipment. Two outlets are
designed to power the NMR Workstation and Imaging cabinet (optional). This leaves two
spare outlets for accessories such as the Sample Changers etc. The table in this section lists
the power requirements of other equipment which, because of their large power consumption,
require power sources separate to that of the AVANCE cabinet.
Other Power Requirement Considerations
• For installation of the AVANCE system a 230V / 16A outlet is needed for the turbo-pumps,
as well as an additional 230V / 16A outlet for the magnet power supply (during installation
and service).
• A TwoBay with Solid Accessory 600/700 MHz can be approximated to a standard TwoBay
plus High Power cabinet and so the total power requirements is 5 kW.
• The power requirements for the CP-MAS will depend on the amplifiers that are used. The
control unit itself will not use more than 100W.
• If line voltage fluctuations exceed -5% to +10% a voltage stabilizer must be used. The
lifetime of the various electrical components in the spectrometer will also be lengthened
when a voltage stabilizer is used. Contact your local Bruker BioSpin office for more
information on voltage stabilizers.
• Where total interruption of power occurs frequently, you should consider installing a UPS
(Uninterruptable Power Supply) possibly linked to an emergency back-up generator. This
is particularly advisable when long-time experiments are to be run.
• The power supply to the spectrometer must be "clean" (no spikes), i.e. it must not share
with air conditioners, compressors, etc.
• All grounding for mains in the lab must be connected together to avoid differences in earth
potential.
