If the power regulation is good but the power line disturbance analyzer shows transient voltages, an isolation/noise-suppression transformer can resolve the problem. For both transient and regulation problems, consider the use of power conditioners to control these problems.
CAUTION
Any conditioning device installed with the MS must be able to handle the potentially high currents that are drawn during the initial startup of the system. The maximum system inrush (start) current for one forepump is 12 A with an average duration of less than 1 second. Therefore, this initial energy demand from the ac power line is very low.
When the line voltage is free from voltage sags, surges, and impulses but is more than 10 percent outside of the voltage specifications, a buck/boost transformer can lower (buck 10 percent) or raise (boost 10 percent) the line voltage as appropriate for the rated voltage.
CAUTION
Instruments installed in areas with 208 VAC power can experience voltage sags during high use periods that might place the line voltage below the operating parameters discussed in this section. In this case, protect the instrument by ordering a Buck/Boost Transformer Kit (P/N OPTON-01460) to ensure that power stays within the specified parameters.
