Spectrographic Instruments
Use VIPAC AC-DC Power Supply Configured on PowerBench
The James Webb Space Telescope, to be launched in 2014, will be in an orbit synchronous with Earth, which will act as a shield to block infrared radiation from the Sun. The telescope will use its near-infrared spectrograph to observe the most distant objects in the universe. At the other end of the scale, spectroscopy is used to analyze microscopic samples of cells and proteins. Spectrometers are even used during surgery to monitor respiration and anesthetic gases in real time.
Our customer is a leading manufacturer of spectrographic instruments for use in such applications as astronomy, pharmaceutical and chemical manufacturing, and nanotechnology. For the current application, they make instruments that monitor chemical levels in various pharmaceutical and petro-chemical processes. These instruments employ lasers and cameras that need to be operated from voltages of 12 Vdc and 5 Vdc.
The subject application required AC inputs of 115 V and 230 V and the two DC outputs, 12 V at 200 W and 5 V at 50 W. The Vicor application engineer configured a VIPAC Power system for them using the PowerBench VIPAC Design Center. The autoranging VIPAC AC-DC power supply provides built-in EMI filtering (EN55022 compliant) that ensures the quiet operation desirable in these sensitive instruments. With no NRE, the cost of customization was decreased to that of standard solutions. Other benefits for them were the low profile of the VIPAC and the fact that it could be attached to the heat sink and the heat sink can be mounted outside of the chassis for better heat dissipation.
