Low Voltage Power Supply Project
200VDC HPS1 power supply TESLA
The input for the
TileCal power system is 200V DC voltage that is converted from three phase mains
3x230V~. For this purpose 22 custom made bulk power supplies HPS1 are needed.
One HPS1 unit contains three output power channels delivering 200VDC/8.5A
(1.7kW), each power unit can therefore supply 12 finger LVBOXes supplies. The
HPS1 are not radiation tolerant and therefore are deployed in USA15 control room
of the ATLAS cavern. They were developed at TESLA Company, Prague, Czech
republic.
