High-precision current sourcefor high current at low voltage,up to 13 kA / 18 V
Compact, modular designin 19-inch cabinets
Basic structure:Chopper – transformer –3x rectifier
Water coolingfor high power density
Redundancy using multipleparallel-switched currentsources allows maintenanceduring operation
2 different systems
