MODEL 12A-LI"
" Q " Line transistorized power supplies, used in a complete P E M low impedance magnet system, yield unparalleled homogeneity and regulation. In sizes from 5 to 200 KW (larger sizes on request), they are current regulated and stable to 1 part in 100,000. Optimum regulation, minimum drift, and maintenance freedom are "built in" by P E M through use of temperature-controlled shunt and superb components throughout. Easy to operate: double closed loop design and clamp circuits eliminate damage through misuse. Conservative design includes water-cooled heat sinks to minimize heat dissipation into the room.
