Magnet Power Supplies

The power supply units of the Heinzinger PCU series are optimised for use as power supplies for magnets. The power supplies provide high-precision DC voltage with excellent current stability and extremely low ripple.These units are available in the typical voltage categories as power supplies for magnetic applications and make use of a modular design. Various currents between 100A and 340A are available for each power supply. In applications requiring more power, the power supplies can be used in master/slave mode in parallel. The switching power supply technology in use makes them extremely efficient. Pole reversal via polarity-switching-unit optionaly.

For high power magnet applications (like Dipole-magnets) we can offer PTN3p-series power supplies, tuned to the application "magnet power supply".
