Scientific Magnetics partners with 3rd party electronics manufacturers to supply the very best in system electronics, including superconducting magnet Power Supplies, Temperature Controllers/Monitors and Cryogen level Meters. Below is an example of our standard PS120- 10V Power Supply.


  • Modular design, allowing master-slave operation for higher current models
  • An integral electronic polarity reversing switch option can be fitted
  • Independently fail safe protected, air cooled and has an internal high stability shunt for greater accuracy
  • IEEE-488 and optically isolated RS232 operation with short-form codes for ease of automatic computer operation and confirmation of the operational status shown by a backlit liquid crystal display on the front panel
  • Adjustable output for persistent switch heater
  • Fully configurable from the front panel or using the remote interface
  • With optional reversing switch
  • Automated quench monitoring and safe shut-down
