Superconducting magnet electronics
Superconducting magnet electronics
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.
Features and benefits:
- 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
