Product description

The Lake Shore 625 superconducting magnet power supply from the United States is an ideal power supply for small to medium-sized superconducting magnets, used for highly sensitive material research applications. 625 can also be used in practical applications for large-sized superconducting magnet power supplies and some general power supplies. Lakeshore focuses on the performance requirements of most users who require magnets. 625 has the characteristics of high precision, low noise, safety, and convenience.


Accurate lateral measurement is generally defined as the continuous smoothing operation performed at high set resolution and low drift. Achieving these goals simultaneously drives a challenging load, such as a superconducting magnet, requiring a unique solution. The maximum output current of 625 at the rated compliant voltage of 5V is 60A, acting as a current source or receiver, completing true four quadrant operation. The output structure of the power supply is equipped with analog control to achieve smooth operation and low drift. Careful mixing of analog and digital circuits provides a high setting resolution of 0.1 mA and flexible output programming.


Lakeshore chooses a moderate 300W linear input and output power for 625. Linear operation eliminates the radiated radio frequency (RF) noise of the switching power supply, reducing its overall output noise and the noise radiated to surrounding electronic devices.


Considering the issues of energy storage and refrigerant in superconducting magnets, safety design should never be an afterthought. 625 includes various hardware and firmware with protective features to ensure the safety of magnets and power supplies. For the improvement of operator safety, the power supply design complies with CE certification safety requirements, including low voltage official instructions and electromagnetic compatibility (EMC) official instructions.


Instrument users trust Lake Shore for its convenience and ease of use. 625 includes necessary functional features for managing a superconducting magnet, such as persistent mode heater output, calculated magnetic field readings, current rate of change, and real-time superconducting detection function. Integrated computer interfaces for automation of magnet systems. 625 is a superconducting magnet control solution.
