Lake Shore 648 Series Electromagnet Power Supply


The Model 648 electromagnet power supply is a robust, fault-tolerant 9 kW supply optimised for powering large 7 or 10 inch research electromagnets. It is specifically designed for high precision laboratory use requiring extremely low electrical noise. The linear design removes undesirable higher frequency noise typical of switch mode power supplies. Eliminating the need for external switching or operator intervention to reverse current polarity, the Model 648 uses convenient bipolar, 4-quadrant operation. It is capable of supplying ±135 A/±75 V to a nominal 0.5 Ω, 0.5 H load. The Model 648 is built to last with a rugged design, integrated fault protection, and a simple, clean interior electronic design.


  • Bipolar, linear, 4-quadrant output
  • ±135 A/±75 V, 9.1 kW
  • Low noise
  • 1mA of programmed current resolution
  • Analog programming and IEE-488 and USB interfaces
  • Built-in fault protection
