Bipolar Power Supply.

Linear bipolar magnet power supplies utilize fixed diode rectifier which convert AC to DC and regulate output using precise transistor stage

Bipolar operation provides smooth transition through zero and smooth field generation that is nearly free from offending electromagnetic signature.  High sensitivity experiment requires clean field background which allows greater resolution and finer detail in result and data drawn from experiment.

The electromagnet power supply is a linear, bipolar current source providing true 4-quadrant output, eliminating the need for external switching or operator intervention to reverse current polarity. Internally programmed output provides 20-bit resolution, while externally programmed output provides unlimited resolution.


  • Bipolar, linear, true 4-quadrant output
  • ±70 A/±35 V, 2.5 kW
  • ±100 A/±50 V, 5.0 kW
  • ±135 A/±65 V, 8.8 kW
  • Modulated to frequencies up to 0.17 Hz at ±70 A
  • Low noise
  • 0.1 mA of programmed current resolution
  • Analog programming and IEEE-488 and RS-232C interfaces
  • Built-in fault protection
  • Compat design
