Lake Shore 643 Series Electromagnet Power Supply

The 648 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. The Model 643 is capable of supplying ±70 A/±35 V to a nominal 0.5 W, 0.5 H load, and the output can be modulated from an external source to frequencies up to 0.17 Hz at ±70 A. Internally programmed output provides 20-bit resolution, while externally programmed output provides unlimited resolution.

Features:

• Bipolar. linear, true 4-quarant output
• ±70 A/±35 V. 2.5kW
• Can be 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
• Compact design
