Power Supplies and Current Reversal
We offer several different power supplies for the 3472 electromagnet; the Ametek switch mode, and the Danfysik high stability linear.
The Ametek switch mode power supplies feature a stability of 0.05% over 8 hours and they are available with an optional IEEE-488 interface. Order part numbers:
Input: 187-242V, 21A, 47-63Hz ac, 3 phase
SGA60/83C-0AAA - Power supply, 60V, 83A, unipolar, 0.05% / 8hrs.
SGA60/83C-1AAA - Power Supply, 60V, 83A, unipolar, 0.05% / 8hrs, IEEE-488 interface

SGA60/83D-1AAA - Power Supply, 60V, 83A, unipolar, 0.05% / 8hrs, IEEE-488 interface
For applications that require a bipolar power supply, we offer the Kepco BOP series. They feature stability of 0.02% over 8 hours, and an optional IEEE-488 interface may be installed either by GMW, or by the user at a later date. The 5403 requires two of the Kepco BOP 20V, 20A, supplies wired in paralllel to acheive 20V, 40A.
Order part number:
BOP 20-20M Power supply, 20V, 20A, bipolar.
BIT-4886 IEEE-488 interface for Kepco BOP power supplies, 16-bit.
For applications that require a high stability power supply, we offer the Danfysik 858 series linear power supplies. They feature a stability of 10ppm over 8 hours, 18 bit current setting, 16 bit current readback, a built-in IEEE-488 interface, and an internal current reversal switch.
Order part number:
858-70A/65V - Power supply, 65V, 70A, unipolar.
If field reversal is required when using a a unipolar Power Supply, we offer the 5971-160 Current Reversal Switch. This Switch provides a safe way of reversing the magnets current under either manual or computer control. The USB Interface also provides control fo the Power Supply current, and readback of the Power Supply current and voltage. It will also provide field readback from a Senis Field Transducer if installed.

Pole Spacers
Higher field uniformity may be achieved with a set of precision ground pole spacers. These spacers come three to a set and include a delrin spacer ring assembly to accurately locate the spacers. This ring assembly may be machined to hold experiment fixtures, and may even include a set of Bias Coils.

11900370 - Spacer Assemby, for 75mm poles, with bias coils.
11900380 - Spacer Assemby, for 100mm poles.
11900390 - Spacer Assemby, for 100mm poles, with bias coils.
Bias Coils
Bias Coils are used for two different applications with electromagnets; obtaining a 'zero' field, or superimposing a modulated signal on the field.
For achieving a zero field, the bias coils are used with a fixed DC power supply, and set to generate a 'negative' field when the main magnet power supply is stitched off. The the main magnet power supply may then be programmed to any field from zero upwards to the magnet power supply maximum.
For field modulation, the bias coils may be used with a low power bipolar power supply such as the Kepco BOP 100-1M. Note that our magnets are of a solid yoke design, so the modulation frequency will be limited to less than 30Hz.
