Power
Supplies and Current Reversal
We offer several different power supplies for the 5414
electromagnet; the Elgar switch mode, and the Danfysik
high stability linear.
 The
Elgar 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:
P86C-100200 - Power supply, 100V, 200A, unipolar.

 For
applications that require a high stability power supply,
we offer the Danfysik 853 series linear power supplies.
They feature a stability of 1ppm over 8 hours, 18 bit
current setting, 16 bit current readback and an optional
IEEE-488 interface. Order part number:
853-140A/140V - Power supply, 140A, 140V, unipolar.

Magnet
Current Cables
We take the trouble out of connecting your magnet to the
power supply with a wide variety of pre-terminated cable
assemblies.

Axial
Holes
For optical experiments or other applications where an
axial hole in one or both poles is required, GMW can provide
the poles with the hole pre-drilled to your specifications.

Cabinets
 RC-351930
Optima 19" EIA rack cabinet. This handsome half-height
19" rack cabinet provides ample space for your power
supply, reversing switch, and other instrumentation.
It is two-tone gray, and is supplied with lift off side
panels, castors, and a door mounted on to the back. The
door includes two line powered cooling fans to help draw
hot air out of the rack. It does not include filler panels
and support angles.
Accessories:
P-0119 - Filler panel, 1U, light gray.
P-0319 - Filler panel, 2U, light gray.
P-0519 - Filler panel, 3U, light gray.
P-0719 - Filler panel, 4U, light gray.
P-0819 - Filler panel, 5U, light gray.
SA-30 - Support Angle Pair.
HW-1 - Hardware kit, screws and washers, set of
100.

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.
