We offer two different types of power supplies for the
5403 electromagnet; unipolar and bipolar.
offer Sorenson unipolar supplies suitable for applications were a DC field is
required. They feature a stability of 0.05% over 8 hours
and they are available with an optional IEEE-488 interface.
Order part numbers:
- Power Supply, 40V, 75A, unipolar, 0.05% / 8hrs, IEEE-488. Input voltage: 180 - 264V, 50/60Hz, 16A, 1P.
- Power Supply, 40V, 75A, unipolar, 0.05% / 8hrs, analog programming. Input voltage: 180 - 264V, 50/60Hz, 16A, 1P
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:
20-20ML Power supply, 20V, 20A, bipolar.
IEEE-488 interface for Kepco BOP power supplies, 16-bit.
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.
