Power Supplies
We offer two different types of power supplies for the 5403 electromagnet; unipolar and bipolar.

Elgar Electronics Power SupplyWe 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:
DLM40-75EM9E - Power Supply, 40V, 75A, unipolar, 0.05% / 8hrs, IEEE-488. Input voltage: 180 - 264V, 50/60Hz, 16A, 1P.
DLM40-75E - Power Supply, 40V, 75A, unipolar, 0.05% / 8hrs, analog programming. Input voltage: 180 - 264V, 50/60Hz, 16A, 1P

Kepco BOP 20-20MFor 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:
BOP20-20DL Power supply, 20V, 20A, bipolar.
BIT-4886 IEEE-488 interface for Kepco BOP power supplies, 16-bit.

5971-160 Current Reversal SwitchIf 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.
