In the absence of such markings, NIST will assume unlimited rights to all technical data submitted. BACKGROUND The Functional Nanostructured Materials Group is working to advance measurement science and standards in magnetic thin films and magnetoresistive random access memory technologies. A commercial H-frame electromagnet is used to generate applied fields driven by a commercial ER 083 power supply unit. This power supply unit is a 200 V, 60 A (12 kW) power supply and has reached the end of life. In order to continue using the electromagnet, a compatible power supply is required to deliver current-regulated power to the electromagnet with high stability for precision measurements of magnetic thin films and Magnetoresistive random access memory technologies under well-controlled fields. Such an electromagnet requires an electromagnet power supply system, including a current-regulated power supply, an embedded Hall-effect based Gaussmeter, and feedback-regulated control of the current delivered to the electromagnet to achieve stable field control. DESCRIPTION OF REQUIREMENT The Contractor shall provide one (1) electromagnet power supply system that meets all technical specifications identified below: One bipolar current-regulated power supply unit (unit) with zero-crossing continuity (no use of current reversal switches), with at least 12 kW output power, at least 200 V output voltage and at least 60 A output current. Longterm drift of the current shall be less than 50 parts per million (ppm) over 8 hrs assuming constant temperature, and less than 5 ppm per degree Celsius.Serial or ethernet control of the power supply unit, with integral conversion of the desired set field to better than 18 bits and digitization of analog signals to better than 24 bits Water cooling of the unit; three-phase, 208 V power input A digital Tes…
