Magnet Power Supplies

The opportunity is for the provision of magnet power supplies for Fermilab. The power supplies must meet specific technical specifications, including operating parameters, rated parameters, and design requirements. The design must be a high-precision, low-ripple, bidirectional constant-current supply with long-term reliable operation. The power supply shall adopt a modular structure and incorporate EMC pre-compliance design. The opportunity requires the supplier to provide a quote for the exact item(s) and specification(s) listed in the attached documents. • The power supply must be able to meet the specifications, including operating parameters and rated parameters. • The design must strike a balance between output current performance and power factor, as well as other grid characteristics. • The power supply shall adopt a modular structure, with the following main circuit topology: AC–DC source, DC–DC converter, hardware protection and interlock, coil temperature protection, load parameter sampling, EMI filter, and high-precision digital power controller. • The power supply must be able to operate continuously without requiring manual recalibration during long-term use. • The power supply must provide an independent cross-check of load current through an auxiliary sampling channel for enhanced reliability.
