This document is a Procurement Request (PR) for TDK/Lambda power supplies to be used for electric propulsion system testing. The requested items include 6 units of TDK/Lambda G600-12.5-3P208 power supply, 1 G/P-4U-60-1500V series/parallel kit, 6 units of GH40-25-U power supply, and 2 G600-2.8 power supplies. Each power supply has specific technical specifications, such as rated power, voltage ranges, input/output characteristics, and mounting formats.

The power supplies will be used in Bldg 301 vacuum facilities to test electric propulsion systems for AEPS, PPE, and SSEP programs. They are being procured as spares for existing test racks and power consoles, with requirements for consistent power interface and control interfaces. The procurement is justified by the need to replace currently used power supplies and ensure electrical stability when testing electric propulsion thrusters that generate highly dynamic plasmas.
