The CP290-01 is a 1000 W power supply module engineered for the Astronics/EADS/Racal 1261B VXI mainframe. This pluggable assembly mounts directly to the mainframe backplane and delivers stable DC power across multiple voltage rails under demanding operational conditions. Input acceptance spans 90 VRMS to 250 VRMS at 45–440 Hz, enabling global deployment. The supply generates 2000 W of available DC power for the system, with primary outputs of +5 V @ 80 A and +12 V @ 17 A (IMP ratings), plus fused auxiliary rails at +5 V, +12 V, and +24 V @ 1 A each. All rail voltages are monitored and reported through a rear connector.
