The Power Supply
The 5051 is intended for 5088 consoles or 5285 vertical frames. There are two +/- 24V power supply options; The 5-way supply is designed to sit in the bottom of a rack, and the 25-way supply is a 2U enclosure. The external +/- 24V supply provides exceptionally clean power, and reduces heat build-up within modules associated with DC-DC up-conversion.
