Description

The PWR-D4-3041-AC-BLUE is a 3000 W hot-swappable 1RU power supply for Arista 7800R3 and 7800R4 series modular chassis. It is the blue-handle ATS variant, built for high-density data centre spine and AI/ML spine switches that need redundant, serviceable power.

An automatic transfer switch lets this module accept either high-voltage AC or HVDC input. Input is 2x 200-277 VAC or 2x 240-380 VDC at 16 A, delivered through 2x SAF-D-GRID 400 connectors, with AC input frequency of 50/60 Hz. Efficiency is rated at 94.5%, 80 PLUS Platinum class, and output power is 3000 W. This makes it a good fit for sites using 277 VAC or 380 VDC power distribution.

It is compatible with the Arista 7800R3 series (DCS-7804R3 to DCS-7816LR3) and 7800R4 series (DCS-7804R4, 7808R4, 7812R4 and 7816LR4) chassis. The sibling PSUs PWR-D1-3041-AC (200-240 VAC only) and PWR-D2-3041-DC (-48 to -60 VDC) cover other power feeds.
