Arista APS-DR1048-24 Switched-Mode DC Power Supply

Arista APS-DR1048-24 is a 24 VDC switched-mode power supply designed to power Arista networking equipment that requires a dedicated 24-volt DC source. It accepts a wide input range, 100–240 VAC or 120–370 VDC, enabling installation in environments with either AC mains or high-voltage DC delivery, which can simplify deployments where multiple power sources exist or where redundant power schemes are used. The unit provides up to 48 W of output at 24 V, which corresponds to about 2 A of current, allowing it to support devices that draw modest continuous 24 V loads and providing headroom for startup surges typical of network gear. As part of the Arista APS family of power supplies, the APS-DR1048-24 is designed for reliable operation in networking deployments, combining a wide input range with a fixed 24 V output to support dependable DC power for compatible Arista devices.
