D-Link DPS-500DC – 140W DC Redundant Power Supply Unit for D-Link Ethernet & Gigabit Switches with Standalone / Chassis Installation Support
Overview:
• The D-Link DPS-500DC is a DC Redundant Power Supply Unit designed to provide backup power for compatible D-Link Ethernet and Gigabit switches.
• It provides the same output power class as the DPS-500, supporting up to 140W output power, but it connects to a DC power source instead of an AC source.
• The unit includes an integrated detection circuit that continuously monitors the connected switch’s internal power supply.
• If the switch’s internal power supply fails or power is interrupted, the DPS-500DC is immediately triggered to keep the switch and connected network devices operating.
• The DPS-500DC can be installed as a standalone redundant power supply unit or mounted inside a DPS-800 / DPS-900 chassis for organized rack-based deployment.
