D-Link DPS-500A Redundant Power Supply

Description

Manufacture # D-Link | Model # DPS-500A

It's redundant power supplies (RPS), designed for use with switches D-Link. RPS implemented in a robust metal housing with a connector for connecting them to the AC or DC power supply (depending on model) and a connector for connecting to the internal power supply switch. Redundant Power Supply (RPS) is a low-cost device that allows to provide uninterrupted power in the event of an unexpected failure of the internal power supply switch, which may result in a shutdown of the switch devices connected to its ports, or the entire network. Providing necessary for the output power switch, the RPS can improve the reliability of the device.

Features:

• Deployment of a DPS series device does not require any change in the configuration of the LAN switch. Each RPS is equipped with a universal internal power supply and can be connected to any AC power source from 90 V AC to 264 V AC, 47 Hz to 63 Hz through a standard AC power cable.
• Each D-Link RPS is equipped with an integrated detection circuit that continuously monitors the switching device’s internal power supply. In the event of a power interruption, the redundant power supply is immediately triggered so that the LAN switch and its connected devices can continue providing service. This results in a more reliable network infrastructure and protects the network from a single failure of a network device power supply.
• The DPS-200A, DPS-500A, and DPS-500DC redundant power supplies (RPS) are designed to conform to the wattage requirements of D-Link’s Ethernet and Gigabit switches. They are external RPS units enclosed in solid metal cases with sockets for AC or DC power sources on one end, and connect to a switch’s internal power supply on the other end. They provide a n affordable, simple solution to the problem of an inadvertent failure of the internal power-supply of an Ethernet switch, which can result in the shutdown of that switch, the devices attached to its ports, or an entire network. Supporting full output power for the switch, these redundant power supplies can maximize the power availability of the switching device.
