Easy and Flexible Deployment

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.

Affordable Redundant Power Backup

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.

Integrated Detection Circuit

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.
