D-Link 156W modulaire redundante voeding

The D-Link DPS-500A redundant power supply delivers backup power for compatible D-Link Fast Ethernet and Gigabit switches. With a total output power of 140 W and wide AC input support (90–264 VAC, 47–63 Hz), the DPS-500A is designed to supply full output to the switch and help maintain network availability in the event of an internal power-supply failure. The unit is compact and intended for modular deployment either as a standalone module or installed in a DPS-800 rack chassis.

Advantages

The DPS-500A continuously monitors the switch’s internal power supply and takes over immediately during an interruption, protecting connected devices and minimizing network downtime. It supports hot-swappable installation in the DPS-800 chassis and accepts universal AC mains voltages without configuration changes to the LAN switch. The device is compact, weighs 1.51 kg and comes with the required connection cables for most supported switches.

Suitable for

• Providing power redundancy for D-Link Gigabit and Fast Ethernet switches
• Rack-mount setups when used with DPS-800 chassis
• Environments requiring uninterrupted network availability

How to use

Connect the DPS-500A to any compatible D-Link switch using the supplied cable. If installing in a rack, insert the module into a DPS-800 chassis (up to two modules per chassis) and secure the chassis in a standard 19-inch rack. Power the unit from an AC mains source within the specified range. No changes to the switch configuration are required; the RPS monitors the internal power supply and provides backup automatically when a failure is detected.

Recommendations

Install the DPS-500A in an environment with adequate ventilation and stable AC supply. For rack installations, use the DPS-800 chassis to enable hot-swappable redundancy. Verify compatibility with your specific D-Link switch model and, if required for certain models, order any special cable separately.
