Redundant Power Supply DPS-500A
DPS-500A
Keeps your switch online in case of power supply failure.
- Can be installed as standalone module, or in 19-inch rack mountable chassis
- Solid metal housing
- LED status indicators
- 90 to 264 Volts, 47 to 63Hz AC input range
Redundant Power Backup
Each DPS Link is equipped with an integrated detection circuit that continuously monitors the internal power of the switch. If a power failure occurs, the redundant power supply is immediately turned on so that the LAN switches and connected devices can continue to provide services.
This results in a more reliable network infrastructure and protects the network from being dropped due to failure of a single network device power supply.
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.
Modular Redundant Power Supplies
The DPS-500A is a modular redundant power supply that can be installed as an independent power supply or placed in a DPS-800 Rack-mounted chassis. The chassis is designed to be mounted on a standard 19-inch gear rack. Several pieces of power can be placed inside the chassis, from which they can be connected to a switch mounted on the same rack.
Rack Mount Chassis
The DPS-800 chassis can hold up to two DPS-200A modules to the equipment rack. Using the chassis, users can save space while allowing clean wiring. All redundant power supply units installed in the chassis are connected directly to the power source, and are hot-swappable.
Redundant Power Protection
- – Connect to various Gigabit D-Link switches
- – Provide backup power for internal power supply that is on the switch
- – Overcurrent protection
- – LED status indicator
Flexible Usage Options
- – Can be installed as a stand-alone redundant power supply or be installed on a 19-inch multi-slot chassis
- – Hot swappable when installed in the chassis
- – Solid metal housing case
