About D4K-PSU-300W-HV

The D4K-PSU-300W-HV module is a power supply unit or PSU module. This PSU module has been manufactured by Hirschmann and it is designed to supply power to switches and media modules from the Hirschmann DRAGON series of rack mount switches and related products. The D4K-PSU-300W-HV power supply module is sold separately from the DRAGON series switches that it connects to, but it is designed to be easy to install, repair, and replace in the field. Many of the Hirschmann DRAGON rack mount switches can accommodate 2 PSUs like the D4K-PSU-300W-HV power supply module at a time and they can use 1 PSU as the standard power supply and the other as the redundant power supply to minimize the risk of power failures and downtime.


The Hirschmann D4K-PSU-300W-HV power supply module from the DRAGON rack mount switch series is a high-voltage power supply unit with a nominal power rating of 300 Watts, an AC voltage rating of 100 to 240 Volts AC, and a power consumption rating of 6 Watts. It mounts on the host rack mount switch with its convenient plug-in mechanisms. This power supply module uses LED status indicators on the switch chassis for indicating power and software status updates to the users. Although it is a high-voltage PSU, the D4K-PSU-300W-HV module only weighs about 0.85 kilograms and its compact dimensions are 40 x 80 x 250 millimeters. The rated operating temperature range for the D4K-PSU-300W-HV power supply module is from 0 to 60 degrees Celsius and the rated storage temperature range is from -40 to 70 degrees Celsius.
