Description

The PWR-3001-DC-RED is a 3000W DC power supply module for the Arista 7280R3 series of data centre switch routers. It is a hot-swappable unit built for facilities running -48 VDC infrastructure, such as telco, central-office and data centre environments that need redundant DC power.

This variant delivers 3000W of output from a -48 to -60 VDC input at 94% efficiency, with a maximum input current of 69A at -48V. Input is terminated with DC lugs for cable up to AWG #3. The red handle and the -RED suffix identify the forward, front-to-rear airflow version, so it suits switches cooled in that direction. It is a 1RU hot-swap module.

It is used in the 7280R3 and 7280R3A family, for example the DCS-7280DR3A-54, which takes the PWR-3001 PSU family in AC or DC. Fan trays must match the airflow direction, so confirm the supported PSU list and airflow for your exact switch model before ordering.

Enquire with XS Network Tech for new or used pricing and availability.
