DAR-R4P Express Power Card for Management System


product_description

The DAR-R4P is a rack-type power card for units such as the DAR-RACK 19" Rack for Management System where it provides 48/60 Vdc local power to the unit. Each card has 4 separate power interfaces towards the remote areas. The purpose of the device is to provide remote power to areas that lack local power source.

Possible applications:

  • Powering and supervising DAR units

  • Powering Data-PowerBoost including the xDSL data link
