Description

This 500W (500v2) hot-swappable AC power supply is built for Arista 7050CX3-32S-D switches in the 7050X3 Series. It is used as a replacement or as the second unit in a 1+1 redundant pair in 1RU data centre switches, and suits racks that run front-to-rear airflow.

The unit delivers 500W of output from a 100-240V AC input at 50/60Hz, with a typical input current of 6.3 to 2.3A. It connects through a standard IEC 60320 C14 inlet and has a typical efficiency of 93% at Platinum rating. The front-to-rear airflow variant (-F) suits hot aisle and cold aisle data centre layouts, where cool air is drawn in at the port side.

Use the same airflow direction for both power supplies and the fan modules in the chassis. The rear-to-front equivalent is PWR-501AC-R.

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