FAQs
Mounting requires the VX IT enclosure frame or mounting angles of at least 800 mm. The PDU supports vertical zero-U installation in compatible VX IT frames, enabling tool-free integration and space optimization. Ensure the zero-U space is available within the IT rack and that the enclosure provides adequate airflow for the 7.4 kW load. Connection is via standard CEE input with a 3 m cord for flexible routing.
Each output slot includes energy measurement and monitoring capability, enabling per-socket data collection. The PDU aggregates power usage at the 4x C13 and 2x C19 outlets, aiding load balancing and capacity planning. Data is accessible through the web interface and network protocol stack (HTTP, HTTPS, SSH, Telnet, NTP) for integration with DCIM and asset management systems.
Yes. The PDU operates at 230 V AC with a rated current of up to 32 A and a total power capacity of 7.4 kW. It provides 4x C13 and 2x C19 output sockets, fed by a CEE input. The 3 m connection cable supports flexible routing in dense data center racks and telecom rooms, ensuring compatibility with standard IT equipment and power distribution schemes.
The PDU meets EMC Directive 2014/30/EU and EN 62368-1 standards, indicating compliance with electromagnetic compatibility and modern safety requirements for information technology equipment.
