Description
The Server Technology® PRO2 STV-4521Y Switched PDU is engineered for data centers that demand precision, reliability, and intelligent power management. Designed with PIPS® (Per Inlet Power Sensing) technology, it delivers billing-grade measurement of current, voltage, power, and energy, helping IT teams optimize capacity and prevent overloads.
With network monitoring, hot-swap network cards, and star multi-linking, the STV-4521Y provides maximum flexibility and resiliency. This PDU supports outlet-level control, enabling rebooting of locked servers or powering down unused outlets. Built for high-density racks, it features 48 IEC C13 outlets, branch circuit protection, and a durable design rated for safe operation in demanding 60°C environments.
Whether you’re scaling operations or protecting mission-critical systems, the PRO2 STV-4521Y ensures accurate monitoring, reliable connectivity, and simplified management through SNMP, HTTP/S, SSH, Telnet, and more.
