Description
The Server Technology® PRO2 STV-4521V Switched PDU (Primary) delivers advanced power distribution, monitoring, and control for mission-critical data centers. Designed with billing-grade PIPS® (Per Inlet Power Sensing) technology, it measures current, voltage, power, energy, and more to help optimize rack-level energy use.
With network monitoring via HTTP(S), SSH, SNMP, LDAP, RS-232, and more, this unit ensures secure, real-time visibility into your power infrastructure. Its hot-swappable network card and Star Multi-Linking allow up to four circuits to share one IP address, while outlet-level switching provides remote reboot and power management.
Built for reliability, the STV-4521V supports high retention locking outlets, branch circuit protection, and operation up to 60 °C, making it ideal for high-density racks. Color-coded options and flexible mounting enhance deployment in enterprise environments.
