Overview
The Server Technology PRO2 Smart PDU (Model STV-3507M) is a high-density, switched rack power distribution unit designed for demanding data center environments. Featuring local LED input current monitoring and billing-grade accurate PIPS® power measurement technology, it gives IT personnel precise visibility into per-phase loading during equipment installation and ongoing operation. The PRO2 Master unit can be linked to up to three PRO2 Link PDUs using a single IP address, eliminating daisy-chain risks while extending network access to redundant power feeds.
Key Features
- Network monitoring via HTTP(S), SSH, Telnet, SNMP, (S)FTP, SMTP, Syslog, LDAP(S), RS-232 serial, and more
- Hot-swap network card ensures network access is maintained even when power is lost to the Master unit
- Star Multi-Linking supports up to four power circuits on one IP address; primary link provides backup power to network card
- Temperature/humidity monitoring via two external 10 ft. (3 m) T/H probes per unit; SNMP alerts and email notifications
- Auto-flip LED current display per phase prevents overloads and simplifies three-phase load balancing in high-density cabinets
- PIPS® Per-Inlet Power Sensing meets ANSI C12.1 billing-grade accuracy — measures current, voltage, active power, apparent power, power factor, crest factor, and energy
- Branch circuit protection via UL 489-rated magnetic-hydraulic circuit breakers (2-pole, 20A trip, 5 kAIC interrupt rating)
- High retention locking outlets compatible with P-Lock type power cords
- Power Pivot™ 90-degree rotatable power cord for flexible deployment
- Rated for operation up to 60°C — ideal for high-temperature data center environments
- Flexible mounting: includes button mounts; provisions for custom brackets available
