STI Switched PDU 22.0kW, 230/400V 3-Phase Wye, 32A, 48 x C13 outlets

The Server Technology® STV-4303K (Master) Switched PDU provides control of outlet power and local LED input current monitoring, allowing IT personnel to determine safe levels of loading on a per-phase basis while installing equipment into the rack/cabinet. The integral PIPS® (Per Inlet Power Sensing) technology provides accurate measurement of current (billing-grade), voltage, active power, apparent power, power factor, crest factor, and accumulated energy at the input. These power data points, along with temperature and humidity measurements (provided via optional probes), are accessible through the built-in Web and CLI interfaces as well as through SNMP.

Server Tech STV-4303K Switched PDU Features:

  • Network Monitoring - Gain access to valuable data through connections including HTTP(S), SSH, Telnet, SNMP, (S)FTP, SMTP, Syslog, LDAP(S), RS-232 serial, and more
  • Temperature/Humidity Monitoring - Master and Link units each support two external 10' (3m) T/H probes (sold seperatly). Receive SNMP-based alerts and email notifications.
  • Auto-Flip Current Display - Easy-to-read LEDs display current per phase to help prevent overloads and simplify three-phase load balancing in high-density cabinets.
  • Per-Inlet Power Sensing - Meets ANSI C12.1 for billing-grade accuracy of Current per phase. PIPS includes voltage, active power, apparent power, power factor, and energy.
  • Branch Circuit Protection - This PDU meets the UL and IEC 60950-1 requirement for branch circuit protection through use of UL489 rated magnetic-hydraulic circuit breakers or UL248 fuses.
  • Outlet Control - On Switched rack PDUs, cycle power to individual outlets or groups of outlets to reboot servers. Or, power off unused receptacles.
  • High Retention Locking Outlets - Receptacles have high retention and are compatible with P-Lock type power cords.
  • Flexible Mounting - Includes standard button mounts along with provisions for custom mounting brackets (contact Server Technology for details).
  • Color Identification - Choose from six colors to designate circuits for rack PDUs in the data center. Color options include Blue, Red, Green, White, Yellow, and Black. (To order colors other than black or for more inforamtion, please call your Server Racks Online representativce at 1-866-722-5776.
