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.

High-Density Outlet Technology

The highest outlet density available in a network connected PDU. Meets IEC C13 and C19 specifications, plus high native retention and UL94V-0 flame rating.

Input Current Monitoring

Easy-to-read LEDs display current per phase to help prevent overloads & simplify 3-phase load balancing in high density cabinets.

Alternating-Phase Outlets

3-phase power is wired in an alternating fashion per outlet for simplified load balancing, reduced cord lengths, and better airflow.

Temperature/Humidity Monitoring

Master and Link (select products) units each support two external 10' (3m) T/H probes. Receive SNMP-based alerts and email notifications.

Branch Current Monitoring

PRO2 monitors current at each breaker branch and provides SNMP-based alerts and emails on high usage that risks a tripped circuit.

Linkable Expansion

Connect an Expansion PDU to a Master PDU for power monitoring of separate power circuits from a single IP address.

High Temperature Rating

This product has been tested and approved for safe and reliable operation in 60°C (140°F) data center environments.

Star Multi-Linking

PRO2 provides the ability to link up to four power circuits using one IP address. Primary link provides backup power to network card.

Hot-Swap Network Card

Network access is ensured when power is lost to the Master unit with backup power provided by the primary link unit.

IP Access, Security & Communications

Web, SSH, Telnet, SNMPv2c & v3, RS-232 serial, 10/100 Base T-Ethernet, LDAP(S), TACACS+, RADIUS, DHCP, & SMTP/email.

Power Pivot™

The 90 degree rotatable power cord allows for standardized deployment at any facility no matter where power must be routed.

Outlet Control

On Switched PDUs, cycle power to individual outlets or groups of outlets to reboot servers. Or, power off unused receptacles.

ST Eye Bluetooth Ready

The best PDU LCD is the one in your hand. Attach the ST Eye™ Bluetooth module to this PDU for access to power data and system settings.

POPS® (Per Outlet Power Sensing)

Monitor Current Load (A), Voltage (V), Power (W), Apparent Power (VA), Crest Factor, Power Factor, and Energy per outlet.

Flexible Mounting

This PDU includes standard button mounts along with provisions for custom mounting brackets (contact Server Technology for details).

PIPS® (Per Inlet Power Sensing)

Monitor Current Load (A), Voltage (V), Power (W), Apparent Power (VA), Crest Factor, Power Factor, & Energy per inlet.

POPS® (Per Outlet Power Sensing)

Monitor Current Load (A), Voltage (V), Power (W), Apparent Power (VA), Crest Factor, Power Factor, and Energy per outlet.

Cable Retention

Reduces accidental disconnects by ensuring that power cords are solidly connected to their respective devices.

Startup Stick™

The quick and easy solution to CDU configuration when DHCP is not available.

Color Coded PDUs

Select from six colors to designate PDU circuits in the data center — black, white, red, green, blue, and yellow.

PDU Features & Solutions

Tools and Features

High Density Outlet Technology (HDOT) : Your Density Solution

Short on real estate, high on rack components? Choose High Density Outlet Technology. HDOT has the most outlets in a 42U intelligent Rack PDU with industry standard C13 and C19 outlets. Comes with high native cord retention and color-coded alternating-phase outputs for easy cabling and operation to 65C (149F) ambient.

Alternating Phase Technology : Your Load Balancing Solution

Choose Alternating Phase. Alternating phase outlets alternate the phased power on a per-outlet basis instead of a per-branch basis. This allows for shorter cords, quicker installation and easier load balancing for 3-phase rackmount PDUs. Shorter cords mean less mass, making them less likely to come unplugged during transport of the assembled rack.

PRO2™ PDU : Your Uptime Solution

The next evolution in PDU design; with a shallower form-factor, faster processing, and more memory. Your Uptime solution

Sentry Power Manager (SPM) : Your Capacity Solution

Award winning, most comprehensive and affordable rack-level solution for measurement and reporting. Your Capacity Planning solution.
