3 Phase PDUs (Power Distribution Units)


High-density computing with increased server implementation, greater equipment densities, increased power demands, cost reduction initiatives, green directives, and redundancy are driving the demand for 3 Phase power in the data center equipment cabinet.

The principles of 3-Phase power are not always well understood by the installer, whose only task is to power up the equipment being installed in the computer rack. Load balancing (matching current draw on each phase) is critical in these applications for multiple reasons:

  • If the three phases are not balanced, heat is generated resulting in higher cooling costs.
  • Unbalanced loads lead to inefficiency and higher power bills.
  • High loads on a single phase means greater chance of tripping either a PDU or upstream breaker, and losing power at the rack.

What about those end-users in high-density environments?  For them, it’s not just the sheer number of devices in the rack, it’s also about pushing the volts-and-amps envelope in terms of power.  A three-phase approach is essential for handling such loads. To consider a single-phase PDU versus a three-phase PDU in this scenario is not even a fair fight.  Servertech’s  Alt-Phase PDUs offer a low-maintenance approach for those with high-flying power needs.

Overview

It has been obvious for some time that the power distribution system within the data center is the key opportunity to focus upon in order to actively manage the rising costs of power and more specifically, identify problems and waste in real-time. With future-thinking organizations sharing knowledge between Facilities and IT, the push for more intelligence within this rack-based power infrastructure has become urgent with higher rack power densities. In fact, proactive power management at all stages in the distribution chain within enterprise data centers has become the requirement to feed efficiency studies and optimization efforts.

Key Features of PRO2

The latest innovation from Server Technology, the PRO2 platform, continues STI's more than 30 year tradition of customer driven power solutions development. PRO2 features a flexible hardware platform with more outlets, a faster processor, improved firmware and increased security and redundancy. With PRO2 you can maintain high availability to your data, stay informed of rising loads and be proactive on your power supply management.

Server Cabinet Power Distribution

The goal of our product line and the design of our manufacturing process is to allow our customers the ability to find exactly the right set of power distribution features for their application: from horizontal to vertical, 120V to 415V, low density to high, and from managed/intelligent to not.


Intelligent Power Distribution

Intelligent PDUs combine power distribution, power control, and data collection within a single unit. They supply more power to more devices while providing key information through PDU networking.


Flexible Power Distribution

Server Technology's HDOT Cx PDU, featuring the revolutionary Cx outlet, accommodates both C14 and C20 plugs, reducing the complexity of the PDU selection process and limits the need to purchase a new set of PDUs when equipment changes, resulting in lowering end costs.
