Dual Feed & Static Switch PDUs

A Mission Critical PDM is an extremely flexible power distribution system that can be easily modified to work with any critical power system configuration. Until now, virtually all computer power distribution units featured a single main circuit breaker and one high isolation transformer feeding multiple panelboards for distribution of the protected power to the critical loads. United Power’s Mission Critical Power Distribution Modules allow the critical power system’s redundancy to be extended from the service entrance through to the output distribution circuits feeding the critical loads.

See brochure for more information on MC Power Distribution Modules.

Series MC-1 and MC-2 Systems

United Power’s MC-1 and MC-2 systems offer cost effective internal redundancy and make-before-break transfers by manual operation and optional push-button controls. The make-before-break transfer allows the user to perform system maintenance without downtime. Redundant input breakers and transformers dramatically reduce recovery time in the event of an equipment failure. The MC-1 with its dual input breakers is often used as an economical maintenance bypass. The MC-2 allows 100% of the load to be placed into either side of the PDM for system maintenance without downtime. During normal operation, each transformer carries not more than 50% of the load.

Series MC-3 and MC-4 Systems

United Power’s MC-3 and MC-4 systems feature advanced static transfer switches (STS) complete with on-board diagnostics that monitor each of the two input sources for any abnormal characteristics. In the event of a power problem, STS allows a transfer from the preferred power source to the alternate power source within four milliseconds (less than one-quarter cycle) without any exchanged current. By integrating the ultra-fast STS into the power distribution unit, the flexibility and reliability of the entire critical power system is increased. Other features include dual input circuit breakers and dual isolation transformers.

Model SDX – Series Design

Model SDX is a high performance series design transient voltage surge suppressor for critical applications. The SDX has been designed for service entrance applications as well as distribution systems that provide power to critical equipment. The SDX has continuous current ratings of up to 4000 Amps, voltage ratings up to 600 VAC, 640,000 surge amps per phase (320,000 per mode), and superior noise filtering performance.
SDX incorporates model-specific inductive elements placed between modular hybrid TVSS circuits. The inductive elements reduce the impact of a fast rising transient. This minimizes damaging peak currents, lengthens component life and lowers clamping voltage. The inductive elements also add to the noise attenuation provided by our hybrid circuit, further reducing electrical noise.

A disconnect switch allows for ease of maintenance without having to remove the protected load. SDX uses through-bus technology and internal disconnects to isolate the load bus and eliminate down time for system maintenance. Isolating the load bus in this way eliminates the concerns previously associated with “series” type systems.
