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.

See brochure for more information on Static Transfer Switch.

The service entrance is the first location within your facility where you must prevent high-voltage transients from entering your operation. It is also that point in your electrical system where the most severe transients usually occur. Events such as lightning, utility grid switching, and other high-energy random transient events can cause severe damage to the environment within your facility and interrupt the critical processes of your business.

Model SPD – Surge Protective Device

Throughout the past five years, the transient voltage surge suppression (TVSS) industry has grown from a “niche” market consisting of a few small manufacturers, to one of the fastest-growing segments among all power protection products. Today, United Power is raising the technological bar with its advanced hybrid transient suppression technology. Model SPD, our latest design of high-performance TVSS systems, was specifically designed for hard wired Service Entrance and Distribution Panelboard applications.

Model SPD is the latest evolution of United Power’s quality line of TVSS products. The systems are small, lightweight and feature from 80 kA to 320 kA of surge current suppression per each mode of protection. Model SPD has the surge handling capability necessary to protect your facility’s sensitive electronic loads from the catastrophic effects of high-energy transients. Since SPD is a parallel-connected device, it is perfect for either new construction or retrofit applications.

The professional engineering community has identified transients as the most paralyzing problem within many facilities. Engineers have accepted TVSS as an integral part of any overall power protection strategy.

United Power invests heavily in its research and product development efforts to ensure we continue to be the technological leader in the TVSS industry. The result of that commitment of resources is evidenced in Model SPD.

Model EDP – Electronic Distribution Panelboard

United Power has taken its expertise in service entrance TVSS and integrated our high performance-oriented hybrid transient suppression technology into the distribution panelboard. This combination provides the user excellent protection against high-energy transients for all branch circuits thereby eliminating the need for individual load protectors.

We position our TVSS products into the panelboard to reduce “lead length” for superior transient suppression performance. UL, in its Second Edition listing process, tested this product line and assigned a 330V clamping voltage rating on our popular 120/208 VAC system. There is no product on the market today that provides lower (better) UL clamping voltage characteristics.

Model EDP systems are manufactured in combination with all major manufacturers of panelboards including Square D, General Electric, and others. Systems are available in main breaker or main lug only configurations from 100-400 amperes in all popular voltages. Model EDP systems feature 30, 42, or 84 poles to provide the proper distribution capacity for your site.

Provide a blanket of transient protection for your entire facility by positioning United Power TVSS systems at the service entrance and at each critical distribution location.

See brochure for more information.

Model CPX – Compact Parallel TVSS Systems

Model CPX is designed for applications at the lighting panel or at other sub-distribution or critical load sites within your facility. It is the perfect product for adding additional transient surge protection to back-up the service entrance TVSS system, protecting from transients that are internally generated.
Model CPX is rated for the Category C2/B3 environment and is UL 1449 Second Edition Listed. These systems provide an economical solution for providing TVSS protection in the expanding retrofit TVSS market, or any number of other applications. CPX systems are available in all popular single-phase, split-phase and three phase voltages, including delta configurations.

Model CPX systems utilize the same industry-proven United Power “Clear Choice” hybrid technology consisting of silicon avalanche diodes for less than one nanosecond response time, metal oxide varistors and noise filtering capacitors found in other United Power TVSS products. The hybrid circuitry provides bi-directional protection and is available in surge current ratings from 13,000 surge amps per mode of protection to 40,000 surge amps of protection.

See brochure for more information.

Retrofit Model CPX Onto Existing Lighting Panels

One of the most popular applications for Model CPX TVSS is to retrofit the system onto an existing lighting panel. The system may be field installed using a chase (close) fitting or with a United Power flexible interconnecting flexible cable. Simply position the Model CPX adjacent to the branch circuit breaker that will serve as its disconnect device. Model CPX is an ideal means of protecting all of the critical loads on the panelboard with a single, performance-oriented, IEEE C62.41 Category C rated TVSS device.

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.
