6-Kilowatt Rectifiers Provide Data-Hungry Applications with Industry-Leading Power Conversion Efficiency

GE's Critical Power business introduced its new GP100 line of power rectifiers, providing data- and power-intensive three-phase applications with the industry's first compact, 1U, 6kW 54V AC-to-DC power rectifiers. The new GP100 line includes GE's GP100R compact, module for data center and telecommunications rack or cabinet mounting and its GP100M for embedded data, networking and industrial power supply solutions.

Ideal for high-density data and communications settings, the new GP100 AC-to-DC rectifiers feature a power capacity of 6 kW and take up less than half of the space required to install similar products-enabling two GP100s to be mounted together in 1U of rack space. This combination of power capacity and reduced footprint enables GE to provide an industry-leading power density of 12 kW per 1U, making the GP100 the highest density three-phase power supply available today. The GP100 rectifiers also can be paralleled into packaged systems ranging from 12 kW to 432 kW, providing efficient power to high-density and high-capacity applications such as 48-kW power bays and cabinets. This enables these applications to implement three-phase power supplies instead of being limited to less-efficient, single-phase options due to space requirements.

With an energy conversion efficiency level of up to 96.5 percent, the GP100 line provides benefits of both operational cost savings and improved total cost of ownership. The new rectifier product line also helps eliminate potential single-phase balancing issues as power requirements grow by ensuring that electrical phases grow in equal increments.

The new GP100 rectifiers were developed using FastWorks methodologies, a set of tools and principles that integrate external thinking and discussion into the design process, bringing the products to market faster than previously possible. Using FastWorks, GE was able to take feedback from customers regarding their power needs and their space limitations and directly apply it to the design of its new rectifiers. For example, in many applications, the installation of three-phase power supplies required customers to increase the size of their box or equipment to accommodate the size of the units. In addition, the amount of power capability per bay in the telecommunications industry is reaching a finite limit. With this information, GE was able to design a new rectifier with a smaller footprint and thus, a higher power density-providing customers with the technology they require to address these issues.

The GP100 is the new building block for system architecture and design in DC output products. While other rectifiers in the industry may be limited to installations in traditional system architectures, the GP100 will challenge how and where a rectifier can be used. Offering a very usable form factor and high-density footprint, GE's new rectifiers provide the flexibility needed to meet the power capacity challenges of applications across a wide spectrum of industries.

The GP100R and GP100M add to GE's new GP100 rectifier line of power conversion products. The platform also includes a 1U, high-density product that is specifically engineered for single-phase power supply designs. The rectifier platform also offers expanded communications and diagnostics, such as black box capture capability, field installable firmware upgrades and improved AC measurement accuracy.
