AC/DC rectifiers provide a power density of 12kW per 1U

Suitable for high-density data and communications settings, the GP100 AC/DC rectifiers feature a power capacity of 6kW 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 a power density of 12kW per 1U, making the GP100 the highest density three-phase power supply available today. The GP100 rectifiers also can be parallelled into packaged systems ranging from 12kW to 432kW, providing efficient power to high-density and high-capacity applications such as 48kW 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.

“Three-phase rectification frees system designers from the burden and complexities of phase balance and offers a simple, swappable solution,” said Karim Wassef, General Manager, Embedded Power, GE’s Critical Power business. “Enabling three phase in 1U combines the best of both worlds without compromise.”

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

“There isn’t a power design engineer out there who isn’t trying to get more power in less space,” said Vito Savino, General Manager, DC power systems, GE’s Critical Power business. “It’s all about reaching new levels of power and density, whether it’s at the board, rack or bay level. With this compact three-phase, 6kW, high-power solution, which takes advantage of the three-phase power already being used at a facility, we’re helping our customers in their drive for larger, yet more efficient, data, communications and computing capacity.”

The 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.
