96% Efficient Rectifiers for High-Power Applications

January 22, 2019 by Scott McMahan

Eltek, a Delta Group Company, announced the new DPR6000B rectifier product line that uses the company's High Efficiency (HE) technology to provide 96 percent efficiency power conversion for high-power applications. The company designed the rectifiers for Eltek EcoTower and Scalable DC Power Systems

The DPR6000B rectifiers are three-phase, 125A, 48V rectifiers that can provide up to 6kW output power. Two models are available: the DPR 6000B-48 ID:A1 for 480V input applications and the DPR6000B-48 ID:B1 for 208V input applications. The HE technology in the DPR6000B rectifiers reduces waste heat from the power conversion resulting in a high power-density module. The module also boasts dramatic, ongoing cost and energy savings.

The DPR6000B rectifiers upgrade the company's legacy PowerPack rectifier family. Eltek is also offering the PowerPack 11KW Retrofit Kit that lets two DPR6000B rectifiers occupy the same 19"-rack form factor as a PowerPack rectifier.

"The applications served by this new rectifier family need growing amounts of power and will reap a significant operating expense benefit from upgrading to HE technology," said Roel Cortez, Vice President of Sales & Marketing at Eltek. "The addition of the DPR6000B family will mean customers can continue to count on the Scalable System and EcoTower to deliver reliable and efficient power conversion and distribution."


The Eltek EcoTower DC Power System measures 24" Width x 84" in Height x 24.8" in Length and is a single-cabinet solution for medium- and large-power applications.

The EcoTower has a front-access design and features a maximum output of 2400A. The system can be fitted with as many as four different DC distribution panels per cabinet and can support up to eight battery connections.

In addition to DPR6000B rectifiers, the EcoTower also supports Flatpack2 HE 48V rectifiers for up to 2400A of output power. The system is managed by the Smartpack2 controller.

Scalable DC Power System

The Eltek Scalable dc power system (pictured above) is comprised of rectifier bays and optional distribution bays. A rectifier bay can accommodate up to 30 DPR6000B rectifiers for a total output of up to 3,000A. Up to four rectifier bay cabinets can be cabled together for very high-power applications. At scale out, the system can support up to 500,000 Watts.

Distribution bays support flexible distribution options including bulk buses rated at 3000A, 6000A, and 10000A or up to 48 configurable distribution positions. Rectifier and distribution bays can be connected through an Eltek-designed internal bus that works like a system bus, or a traditional overhead-bus structure. Eltek's Smartpack2 controller controls an entire system, including battery and/or gen-set back up.

The DPR6000B rectifiers are available now.
