AEG introduces DC power supply for industrial applications

AEG's DC system

Uninterruptible power supply provider AEG Power Solutions (AEG) has launched a modular DC process power supply system for industrial applications with high power demands.

AEG ‘s Thyrobox DC-3 power supply system is designed on the base of the B12-IGBT-chopper technology and has a modular structure. The smallest Thyrobox DC-3 has an output power of 1,500A and can be modularly expanded to 30,000A.

According to Germany’s AEG, load voltages from 20V up to 500V can be achieved with the new product. The system also allows a configuration with redundant modules. The Thyrobox DC-3 operates so that more power modules can be upgraded by parallel connection to an existing DC system.

Due to a high load current and load voltage with a small output as well as an optimised supply network load over the control range, the DC system has a high power factor, claimed the company.

The DC system can be connected to a low or medium voltage grid. Separate power transformer and secondary side wiring with bus bars or cables are optional.

The product was developed at the company's competence centre in Warstein, Germany, where it will also be produced.

Emerson reveals 120kW DC power system

Emerson NetSure

Emerson Network Power has expanded its 400V DC power platform with a 120kW power system for critical power applications.

The NetSure 9500 is designed for telecom, data centre and commercial building applications. The design shall enable deployment in various configurations, allowing scalable growth to avoid stranded capacity. An integrated distribution module faciliates extended load distribution positions.

The system provides a battery cabinet containing one string of valve-regulated lead-acid (VRLA) batteries. It uses the same architecture like the 30kW NetSure system.

“The NetSure 9500 provides an alternative to traditional -48V DC power systems in the telecom space and to AC UPS systems in data centers. It also is a natural fit for commercial buildings, where DC microgrids that integrate distributed energy sources are increasingly common”, said Thomas Bennett, vice president of product management for the energy systems business of Emerson. Moving from -48V to 400V DC, reduces the costs of telecom providers by up to 80%, stated the company.

The first deployment of the product is by US-based Steel ORCA, which provides AC and DC solutions. “We recognise that the industry is looking for ways to maintain or improve reliability while maintaining or reducing cost,” said Dennis Cronin, chief operating officer of Steel ORCA.
