GE Energy Delivers Industry-First 300W Eighth Brick Bus Converter

GE Energy (NYSE: GE) is launching a power electronics industry first with the availability of a new eighth brick Barracuda™ series 300W fully regulated digital bus converter. Developed through collaboration with leading technology sector original equipment manufacturers (OEMs), the new DC-DC isolated power modules are the result of a 14-month, $1.1 million technology investment by GE in advanced DC power converter technology and associated software-based digital control. The new Barracuda series of fully regulated digital bus converters help power innovation in OEM new product designs, while reducing risks, accelerating time to market and lowering costs. The Barracuda series is a drop-in replacement for unregulated and semi-regulated bus converters challenged by recent industry-wide intellectual property issues. The standards-based DOSA footprints and analog/digital compatibility with existing circuit board designs shrinks the size, lowers the cost and improves the performance of DC-DC converter modules.

Designed for Intermediate Bus Architectures, the Barracuda eighth brick EBDW (digital) and EBVW (analog) 25 Amp modules offer a wide input voltage range of 36Vdc to 75Vdc with an energy efficiency rating of 95 percent that outperforms competitive offerings. The 58.4 mm x 22.8 mm x 11.3 mm compact form factor reduces circuit board real estate requirements.  A wide operating temperature range of -40°C to +85°C is combined with an industry-standard PMBus™ interface for remote visibility and control. The new Barracuda module is priced to encourage rapid adoption in new and existing computing, networking, data storage and mobile internet infrastructure product designs, powering an array of point of load (POL) converters.

“The Barracuda series gives global OEMs the confidence to leverage the energy efficiency benefits of digital power control, with cost-effective, multi-sourcing options for supply chain efficiency,” said Jeff Schnitzer, president of GE Energy’s Power Electronics business.  “The new software-based digital control technology developed for the Barracuda series will be utilized as part of future GE Energy power electronics solutions to dynamically optimize end-to-end energy efficiency from building to box to board.”

The Barracuda EBDW (digital) series incorporates digital communication, advanced synchronization features, load sharing, differential remote sense and output voltage trim. The Barracuda EBVW (analog) series is compatible with the DOSA standard 5-pin bus converter pin out. Protection features include overtemperature, output overcurrent and overvoltage combined with built-in filtering for both input and output voltage.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…


TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

IDEC Releases New Line of High Efficiency Power Supplies
