GE Adds to Extensive Line of Hammerhead Power Converters with Highly Efficient 228-Watt DC-DC Modules

February 18, 2015
  • Features 228-Watt Design with Ultra-Wide Input Voltage Range of 18-75 Volts
  • Space-Efficient, Quarter-Brick Footprint Enables Efficiencies up to 93 Percent 
DALLAS — Feb. 18, 2015 — GE’s Critical Power business (NYSE: GE) has expanded its Hammerhead series of DC-DC modules with its new 228-watt (W) quarter-brick QHHD019A0B isolated DC-DC converters. The low-height modules provide a single, precisely regulated output voltage over an ultra-wide input voltage range of 18-75 volts DC. The new DC-DC converters exhibit GE’s vast heritage of reliability and quality while integrating the latest in technology, component and process standardization. 
These cost-effective and energy- and space-efficient DC-DC converters enable input power flexibility for board designers while providing a common building block that can support multiple sockets. In terms of output voltage, GE’s new Hammerhead converters provide a nominal 12-volt output voltage that is rated for 19 amps output current. The new modules achieve typical full-load efficiencies of greater than 93 percent at input voltages of 24 volts and 48 volts. 
Standard features of GE’s QHHD019A0B DC-DC converters include remote on/off, remote sense, output-voltage adjustment and over-voltage, over-current and over-temperature protection. In addition, an optional heat plate is available, which allows for an external, standard, quarter-brick heat sink attachment—enabling designers to achieve higher output currents in high-temperature applications.
With the addition of the new 228-W QHHD DC-DC converters to its extensive family of Hammerhead products—which include EHHD, KHHD and SHHD modules—GE is able to provide board designers with a wide range of offerings—from 15-W in a 1-by-1-inch module to 228-W in a DOSA-standard, quarter brick unit. This versatility allows GE to provide board designers with the technology they need to meet their unique design challenges.   
Key Features and Benefits of the GE’s QHHD019A0B Isolated DC-DC Converters: 
  • Ultra-wide input voltage range of 18-75 volts.
  • High power density at 228-W.
  • Nominal output voltage of 12 volts at 19-amp output currents.
  • Robust 2,250-volt isolation.
  • Typical full-load efficiencies of greater than 93 percent at input voltages of 24 volts and 48 volts.
GE’s QHHD019A0B DC-DC converters can be used as a traditional DC-DC module, powering devices such as hard drives, fans and other applications requiring 12 volts of power. The modules also feature 2,250-volt isolation, making them ideal for use in power over Ethernet (PoE) applications. Other key applications for GE’s new Hammerhead-series DC-DC converters include hybrid power architectures, wireless networks, enterprise networks (including PoE) and industrial equipment.
GE will be showcasing its new QHHD019A0B DC-DC converters at embedded world 2015 (booth #5-120), which is taking place Feb. 24-26 in Nuremberg, Germany.
Availability and Pricing:
GE’s QHHD019A0B isolated DC-DC converters are now available in volume quantities. Pricing begins at $31.10 per module at original equipment manufacturer production volumes. For more information, please call +1 888 546 3243.
