228W DC-DC with Ultra-Wide Input Range of 18-75 Volts

February 28, 2015 By admin Comments are Off , , , ,

GE’s Critical Power business has expanded its Hammerhead series of dc-dc modules with its new 228-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- to 75-Vdc. 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. They have a nominal 12-V output voltage that is rated for 19A. The new modules achieve typical full-load efficiencies of greater than 93% at input voltages of 24Vdc and 48Vdc.

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.

“The flexible QHHD plays the dual role of wide-input industrial bus converter as well as a consolidating bus solution for low- and high-input voltage telecom applications, observed Karim Wassef, general manager, embedded power, GE’s Critical Power business. “On the industrial side, the 18- to 75-Volt input allows for large excursions without interrupting power to the downstream converters. For telecom applications, both 24-Volt and 48-Volt dc application can be satisfied with a single solution, simplifying supply chain and consolidating spend,” Wassef concluded.

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.

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 12V of power. The modules also feature 2,250V isolation, making them suited 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.
