New Hammerhead Converters For Harsh Environment


In order to meet the requirements of achieving high output current under high temperature applications, GE announced the launch of new Hammerhead isolated dc-dc converters. The Hammerhead Series offer an ultra-wide input voltage range from 18 to 75Vdc with Total Efficiency architecture technology that reduces power loss up to 50 per cent. These products are designed for extreme temperature conditions of -40° C to 85° C and are cost-effective modules for medical, military and other industrial applications.

According to the press release, “The QHHD019A0B Hammerhead Series, quarter-brick, low-height power modules are isolated dc-dc converters which provide a single, precisely regulated output voltage over an ultra-wide input voltage range of 18-75Vdc. The QHHD019A0B provides 12Vdc nominal output voltage rated for 19Adc output current. QHHD019A0B is based on open-frame module construction which enables designers to develop cost and space efficient solutions. The module achieves typical full load efficiency greater than 93 per cent at VIN=24Vdc and VIN=48Vdc.” The release further states that the converter exhibits features such as remote on/off, remote sense, output voltage adjustment, overvoltage, overcurrent and over temperature protection.

Referring to the release GE’s QHHD019A0B isolated DC-DC converters are globally available in volume quantities with pricing starting at US$ 31.10 per module.


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 228W
  • Nominal output voltage of 12 volts at 19-amp output currents
  • Robust 2250-volt isolation
  • Typical full-load efficiency greater than 93 per cent at input voltages of 24 volts and 48 volts
