GE Critical Power has added the EHHD 120-Watt, HAMMERHEAD™-series isolated dc-dc converters that provide a single, precisely regulated output voltage over an ultra-wide input voltage range of 18- to 75-Vdc. Comprised of three eighth-brick, low-height power modules, the EHHD power modules provide nominal output voltages of 12-, 5- and 3.3-Vdc and are rated for output currents of 10-, 24- and 36-A, respectively.
The module achieves typical full-load efficiency of greater than 90 percent at input voltages of 24Vdc and 48Vdc. Standard features of the HAMMERHEAD-series units include remote on/off, remote sense and output voltage adjustment along with over-voltage, over-current and over-temperature protection. In addition, the EHHD converters feature 2,250-volt isolation, enabling its use in power over Ethernet applications.
