The new ATX DC/DC converter DC160W is a highly efficient power supply solution for fanless Embedded Box PCs. In addition to industrial and medical applications, the motor vehicle ignition feature allows the use of the DC160W in motor vehicle applications. Besides the high efficiency up to 93 %, the DC160W is characterized by an ultra wide input range. This feature ensures the reliable and stable power supply of the connected mainboard, even under extreme voltage fluctuations or dips (engine start). The power components installed on the PCB bottom side, as well as an additional mounting hole in the PCB center ensure the optimal thermal connection to the housing by using a heat transfer pad (included in delivery). Due to the very good heat management, the heating of the DC160W is reduced to a minimum. This allows maintenance-free systems without any rotating fans. The DC160W can be operated both in standard PSU mode, as well as in motor vehicle mode for CarPCs. The ignition dependent power supply and start/shutdown of the CarPC can be individually configured via numerous timing modes and a mainboard On/Off-connection.
