The DC161W converter has 93% efficiency with a n MTBF of 990,000 hours and is built for 24/7 continuous operation in the extended temperature range of -20 to +70°C. With a wide-range input of 6 to 36 VDC, the DC161W ensures the reliable and stable power supply of the connected mainboard even with strong fluctuations in the supply voltage. It is aimed at applications such as Industry 4.0 / IIoT, gateways, medical technology, in-vehicle systems, digital signage and point of sale. The extended operating modes for in-vehicle applications include vehicle ignition functions for intelligent shutdown control with deep discharge protection for vehicle battery. 

To ensure an optimal thermal connection of the power components on the underside of the board to the computer housing, the DC161W comes with a matching heat-conducting pad and an additional mounting hole in the middle of the board. Due to the very good thermal management, the heating of the DC161W is reduced to a minimum, making maintenance-free systems without rotating fans possible. A reverse polarity protection at the input, short-circuit and overvoltage protection at all outputs and an over-temperature protection provide additional operational safety. 

The new DC161W can be operated both in standard power supply mode and in vehicle mode, for example for CarPCs. The ignition-dependent ATX power supply as well as start and shutdown of the supplied CarPC can be individually configured via extended timing modes and a mainboard on/off connection (Intel® ATX 12V compatible). The selectable auto-latch feature ensures, for example, safe startup and shutdown of the CarPC, even with a very short ignition boost. The integrated deep discharge protection constantly monitors the voltage of the vehicle battery and switches off the DC161W automatically as soon as the battery voltage falls below a defined threshold for more than one minute. In addition, the DC161W has a remote on/off connector for the car amplifier to turn it off in time to prevent audible feedback during CarPC system startup. At the outputs (+ 3.3V, + 5V, + 12V, -12V, + 5V-Standby) no base load is required, so that latest mainboards with special energy-saving modes can be safely supplied.

Optional accessories for DC161W include the DC input cable PSZ-1030, the pluggable ATX/P4 harnesses CB-DC100W, CB-DC120W-P4 and PSZ-1041, and the compact EMC filter module PSZ-1040. For connection between DC161W and mainboard the two-pole connection cable PSZ-1020 is available. Bicker Elektronik grants a three-year warranty on the DC161W, as well as a long-term availability of at least 5 years.

As part of the Power+Board program, designers can receive tested and perfectly matching PSU + Mainboard bundles plus comprehensive industrial-grade accessories from a single source.
