Reliable power supply of industrial mainboards: DC ATX converter with contact cooling and 6…36V input


The fanless DC ATX converter DC161W from Bicker Elektronik GmbH, Donauwoerth/Germany, is ideally suited for mobile applications in the 12V or 24V on-board network as well as for industrial and medical embedded IPCs. +5Vsb / +3.3V / +5V / +/-12V are available at the ATX output with precise control. The highly efficient DC/DC converter with 93% efficiency is equipped with particularly high-quality components and a robust circuit design – which is reflected in an MTBF of 990,000 hours. The converter is designed for reliable 24/7 continuous operation in the extended temperature range of -20…+70°. With a wide-range input from 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 and convinces in a variety of application fields, such as Industry 4.0 / IIoT, gateways, medical technology, transportation, digital signage, POS/POI, etc.

Flexible cable management

The cable management system of the DC161W allows the flexible use of customer-specific cable harness solutions. On request, Bicker Elektronik can carry out the complete assembly of the cable harness with individual cable lengths and plug connections.

Thermal pad for contact cooling included

For the optimal thermal connection of the power components on the underside of the circuit board, a suitable thermal pad (gap filler pad) is already included in the scope of delivery of the DC161W. Due to the very good thermal management, the warming of the DC161W is reduced to a minimum and thus makes maintenance-free systems without rotating fans possible.

Vehicle ignition functions

The 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 the start and shutdown of the CarPC can be individually configured using extended timing modes and a mainboard on/off connection (Intel® ATX 12V compatible). The selectable autolatch function ensures, for example, that the CarPC is started up and shut down safely, even with a very short ignition plus. The integrated deep discharge protection constantly monitors the voltage of the vehicle battery and automatically switches off the DC161W as soon as the battery voltage falls below a defined voltage value for longer than one minute. In addition, the DC161W has a remote on/off connection for the car amplifier.
