Bicker Elektronik has offered with the DC161W a compact DC/DC ATX converter with cable management for individual wiring harness configurations. The compact ATX power supply solution for fanless Embedded Box PCs also has an expanded set of operating modes for in-vehicle applications, so-called vehicle ignition functions for intelligent shutdown control with deep discharge protection for vehicle battery.

The power saving DC/DC converter with 93% efficiency is equipped with high-quality components and a robust circuit design, which is reflected in an MTBF of 990,000 hours.

The DC161W 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.

The new DC/DC ATX power supply convinces in a variety of application fields, such as Industry 4.0 / IIoT, gateways, medical technology, in-vehicle systems, digital signage, POS / POI and many more.

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.

In addition to the direct DC power supply, Bicker Elektronik offers a range of high-quality and fanless AC/DC open-frame switching power supplies for AC power supply of the DC161W as well as energy-saving external AC/DC power supplies with industrial and medical approvals.

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.

Available 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. In addition, Bicker Elektronik offers comprehensive value added services, especially for system developers.

These include personal on-site consulting during the design-in process by experienced sales engineers and subsequent project support by the sales, development and service teams of Bicker Elektronik.

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

On request, the specialists from Bicker Elektronik realise customer-specific special solutions and also offer extensive laboratory and measuring services for complete customer systems.
