10 to 30-W chassis mount DC-DC converters offer space saving benefits
October 07, 2011 // Paul Buckley
CUI Inc has released a new line of 4:1 input DC-DC converters ranging from 10 to 30 W that are housed in a compact chassis mount package. Featuring screw terminal connections, the VYB10W-T, VYB15W-T, VYB20W-T and VYC30W-T Series are designed for applications where the convenience of chassis mounting is required, including transportation equipment, mobile equipment, and telecom base stations.
With a temperature range of -40 to + 85 °C, the converters are ideally suited for most operating environments.
Available in +3.3, +5, +12, or +15 V dc single output models and ±12 or ±15 V dc dual output models, the converters accept input voltages of 9-36 V dc or 18-75 V dc. The wide input range is useful when being driven from a fluctuating device such as a battery which can see both charging and discharging conditions. All outputs are fully regulated to within ±0.5% over all line input conditions and ±1.0% for all load conditions. Additionally, input to output isolation of 1,500 V dc is provided across the range. Dimensions for the VYB10W-T, VYB15W-T, and VYB20W-T Series are 55 x 35 x 19 mm while the VYC30-T Series measures 67.5 x 55 x 19.1 mm.
Single output 15 W, 20 W and 30 W models offer an output trim that allows adjustment within ±10% of nominal output, while all models include remote on/off. Additional features include short circuit protection for the entire series, and over current and over voltage protections for 15 W, 20 W and 30 W models. An optional accessory kit is also available for DIN rail mounting.
The VYB10W-T, VYB15W-T, VYB20W-T and VYC30W-T Series are available through Digi-Key starting at $29.49 for 100 pieces for 10 W models.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
