UK - Powerbox has announced the launch of four new series of extra-wide input voltage range, 8W to 20W board-mounted DC/DC converters for railway and transportation industry.
With a 13:1 input voltage range of 12V to 160V, the MAD33 (8W), MAD32 (10W), MAE35 (15W) and MAF35 (20W) have been developed to provide systems designers with a single part number that is able to power a large range of transportation industry applications (e.g. railway, industrial automation and automotive, remote radio-control), reducing inventory, time to market and documentation.
The MAD-MAE-MAF series are designed to meet railway specifications EN50155, EN50121-3-2, EN61373 and EN45545, but as well ISO7637-2 for 24V vehicles, and EN12895 for industrial trucks and other industrial applications such as robotics. The 8W MAD33 is packaged in an industry standard DIP24 case, and the MAD32, MAE35 and MAF35 are housed in a 2x1 inch case. All four series have a typical efficiency rating of 86%, which considering the extra-wide up to 13:1 input range is an outstanding figure.
“Time to market is very important for systems designers as is simplicity of the sourcing / supply chains in order to reduce downtime in the case of trains maintenance or hardware upgrades. Both are driving forces behind extra-wide input range converters and we see similar demands from other industries such industrial automotive,” said Martin Fredmark, Powerbox’s VP portfolio management.
“Designing 13:1 input range DC/DC converters is very challenging in order to optimize all parameters while keeping the highest possible efficiency levels across the whole input voltage range, and we are proud that our designers achieved this in the new MAD-MAE-MAF series.”
The new series of converters are suitable for low power loads and devices in railway applications such as communication devices, GSM-R phones and their docking stations, routers/Wi-Fi access points, small screens, USB charging sockets (both in-seat and driver’s cabin), sensors, and standby power for larger devices.
