USB Charger for Mobile Phones and Tablets in Railway Applications

With an input voltage range of 8 to 26.4 VDC, the USB charger for mobile phones and tablets in railway applications can be operated on 12 VDC or 24 VDC sources.

For example, up to 4 chargers can be connected in parallel to the intreXis 50 W DC-DC converter IC271. The connected mobile phone is automatically detected and the optimum charging current is set.

Your advantage is that you can charge devices from Samsung, Apple and many other manufacturers with maximum charging current. If the USB charger is damaged by vandalism, it can be easily and inexpensively replaced as a single item.
