POWERVERTER RAIL USB CHARGERS

12/24VDC USB TYPE A & C CHARGER IP65 PROTECTED

A & C PORT USB CHARGING FOR 12V AND 24VDC APPLICATIONS CERTIFIED TO EN 45545-2 (EN 50121-3-2) AND EN61373 (ROLLING STOCK)

The widespread use of smartphones and computer tablets has created an increasing need for user accessible, on the move charging systems. The PowerVerter PR65R Railway Range is specifically designed to meet all requirements for rolling stock applications. These units can easily be installed into seat backs (space permitting), under the seat, directly into carriage walls, or tabletops using the suitable mounting pods available.

These chargers are available in both standard (secured from the rear with a nut) or front fitting, secured by three screws, covered with a discreet cover ring. Ingress protection is to IP65 (not connectors).

Installations can be carried out two ways:
For systems already galvanically isolated, the PR65R can be connected directly to the electrical system (either 12V or 24V). These units have been approved to EN 50155.

If the system specification requires galvanic isolation, then the PR65R range units can be used in conjunction with the Alfatronix DC-DC Railway isolated converters such as PRi24-12 072, PRi72-12 144 or PRi110-12 288. These units have also been tested as a system to EN 50155. We recommend this option.

Please consult the PowerVerter Railway DC-DC Voltage Converters leaflet for more information and the full range of products available.
Alfatronix products have been tested to Rail Fire EN45545-2.

THE RANGE

All units are installed through a 30mm hole. Standard format units are retained by a rear nut while the front fit versions include a bezel with tamperproof cover ring. Input power is by way of two 6.3mm push-on flat fit automotive terminals.
Electronically the designs include reverse polarity protection and the output withstands short circuit current and will return back to full operation when the short is removed.

SAFETY

A requirement of the USB standard is that the metal cage around the USB plugs and sockets is connected to ground (zero volts). If a USB charger is to be used in an application with a positive ground, i.e. battery/supply positive terminal is connected to the vehicle chassis, then there is a risk that the exposed metal cage of any USB cable could come in contact with the positive connected chassis, causing uncontrolled heating of the USB cable and USB charger and potentially creating a hazard.
In positive ground applications, the use of an isolated Alfatronix Converter is required to be installed between the positive ground supply and the input of the USB charger. Please refer to the PRi DC-DC datasheet.

WARRANTY

The PR65R range of chargers are manufactured using rugged components to provide years of service in demanding commercial environments and are covered by a three year return to base guarantee.
