Converters and Power Supplies for the Communications, Automotive & Marine Industries



The widespread use of smartphones and computer tablets has created an increasing need for user accessible, on the move charging systems. The PowerVerter USB Chargers can be easily installed onto any vehicle and allow both drivers and passengers to readily access power to charge any device connected via a USB lead. This type of system has the distinct advantage of largely negating the need for mains electricity on vehicles. The 5Volt DC power is much safer than mains, so installation is quick and simple. Passengers can access the charging facility directly and power their equipment simply through the USB charging lead which is supplied with all such products.
All versions in the range can be connected directly to both 12Vdc and 24Vdc systems without adjustment. The advanced electronic design will also automatically detect if the device is an Apple or Android configuration and alter the charging process accordingly. This ensures that whatever device is connected, be it Apple, Android, iPad, phone or tablet, it will always be charged as fully as time and capacity allow. This avoids the confusion of providing dual outputs which can often appear to be charging when in fact they are doing little more than lighting the LED.


The product is available in three configurations. The PV USB-1 can be installed in a dashboard or fascia display, connected invisibly from behind and retained with the threaded securing ring provided. Where there is limited rear access, a front retaining plate is supplied as an alternative. In each case, an attractive professional finish is achieved. PV USB-2 provides the same performance but is designed to be installed out of the way with other wiring, while USB-3 offers a slim-line socket with a 30cm cable. This allows the user interface to be installed in PV USB-1 positions where there is limited depth available such as seat backs or armrests, while the actual charger can be located out of the way along with other wiring. Both PV USB-1 and USB-3 have a subtle blue LED to highlight their location on the vehicle and include an optional dust cover for when not in use.


The PowerVerter USB Chargers are designed to BS EN50498 and ISO 7637-2 and are both CE and E marked for commercial, on board vehicle installations. The casings and mounting components are manufactured in high quality impact resistant V-0 rated polycarbonate and the electronic assembly is entirely by computer controlled SMT for maximum reliability.
