Alfatronix Powerverter PRO USB Charger

The widespread use of smartphones and computer tablets has created an increasing need for user access, 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 5 Volt DC power is much safer than the 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 12 Vdc and 24 Vdc 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.

The Range

The PowerVerter USB range has been completely re-designed for 2016 to include a standard design that can be used in regular as well as slim-line installations. Aesthetically the design has been improved with a dark grey body and contrasting light grey ring as well as an attractive and more obvious LED indicator. This helps to draw attention to the unit and encourages use. Part numbers are PVPro-S for a single output and PVPro-D for a double output. The front fitting system has also been improved with a round bezel with a tamperproof covering ring to hide the screws, yet still, allow the unit to be replaced quickly and easily should this be required. Part numbers are PVPro-SFf (single output) and PVPro-DFf (double output). Electronically, the design now includes automatic short circuit detection, so in the event of tampering or compromise, the unit will automatically shut down, then re-start again once the fault has been removed. A charger only version is also available for permanent, behind-the-scenes installations without customer interface. The part number is PV-USB2. The range is completed with our ‘Pod’. This is ideal for retrofit installations and is designed to fit underneath the seat in front. This system can also be bought as a complete assembly including; a PVPro USB charger, pod, and 1.2 m of fused cable. Please order part numbers; PVPro-S-Assy (single) and PVPro-D-Assy (double).

Commercial Installations

Like all products, the USB chargers are manufactured using rugged components to provide years of service in demanding commercial environments. Due to the limitations of public use, the guarantee on these products is limited to three years. The PowerVerter USB chargers offer an advanced design that effectively counteracts the voltage drop common when output currents vary as different devices charge at different rates. This avoids the common problem of the phone or tablet indicating it is charging when in fact very little current is being supplied. They also have an exceptionally low quiescent current of less than 2 mA meaning that multiple devices can safely be installed throughout buses and coaches without materially discharging the battery. They have been designed to meet the rigorous standards required for onboard commercial vehicle applications including BS EN50498 and ISO 7637-2 and are both CE and E marked. The casings are made from V0 rated (self-extinguishing) high impact polycarbonate and the electronic assembly is predominantly by computer-controlled SMT for maximum reliability. All versions have a subtle blue LED light to highlight their location on the vehicle.
