Alfatronix's PV3S(-A) is a rugged and reliable voltage dropper that allows equipment designed for 12V operation to be used in vehicles with a 24V electrical system (e.g. trucks and buses). The PV3S(-A) supports 3A continuous load, with an intermittent load of up to 6A (for a maximum of 2 minutes, followed by 8 minutes rest).
The PV3S(-A) is therefore ideal if you wish to supply any of our routers with a nominal 12V supply in a 24V vehicle. Note that for our in-vehicle computers we recommend the higher-power PV6S(-A) or PV12S(-A) models.
The PV3S(-A) fits onto a supplied "Click 'n' Fit" mounting clip which is fixed in three points, allowing it to be mounted on uneven surfaces. A green LED indicates that there is a power output from the converter.
The product is available in two variants as follows:
