Alfatronix's PV12S(-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 PV12S(-A) supports 12A continuous load, with an intermittent load of up to 18A (for a maximum of 2 minutes, followed by 8 minutes rest).
The PV12S(-A) is therefore ideal if you wish to supply our higher power in-vehicle computers, such as the CQ60 series, with a nominal 12V supply in a 24V vehicle. Note that for our other in-vehicle computers we recommend the lower power PV6S(-A), and for in-vehicle routers the PV3S(-A).
The PV12S(-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:
