The specs state that the DC input should be able to support loads of 2A, but what about an Asset Tracker installation that also uses a fully charged LiPo? Won’t the current peaks be drawn of the LiPo in that case?
The reason I am asking is that I need to get my input voltage from a 40.8V source, and that the pre-built step down converters I find that support these kinds of voltages ( +40V) only output 600mA.
The ones that can do more amps are only rated to 40V.
I’d rather not build a DC converter circuit myself as this system should be used in more than 100 devices.
Yes, the Li-Po will provide the power for the current peaks.
But you can supply 12V to the Asset Tracker, which is helpful if you don’t want to use the Li-Po( possibility of high temps, etc).
I’m sure there are much better options available, but here’s a sample for 40V to 12V
Reminder: Amps decrease as supply voltage increases.
I’m sure someone here has a recommendation for a quality buck converter for a “clean” power supply @12V.
I currently have one from Velleman, but as this example, it’s rated for 40V. max.
I am measuring 40.8V input when the LiPo pack that’s powering it is at 100% charge, so I don’t know if it is safe to use in the long term.
