Are the LtAP (and most 12-57v MikroTik devices in general) safe to have power shut off and turned on frequently and abruptly? Like you’d get in a vehicle-mounted device, wired to start/stop when the vehicle is started/stopped?
In a professional, industry grade install, you have a small battery for buffering, to shut down gracefully in case of power loss.
When using in a vehicle, this also will take care of power fluctuations, especially during start up of the engine.
I have a LtAP but for my house as you can see on my signature. It is protected by an UPS, but anyway sometimes it gets down when I have no light on my house. But, until now, no problems with my LtAP.
Now, I know that LtAP was designed for vehicular applications.
Regards.
I suppose i understand that, but what if the vehicle doesn’t get driven for extended periods of time? At 5 watts continuous, a 30ah battery would be completely drained in a few days.
" … shut down gracefully …" means something like “shutdown” or “halt” to the device. And then, to switch off power to the device, like pulling the plug.
As I read, MTs should withstand abrupt power cut, but I am coming from industrial environments with high reliability requirements, not to take a risk.
Especially, in case of a fleet of devices, operated remotely, or in harsh environments.
You didn’t understand the “small battery for buffering, to shut down gracefully in case of power loss” part, the battery (not the car battery) doesn’t keep it running for days, it keeps it running for a few minutes in case you restart the engine and after x minutes without main power it tells the device to shut itself off. The last part you have to work on it a little, but not impossible.
So then I’d assume there’s some kind of small networked controller that talks back to the router that runs a shut down script or something? Otherwords, how does the battery tell the device to shut itself off?
