The power from the controller to the radio board is essentially the battery power. So with full battery it's about 13.4V and it takes about 26 hours at 3.5W to reach 11.1V. This is a gradual voltage slope so you could set a warning at 11.5V and you'd have some time to take some action. At 11.1V the controller turns off the power to the radio in order to keep the battery from over discharging. If discharge batteries too much it reduces the life of batteries.
If you want to run at lower battery voltages, you can add one of our TP-DCDC-1218 or TP-DCDC-1224 DCDC or TP-DCDC-1248 DC to DC Converters between the battery and the radio board. These units will give regulated 18V or 24V or 48V DC voltage from inputs as low as 9V. They have a built in POE inserter and 2 isolated power inputs.

The RB230's and I think as well the RB532 could/would over SNMP report power levels and temps maybe the newer boards can't report temp but can report power over SNMP. If I didn't understand Scott incorrectly the power supplied out from the controller is stabilized so you will either work or your dead. So to use DC voltage report you would need a separate board feeding directly of the battery and as power on the battery start to drain your NMS would have to trigger on a low voltage problem. There is another issue here.. That is that the UPS battery is 12V and most RB dies or fail when the power goes under 11V. So the window of opportunity would be very small. Or am I missing something here? / Eje -----Original Message----- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Gino Villarini Sent: Saturday, August 01, 2009 3:19 PM To: WISPA General List Cc: WISPA General List Subject: Re: [WISPA] TP--UPS-DC-12-9 Iirc some mikrotik boards report dc voltage Sent from my Motorola Startac...
