That's what it looks like. Seems they've refined the product brochures
and datasheets.
" If the connected supply fails, the battery is then connected to the
load (buffer mode), a step up converter is
used to maintain the selected output voltage level, Vnom - 6% (typical)."
They also lead you to believe that it still has the TSP remote control.
"The module provides two inputs to connect two power supplies to
facilitate a redundant system. If one of the two connected sources
fails then the second supply will provide energy to load maintaining the
desired operation of the unit. The unit is designed to function
with the TRACO POWER TSP series, but due to its standalone nature it can
be used with any type of fully stabilized 24V or 48V power
supply"

Am I understanding that unit correctly? It has a step-up converter
from the battery, so unlike the BCM-12/24/48, the output will always
be regulated 24 or 48 volts, not battery voltage? Also that it only
needs a 12V battery? And can work with any DC power supply since
unlike the BCM it doesn’t control the power supply output voltage?

This is where the BCMU-360 makes sense, 24 or 48v in one unit.

I believe the BCM does have a battery test, maybe not as fancy.
My reaction is 60W is kind of low, plus I can use 3 different sizes
of TSP from 90 to 360W with the same BCM or alone as just a power
supply or add the BCM later. And if it fails, I only have to replace
the failed unit. And if the BCM fails, the site can run on just the
TSP if I don’t have a spare. And there is a 48V version of the BCM.
So it seems more flexible.

Has anyone looked at the Traco TBL-BC before? It seems to do a lot
things other than basic battery charging and even temperature
compensation. It's not all that big, but may be good for repeater
sites. Seems to be about the same cost for a bigger power supply and
regular BCM as this guy, but the alternative wouldn't have the
battery testing system.
