This uninterruptible power supply (UPS) controller
1606-XLS240-UPS is an addition to standard 24V
power supplies to bridge power failures or voltage
uctuations. Expensive downtimes, long restart
cycles and loss of data can be avoided.
The DC-UPS includes a professional battery
management system which charges and monitors
the battery to achieve the longest battery service life
as well as many diagnostic functions that ensure a
reliable operation of the entire system.
A unique feature of the 1606-XLS240-UPS is that only
one 12V battery is required to buer the 24V output.
This makes matching batteries unnecessary and
allows a precise battery charging and testing.
The 1606-XLS240-UPS requires one external 12V battery
for which two preassembled battery modules
are available: a lightweight 7Ah battery that can be
mounted on the DIN rail and a 26Ah module that
can be panel-mounted for longer buer times.
In addition to the 1606-XLS240-UPS, the
1606-XLS240-UPSC UPS includes the same controller
with an integrated 5Ah battery.
