Term Definition
DC-UPS Uninterpretable power supply with DC input.
Normal mode Describes a condition where the battery is charged, the input voltage is in range, and the
output is loaded within the allowed limits.
Buffer mode Describes a condition where the input voltage is below the transfer threshold level, the unit is
running on battery (buffering) and the output is loaded within the allowed limits.
Charging mode Describes a condition where the battery is being charged, the input voltage is in range and the
output is loaded within the allowed limits.
Inhibit mode Describes a condition where buffering is disabled on purpose by using the inhibit input of the
DC-UPS. (For example, for service actions, or to save battery capacity)
Buffer time Same as the term hold-up time.
This uninterrupted power
supply (UPS) controller with
integrated battery is a compact
addition to standard 24V power
supplies to bridge power
failures or voltage fluctuations.
Expensive downturns, 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 and many
diagnostic functions that ensure
a reliable operation of the entire
system.
A unique feature of the 1606-XLS240-UPSC is that only one 12V battery is
required to buffer the 24V output. This makes matching batteries unnecessary
and allows a precise battery charging and testing.
The power supply has one easy-to-change integrated 12V, 5 A high-current
VRLA battery.
In addition to the power supply, a separate UPS controller which requires an
external 12V battery is available when a longer buffer time is required.
The power supply includes these features:
• Compact size and easy installation
• Longest buffer time in class
• Easy battery access
• Stable output voltage in buffer mode
