Description
The TRIO-UPS-2G uninterruptible power supply (UPS) with
integrated power supply unit is used to ensure that secure
DC power for critical electrical loads continues to be
supplied in the event of disturbances in the power supply
network, e.g. due to mains breakdown or failure. In the event
of such a disturbance, the UPS switches to battery
operation without interruption so that connected loads
continue to be continuously supplied. In this operating
mode, the output voltage is directly dependent on the
battery voltage. When mains power is restored, the UPS
automatically returns to normal operation. The connected
loads are again supplied via the power supply network and
the battery is charged at the same time. The TRIO-UPS-2G
uninterruptible power supply (UPS) is designed specifically
for supplying industrial PCs (IPCs).

Mounting the universal DIN rail adapter
Wall mounting
The UWA 130 universal wall adapter (Order No. 2901664) is
used to attach the uninterruptible power supply directly to
the mounting surface.
The use of the universal wall adapter is recommended under
extreme ambient conditions, e.g., strong vibrations. Thanks
to the tight screw connection between the uninterruptible
power supply and the universal wall adapter or the actual
mounting surface, an extremely high level of mechanical
stability is ensured.
Rotated mounting position (270° Y-axis)
For rotated installation, use the existing universal DIN rail
adapter and the Torx screws available.
The maximum tightening torque of the Torx
screw (Torx® T10) is 0.7 Nm.
To mount the uninterruptible power supply in a rotated
position, fasten the universal DIN rail adapter to the left side
of the housing as follows:
1. Remove the screws for the factory-installed universal
DIN rail adapter using a suitable screwdriver (Torx 10).
2. Remove the universal DIN rail adapter from the rear of
the uninterruptible power supply.
3. Position the universal DIN rail adapter so that the
mounting holes match the hole pattern on the left side of
the housing.
4. Insert the Torx screws into the appropriate hole pattern
on the universal DIN rail adapter so that the necessary
drill holes on the device can be accessed.
5. Screw the universal DIN rail adapter onto the device.
107432_en_02
The UWA 130 is attached to the
uninterruptible power supply by means of the
Torx screws of the universal wall adapter.
The maximum tightening torque of the Torx
screw (Torx® T10) is 0.7 Nm.
Make sure you use suitable mounting material
when attaching to the mounting surface.

It must be possible to switch the device off using a suitable
disconnection device outside the power supply. For
example, the primary-side line protection is suitable for this
(see technical data).
An internal, approved AC/DC fuse is available as device
protection. Additional device protection is not required.
If an internal fuse trips, this is due to a device
fault. In this case, the device must be
inspected in the factory. Opening the device
or repairing it yourself is prohibited.

The uninterruptible power supply is electronically shortcircuit-proof and idling-proof. In the event of an error, the
output voltage is limited.
It must be ensured that all output cables are dimensioned
appropriately for the maximum output current or have
separate protection.
The connecting cables on the secondary side should have
large cross sections to keep the voltage drops in the cables
as low as possible.

You can use the Bat.-Start signal terminal to start the UPS
without supply voltage on the input side and create an
autonomous supply for the load. To do this, you must
connect the Bat.-Start signal terminal to the SGnd signal
terminal.
The output voltage provided at the load matches the battery
voltage.
The maximum duration of the autonomous supply for the
load depends on the charging state of the battery.
The signaling corresponds to the signaling for battery
operation (see Signaling section).
To exit autonomous operation, you must disconnect the
Bat.-Start signal terminal and the SGnd signal terminal.

Method of operation
10.1
Output characteristic curve
was prior to time point t1. If the request to supply the load still
exists when the time intervals t2 to t3 have expired (at least
4 * tBoost), a new cyclical switching of the dynamic power
reserve occurs, to a total of 70%.
UOUT [V]
The uninterruptible power supply works with a dynamic
power reserve – the dynamic boost – in accordance with the
U/I characteristic curve shown in the illustration. In the event
of a secondary-side short circuit or overload, the output
current is limited to 1.5 x IN. The device does not switch off,
but instead continues to supply the output current. The
secondary voltage is then reduced until the short circuit is
eliminated. The U/I characteristic curve with the dynamic
power reserve makes it possible to provide high switch-on
currents of capacitive loads or inductive loads reliably.

Dynamic Boost
The following example is used to explain how the
uninterruptible power supply dynamic boost functions.
Example:
The uninterruptible power supply supplies a connected
base load of 80% until time point t1 (see illustration,
schematic diagram of the dynamic boost behavior). If an
additional load is activated while the device is in operation,
the dynamic boost is requested for the period of time t1 to t2.
The uninterruptible power supply provides the maximum
dynamic power reserve of an additional
70% (ΔPdyn. boost = 1.5 x IN x UN - P initial load).
11
Battery management
The TRIO-UPS battery management is divided into two tests
that are performed cyclically during normal operation.
11.1
Battery presence test
The battery presence test is used to detect whether a
correctly installed battery is present. If this is not the case,
the test fails and the green and red LED control lamps come
on and stay on.
11.2
Quality check of battery
The battery quality test is a life cycle test.
When the maximum charging time has been exceeded,
conclusions can be drawn regarding the maximum service
life of the battery, for example. If an event arises, the green
and red LED control lamps come on and stay on.
11.3
Battery charging
The device has a maximum charging current of 3 A.
Refer to the following table for the times required to recharge
a fully discharged battery.
As such, the requested overall total power corresponds to
150% of the nominal power. This power can be accessed for
at least 5 s in the event that the output voltage remains the
same. On reaching time point t2, the dynamic boost is once
more returned to the output value of the base load for
thermal offloading of the uninterruptible power supply. In this
case, the base load amounts to the same value of 80%, as it

You can support the main charging operation by connecting
an additional power supply unit to the battery in parallel to
the UPS. This can speed up the changing process by as
much as 30%. If you use this procedure, note the following:
– The output voltage of the additional power supply unit
must be less than the minimum float charge end
voltage. When using Phoenix Contact VRLA batteries,
they should be set to 26.5 V (measured at the battery
connection terminal block, without load)
– The aggregate charging current may not exceed the
maximum permissible charging current for the battery
– To prevent any current from flowing back into the power
supply unit, install a diode decoupling module

A data cable is required for communicating with a PC or a
higher-level controller.
The device provides both the IN nominal output current and
the Idyn. BOOST dynamic output current at ambient
temperatures up to +60 °C. For ambient temperatures
above +60°C, the ambient power must be decreased by
2.5% per Kelvin increase in temperature. For ambient
temperatures above +70°C or in the event of a thermal
overload, the device does not switch off. The output power
will be decreased by enough to allow device protection.
Once the device has cooled down, the output power will be
increased again.

The uninterruptible power supply can be operated at an
installation height of up to 2000 m without any limitations.
Different data applies for installation locations above
2000 m due to the differing air pressure and the reduced
convection cooling associated with this.

Parallel operation
Devices of the same type can be connected in parallel to
increase both redundancy and power. No further
adjustments to the default setting are necessary.
To ensure symmetrical current distribution, we recommend
that all cable connections from the power supply unit to the
busbar are the same length, and have the same conductor
cross-section.
Depending on the system, a protective circuit should be
installed at each individual device output (e.g. decoupling
diode or DC fuse) for parallel connection of more than two
devices. This prevents high return currents in the event of a
secondary device fault.
15.1
Increasing power
When two uninterruptible power supplies are connected in
parallel, the output current is increased to 2 x IN. Parallel
connection for increased power is used when extending
existing systems. If the individual uninterruptible power
supply does not cover the current consumption of the most
powerful load, parallel connection of uninterruptible power
supplies is recommended.
To increase performance, it is imperative that
both UPS devices be supplied from the same
energy storage system.
Redundant operation
Redundant circuits are suitable for supplying systems which
place particularly high demands on operational reliability. If
a fault occurs in the primary circuit of the first uninterruptible
power supply unit, the second device automatically takes
over the complete power supply without interruption, and
vice versa. For this purpose, the power supply units to be
connected in parallel must be large enough to ensure that
the total current requirements of all loads can be fully met by
one power supply unit. External decoupling diodes or
ORING modules are required for 100 % redundancy.
