1. Short Description
Maintenance-Free Buffer Modules for Buffering
Power Failures
– Completely maintenance-free due to the capacitorbased energy storage device
– Narrow design saves space on the DIN rail
– Maximum system availability through reliable
signaling
– Increased buffer time for critical devices
With QUINT BUFFER buffer modules, back-up
power is stored in capacitors that are completely
maintenance-free. The modules extend the mains
buffering time of the power supply for 200 ms at 20 A,
and for even longer with a lower current consumption.
According to statistics, this solution addresses 80% of
all mains failures.
The buffer module also has increased energy
capacity for peak load demands.
In addition, modules can be connected in parallel to
extend the buffer time.
The devices have a narrow and uniform design,
which makes them ideal for use on the DIN rail where
space is limited. In addition, short wiring paths ensure
order and clarity in the control cabinet.
The power status must be determined quickly so that
the right decision can be made in an emergency.
Optimum signaling is thus required for maximum
system availability. A floating PDT contact and an LED
are provided for function monitoring.
The connected devices can be divided into buffered
and unbuffered loads using the isolated input. This
extends the buffer time, which depends on the output
current. If only fused, critical devices are protected, the
buffer time is increased significantly. In addition, the
isolated input protects the connected devices against
errors in the internal network.

4. Safety Notes and Warning
Instructions
To ensure that the device can be operated safely
and all functions can be used, please read these
instructions carefully.
Caution: Never carry out work when the
power is turned on, this is highly
dangerous.
QUINT BUFFER is a built-in device. Installation and
startup must only be carried out by qualified
personnel. The relevant country-specific regulations
(e.g., VDE, DIN) must also be observed.
Before startup it is particularly important to ensure
that:
• All supply lines have sufficient fuse protection and
are the correct size.
• All output cables are the correct size for the maximum
device output current or have separate fuse
protection.
• Sufficient convection is ensured.

5.1. Mounting
The buffer module can be snapped onto all
DIN rails according to EN 60715 and should be
mounted horizontally (input terminal blocks facing
downwards).

5.2. Narrow Mounting Position
The device is supplied ready for installation in a
narrow mounting position.
Mounting:
Place the module with the DIN rail guideway on the
top edge of the DIN rail and then snap it downwards.
Removal:
Release the snap-on catch using a screwdriver and
then detach the module from the bottom edge of the
DIN rail.
5.3. Flat Mounting Position
A flat mounting position can be achieved by mounting
the module onto the DIN rail at a 90° angle. To do this,
mount the DIN rail adapter (UTA 107) 7 as shown in
Figure 07. No additional assembly material is required.
Mounting screws: Torx T10 (torque 0.8 - 0.9 Nm).

For reliable and safe-to-touch
connections: Strip 10 mm (0.39 in.)
from the input and output side
connector ends and 7 mm (0.28 in.) from the signal
connector ends.
To maintain UL approvals, use copper cables, which
are designed for operating temperatures > +75°C
(+167°F). To meet GL requirements, unused terminal
compartments should be closed.
5.5. Input (1, Figure 04, Figure 08)
The buffer module is connected to the output of the
power supply via the "+" and "-" screw connections of
the 24 V DC input (4-pos. connection). The output is
isolated from the input by the internal diode.
The stored power is only supplied to the output
(Fig. 08a).
If isolation is not required, the buffer module can also
be connected to the power supply as a 2-pos.
connection via the "+" and "-" screw connections of the
DC output (Fig. 08b).
Fuse
Further device protection is not required, as an
internal fuse is present.
If the internal fuse is blown, this is
most probably due to a device fault.
In this case, the device should be
checked in the factory.

5.6. Output (2, Figure 04, Figure 08, Figure 10)
All loads that must be supplied by the power stored
in the buffer module in the event of a supply voltage
failure ("Buffered Load"), are connected to the "+" and
"-" screw connections of the DC output.
It is recommended that all other loads, which do not
require buffering in the event of a supply voltage failure
("Unbuffered Load"), are connected in parallel to the
power supply. This increases the buffer time, as this
time depends on the output current (see Figure 10).
The internal diode ensures that the buffered loads
are isolated from the unbuffered loads.
5.7. Signaling Output
The Power Good signal output is connected via the
"Power Good" and "GND" screw connections. The
24 V DC signal can be loaded with 20 mA maximum.
6. Method of Operation
QUINT BUFFER supplies all connected devices with
a regulated 24 V DC voltage without interruption for a
load current of up to 20 A. When the 24 V supply
voltage is applied, the integrated capacitor-based
energy storage device is charged. In the event of a
supply voltage failure, the stored power ensures that all
connected devices continue to operate without
interruption for up to 4 seconds.
6.1. Output Voltage
The output voltage of the buffer module corresponds
to the usual supply voltage. If the input voltage drops
more than 1 V in the space of 0.1 seconds, buffering is
enabled and the output voltage is regulated to this
19

value. The minimum switching threshold is 22 V.
The device is electronically short-circuit-proof and
idling-proof. In the event of an error, the output voltage
is limited to 35 V.
6.2. Signaling
The active signal output and an LED provide function
monitoring. The signal output is connected via the
"Power Good" and "GND" screw connections.
