Uninterruptib

le Power Supply Units for Buffering

Long-Term Power Interruptions

•

Saves space thanks to the compact, uniform design

• Integrated diode saves money through isolation of
loads

• Maximum system availability through optimum
battery management and reliable signaling

• Minimum installation time due to ready-to-use
plug-in bridges and integrated timeout
QUINT-DC-UPS uninterruptible power supply units

with long-life lead-acid batteries provide long buffer
times at high currents. Even in the event of a longer
supply voltage failure, the units ensure that all
connected devices continue to operate without
interruption.

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 high level of availability and the particularly long

service life of the battery modules are achieved
through professional battery management. An
automatic presence check (every minute), automatic
quality test (once a week), temperature-determined
charging, and electronic overcurrent protection ensure
the battery modules are ready to operate at all times.
Power is therefore available in the event of an error and
the service life of the battery module is maximized.

The actual state must be determined quickly so that

the right decision can be made in an emergency.
Optimum signaling is thus required for maximum
system availability. Three floating PDT contacts and
three LEDs are provided for function monitoring, which
indicate all the operating states clearly.

So that relay signaling is more reliable and more

durable than before, an additional positive supply
output has been provided. The contact, which is
current-limited and resistant to continued short circuits,
is located next to the relay connections and enables
easy bridging. In the event of wiring errors, the short­circuit protection prevents any welding of the relay
contacts. This ensures that the user can rely on an OK
signal. Even in the event of connection errors, currents
remain below 100 mA, which prevents damage to the
relay contacts.

A system is switched off after a specific time that can
be set on the device or by an external signal. No
additional installation is required for shutdown. In
addition, ready-to-use plug-in bridges minimize the
installation time.

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 critical devices are protected using
fuses, smaller battery modules can be used that save
money and space in the control cabinet. In addition, the
isolated input protects the connected devices against
errors in the internal network.

5.4. Connection

The following cable cross sections can be connected:

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 (1111, Figure 04, Figure 08)

The QUINT-DC-UPS is connected to the 24 V DC
output of the power supply via the "Input +" and
"Input -" terminal blocks. The output is isolated from the
input by the internal diode. The stored power is only
supplied to the output. The device is protected against
overcurrent and short circuit by an internal input fuse.

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.

Figure 08

PHOENIX CONTACT page 7 of 9

5.6. Output

All devices that must be supplied without interruption
in the event of a supply voltage failure
("Buffered Load"), are connected to the "Output +" and
"Output -" terminal blocks of the DC output (Fig. 08). It
is recommended that all other loads, which do not
require buffering ("Unbuffered Load"), are connected to
the 24 V DC output of the power supply.

This increases the buffer time, as this time depends
on the output current (see Fig. 10). The internal diode
ensures that the buffered loads are isolated from the
unbuffered loads.

5.7. Battery Module

The battery module is connected to the
QUINT-DC-UPS via the "Battery +" and "Battery -"
terminal blocks. To interrupt the charge/discharge
current of the battery module, the "Battery module
selection" selector switch

$ must be set to "Service".

The fuse on the battery module
must be removed when installing or
replacing the battery module.

The QUINT-DC-UPS is optimized for use with
QUINT-BAT/24DC type battery modules.
The following battery modules are recommended:

QUINT-BAT/24DC/3,4AH (Order No. 2866349)

QUINT-BAT/24DC/7,2AH (Order No. 2866352)

QUINT-BAT/24DC/12AH (Order No. 2866365)

When using QUINT-BAT/24DC/3,4AH, the maximum
output current of 25 A must not be exceeded.
Following successful installation, the capacity of the
connected battery module must be selected using the
"Battery module selection" rotary switch

$.

5.8. Signaling Outputs

The signal outputs are connected via terminal blocks
11/12/13

4, 21/22/23 5 or 31/32/33 6. The contacts

are floating contacts. The plug-in bridge provided can
be used to supply +24 V to grouped contacts 11,21,31.
This means that N/C contacts 12,22,32 and N/O
contacts 13,23,33 can be evaluated as switching
outputs with 0 V and +24 V voltage levels.

5.9. Remote Shutdown ("Remote", Fig. 12)

The device has a UPS remote shutdown function for
specific shutdown.
Remote shutdown must be deactivated for the device
to switch to buffer mode in the event of a supply voltage
failure.

Remote Shutdown Off

• The "Remote shutdown R1" and "Remote

shutdown R2" terminal points are short circuited

(e.g., with a plug-in bridge) OR

The "Remote shutdown R2" terminal point is

supplied with a 24 V DC voltage

• The QUINT-DC-UPS switches to buffer mode in the

event of a supply voltage failure

Remote Shutdown On

• The "Remote shutdown R1" and "Remote

shutdown R2" terminal points are not connected

• All LEDs are off

• The QUINT-DC-UPS does not switch to buffer mode

in the event of a supply voltage failure, instead the

device is shut down. When the supply voltage is

reapplied, the battery module is charged and the

device remains off until remote shutdown is

deactivated.

• Connected loads are supplied as long as the supply

voltage is present

6. Setting Options on the Device

(Fig. 13)

6.1. Buffer Time Setting

Buffer mode can be exited after a predefined time
has elapsed or by external
shutdown (see 6.9).
If the device is to be shut down after a specific time
has elapsed, the time can be set via the
selector switch § on the front of the device.
When the supply voltage is reapplied, the device
can switch to buffer mode again.

6.2. Battery Module Setting

Before startup, the capacity of the battery module
used must be set on the device via the selector switch
$. When replacing the battery, the selector switch
must be set to "Service" (see also 6.7).

7. Method of Operation

In the event of a power failure at the output, the QUINT-DC-UPS supplies all connected devices with a 24 V DC
voltage without interruption at a load current up to 40 A. When the 24 V supply voltage is applied, the connected
battery module is charged. In the event of a supply voltage failure, the battery module is connected to the output,
and the stored power ensures that all connected devices continue to operate without interruption. The professional
signaling via function LEDs and floating PDT contacts enables reliable evaluation of all the main operating states.

7.1. Output Voltage

In normal operation, the QUINT-DC-UPS output voltage corresponds to the usual supply voltage. If the supply

voltage drops more than 1 V in the space of 0.1 seconds or falls below the minimum threshold of 22 V, the device
switches to buffer mode.
If the output voltage drops below 20.4 V in buffer mode, this is indicated by the Alarm indicator.
If the output voltage drops to 19.2 V because the battery module is flat, the device is shut down completely. When
the supply voltage is reapplied, the device automatically switches on again. The device is electronically
short-circuit-proof and idling-proof.

7.2. Signaling

Three floating PDT contacts and three indicators are provided for function monitoring.

xx - xx: Contact closed,
1x Alarm, 2x Battery Mode, 3x Battery Charge
x1 group contact, x2 N/C contact, x3 N/O contact

7.3. Temperature Response

The charging rate of the connected battery module depends on the temperature.

7.4. Testing the Battery Module

A quality test is carried out on the battery module once a week and its presence is verified every minute.
A negative test result is indicated by the Alarm indicator.
