1-Phase Power Supply, Primary Switch Mode for Use in Potentially Explosive Areas –
QUINT 24 V DC/5 A/EX
Active Signal Output (Figure 13)
The 24 V DC signal is between the "DC OK" and "-"
connection terminal blocks and can be loaded with
40 mA maximum. This signal output indicates that the
output voltage has fallen more than 10% below the set
value when "active high" changes to "low".
The DC OK signal is isolated from the power output.
This ensures that a separate supply does not enter
from devices connected in parallel.
Output 24V DC
The 24 V DC signal can be connected directly to the
logic input for evaluation.

Signal Loop (Figure 14)
The two signal outputs mentioned above can be
combined easily.
Example: Monitoring two devices
Use the active alarm output of device 1 and loop in
the electrically isolated alarm output of device 2. In the
event of an error, a group error message is generated.
It is possible to loop any number of devices.
This signal combination saves on wiring costs and
logic inputs.
DC OK LED
The green DC OK LED enables local function
evaluation in the control cabinet.

7. Function
7.1. Output Characteristic Curve
The device can supply a nominal output current of
5 A up to an ambient temperature of 60°C (140°F).
With an ambient temperature of up to 40°C (104°F) the
device continuously supplies an output current of 7.5 A.
At temperatures up to 60°C (140°F), the
POWER BOOST provides a short-term output current
of 7.5 A for a few minutes.
With high loads, the working point demonstrates the
U/I characteristic curve shown in Figure 15.
On an overload or short circuit, the entire output
current I BOOST is provided permanently at a reduced
output voltage.
Once the overload or short circuit has been removed,
the entire set secondary voltage is available again.
The U/I characteristic curve ensures that both heavy
capacitive loads and devices with DC/DC converters
can be supplied by QUINT POWER in the input circuit
without any problems.
Connected fuses are reliably tripped. The selectivity
in your system con ? guration is ensured at all times.
