output voltage set upon delivery is 48 V DC.
The output voltage can be adjusted from 40 to
56 V DC on the potentiometer

Protecting the Secondary Side:
The device is electronic short-circuit-proof and idling-
proof. In the event of an error, the output voltage is
limited to a maximum of 60 V DC.
It should be ensured that all output cables are the
correct size for the maximum output current or have
separate fuse protection.
The secondary side cables should have large cross
sections to keep voltage drops on the cables to a
minimum.
6.7. Signaling
Both DC OK outputs are used for preventive function
monitoring of the power supply. An electrically isolated
signal contact 44
44
and an active DC OK signal 33
33
are
available. In addition, the DC OK LED 66
66
can be used
to evaluate the function of the power supply directly at
the installation location.
Electrically Isolated Contact (Figure 12)
When opened, the electrically isolated signal contact
indicates that the output voltage has fallen more than
10% below the set value. Signals and ohmic loads up
to a maximum of 60 V and currents up to a maximum
of 0.5 A can be switched.
With heavy inductive loads, e.g., a relay, a suitable
protective circuit (e.g., free-wheeling diode) is required.
Active Signal Output (Figure 13)
The 24 V DC signal is between the "DC OK" and "-"
connection terminal blocks and can be loaded with
20 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.
The 24 V DC signal can be connected directly to the
logic input for evaluation.
