6.4. Output ( 2 , Figure 9)
NEC Class 2 power supply when installed with a 4.2
amp maximum, UL listed fuse or circuit breaker in the
output of the power supply. This procedure must be
followed to meet NEC Class 2 requirements
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 35 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.
Active signal output ( 3 , Figure 10)
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 below 21.5 V DC 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.

7.1. Output Characteristic Curve
The device can supply a nominal output current of
Figure 11
The U/I characteristic curve ensures that both heavy
capacitive loads and devices with DC/DC converters
can be supplied by MINI 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.
4 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 5 A.
At temperatures up to 60°C (140°F), the POWER
BOOST provides a short-term output current of 6 A for
a few minutes.
With high loads, the working point demonstrates the
U/I characteristic curve shown in Figure 11.
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.
