Power Supply, Primary Switch Mode, Narrow Design – MINI-PS-100-240AC/10-15DC/2
6.4. Output ( 2 , Figure 9)
The 10 - 15 V DC connection is made using the "+"
and "–" screw connections on the screw connection 2 .
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 20 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.
DC OK LED
The green DC OK LED enables local function
evaluation in the control cabinet.
LED ON
Normal operation of the power supply
LED OFF a) The output voltage is ≤ 0.9 x U N .
There is a secondary load short circuit or overload
outside the POWER BOOST area.
b) No mains voltage is present or there is a device fault.

7.1. Output Characteristic Curve (Figure 10).
The device can supply a nominal output current of
2 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 2.3 A.
At temperatures up to 60°C (140°F), the POWER
BOOST provides a short-term output current of 2.3 A
for a few minutes.

With high loads, the working point demonstrates the
U/I characteristic curve shown in Figure 10.
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 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.
