Power Supply Unit, Primary Switched, Narrow Design – MINI-PS-12-24DC/24DC/1
7.2. Temperature Response
The device can supply a nominal output current of 1 A
up to an ambient temperature of 60°C (140°F).
Kelvin temperature increase for ambient temperatures
above +60°C (140°F). At ambient temperatures above
+70°C (+158°F) or in the event of a thermal overload,
the device reduces the output power to protect itself
and returns to normal operation once it has cooled
down.
7.3. Parallel Operation
parallel to increase both redundancy and power. The
default setting does not have to be adjusted.
distribution can be ensured by precisely setting all
power supply units that are operated in parallel to the
same output voltage.
recommend that all cable connections from the power
supply unit to the DIN rail are the same length and have
the same cross section.
more than two power supply units a protective circuit
should be installed at each individual device output
(e.g., decoupling diode or DC fuse). This prevents high
return currents in the event of a secondary device fault.
7.4. Redundancy Operation
systems, which place particularly high requirements on
operational safety. If a fault occurs in the primary circuit
of the first power supply unit, the second device
automatically takes over the complete power supply
without interruption, and vice versa.
connected in parallel must be large enough that the
total current requirements of all loads can be fully met
by one power supply unit. External decoupling diodes
are required for 100% redundancy.
7.5. Increasing Power
n is the number of devices connected in parallel.
when extending existing systems. A parallel
connection is recommended if the power supply unit
does not cover the current consumption of the most
powerful load. Otherwise, the loads should be divided
over independent individual devices.
