Output characteristic
Response characteristic of the power
supply when exceeding the specified
output values.
The output characteristics are:
Response time
The period of time required after a defined
load change until the output voltage is
again within the tolerance range.
Operating temperature
The temperature range that an operating
device must not exceed.
Drift
Output voltage changing over time or the
temperature.
DC/DC transducer
Device that converts a given direct voltage
into a different direct voltage by means of
a switching regulator.
Inrush current
The peak current caused during switch-on
of a power supply by the charging current
of the filter capacitors. It is limited by the
input impedance but can also be limited
further by special components.

Explanation of important technical terms
wipos
Constant current mode
When exceeding the nominal current,
the device supplies a constant current
independent of the voltage.
Fold-back mode
When exceeding the nominal current,
the output voltage decreases to zero
while the current subsides.
Hiccup mode
The device switches off when the
nominal current is exceeded, but
switches on again periodically and
checks whether the overload is still
applied. When the overload has
diminished, the device switches on
automatically.
Over-current switch-off mode
When exceeding the nominal current,
the device switches off and must be
manually switched on again after the
overload is removed.
Radio interference,
electromagnetic interference
Unwanted high-frequency disturbance
variables caused by switching processes
within the power supply. We distinguish
between conducted and radiated radio
interference. Conducted interferences are
reduced to permitted values by means of
filters, while radiated interferences can be
kept within the permitted limits by means
of optimized PCB creation and screening.
Insulation voltage
Insulation voltage is the maximum voltage
that can be applied between two isolated
circuits.
Cooling
Heat transfer from components that are
producing power loss. We distinguish
between thermal radiation, convection
(natural and forced convection with fan),
and thermal conduction to an external
heat exchanger.
Short-circuit protected
Protection of the power supply against
overload and short circuit.
See the output characteristic for various
options.
Storage temperature
The temperature range at which a device
can be stored (not operated) without
being damaged.
Load regulation
Change of output voltage at a defined load
change.
Power reduction, derating
Reduction of output power required under
certain circumstances such as when
exceeding a defined temperature.
Power factor
Ratio between real power and apparent
power. In a switch-mode power supply,
the power factor normally becomes
smaller than 1 due to a non-sinusoidal
current input.
Hold-up time
The period of time in which the output
voltage is still controlled after the mains
voltage has dropped completely.
Line regulation
Change of output voltage at a defined
mains voltage change while all the other
parameters (load) are kept constant.
Nominal output voltage
Output voltage specified for the device.
The voltage can be increased or
decreased within specified limits below
and above the nominal value.
Temperature coefficient
Output voltage change depending on the
temperature.
Ambient temperature
Temperature of the steady air around the
device. It is normally measured within a
radius of approx. 10 mm around the
operating device.
Overshoot
Increase of the output voltage exceeding
the specific value due to a rapid load
change.
Overcurrent limitation
Protective mechanism against overload of
the power supply due to excessive output
current. Also see short-circuit current.
Efficiency
Relation between output power and input
power, normally indicated at full load and
nominal input voltage. Efficiency is one of
the most important features when
evaluating a power supply.
The difference between input power and
output power is converted into heat. Any
increase in efficiency therefore results in
the heat load on the components being
reduced and the service life of the device
being increased. Even small
improvements in efficiency will result in
drastic changes in the service life.
