Protection functions to safeguard instrument and
DUT
Multipurpose protection functions are not standard
in power supplies in the basic class. Here again, the
R&S®NGE100B power supply series raises the bar.
For each channel, users can separately set the:
❙ Maximum current (electronic fuse, overcurrent
protection, OCP)
❙ Maximum voltage (overvoltage protection, OVP)
❙ Maximum power (overpower protection, OPP)
If such a limit is reached, the affected output channel will
be automatically switched off and a message (FUSE, OVP
or OPP) will be displayed. The overcurrent protection can
be linked to other channels (FuseLink function). In this
case, the channel exceeding the maximum current level
and all linked channels will be switched off.
Even the delay time of the electronic fuses can be set.
With this functionality, users can define the behavior of the
power supply to prevent too early switch-off due to a short
current spike.
Naturally the R&S®NGE100B power supplies come with in-
ternal overtemperature protection to switch off the instru-
ment in the case of pending thermal overload.
Modern architecture, small, compact and quiet
Universal power supplies need to fulfill many demands:
❙ They have to work reliably even in countries with
unstable electricity
❙ Power supplies should be small and compact. The
switching regulator makes the R&S®NGE100B work very
effectively. It reduces weight and size and requires a
lower fan speed, which results in low noise
❙ Power supplies should provide stable output voltages/
currents with low ripple. This is implemented by using
linear control circuitry for stabilization
Tailored to be used in education, labs and system
racks
Power supplies in the basic class offer the functional-
ity you need in daily work – and with the R&S®NGE100B
power supply series – even a bit more. Students should
find all the functions they need for training, but should
not be confused by exotic functions. Used in standard
applications on the bench, power supplies should be af-
fordable and robust, offering the necessary accuracy
and speed. If the instrument is to be installed in a rack,
remote control and rack integration are recommended.
The R&S®NGE100B power supply series fullfills all these
requirements.
All channels galvanically isolated and earth-free
The R&S®NGE102B and R&S®NGE103B power supplies
offer the choice between two or three channels. The cir-
cuitry of each single channel is completely separated from
the others, there is no connection to chassis ground. This
makes it easy to combine the channels to drive bipolar
circuitries that might need +12V/–12V, for example, and
avoids any ground problems in complex DUTs.
All channels electrically equivalent with the same
voltage, current and power
In contrast to other power supplies on the market, the
R&S®NGE100B power supplies feature electrically identical
channels. Offering the same voltage, current and power,
there is no limitation in selecting a channel for a specific
application. Every single channel can be seen as a sepa-
rate power supply.
Parallel and serial operation
Because all channels are electrically equivalent, they can
be combined in serial mode to achieve higher voltages.
Up to 96V can be achieved with the R&S®NGE103B, up to
64V with the R&S®NGE102B. In parallel mode, the chan-
nels can be bundled for higher current. Up to 6A can be
achieved when combining two channels. Using all three
channels of the R&S®NGE103B, even 9A are possible.
Short-circuit-proof outputs
Whatever might happen when unskilled students gain
their first experience in practical work with electronics,
all outputs of the R&S®NGE100B power supply series are
short-circuit-proof and will therefore not be damaged.
