2 Welcome to R&S NGE100B
The two or three-channel power supply series are based on a classical transformer
concept with high efficiency electronic pre-regulators and secondary linear regulators.
This concept allows the instrument to achieve the high output power within a minimum
space, high efficiency and lowest residual ripple.
The R&S NGE100B power supply series feature galvanically isolated, floating overload
and short-circuit proof outputs with adjustable power ratings. The outputs can be con-
nected in series or in parallel, thus making high currents and voltages available.
Multi-purpose protection functions are available for each channel which you can set
separately, such as overcurrent protection (FUSE), overvoltage protection (OVP), over-
power protection (OPP) and overtemperature protection (OTP). If such a limit is
reached, the affected output channel is automatically turned off and an indicator mes-
sage (FUSE, OVP, OPP or OTP) is displayed. The overcurrent protection can be linked
to other channel (FuseLink function). In this case, all linked channels are turned off
when the set channel reaches its limit.
The EasyArb function allows channel 1 (Ch 1) to have freely definable voltage and cur-
rent sequences with a timeframe as short as 10 ms. It allows you to vary the voltage or
current limit during a test sequence, for example to simulate different charging condi-
tions of a battery. With EasyRamp function, the R&S NGE100B provides the operating
condition to simulate the continuous rise of the supply voltage within a defined time-
frame of 10 ms to 10 s.
Four data lines of the digital I/O interface are mutually independent and can be used as
trigger input or trigger output separately. Various trigger conditions (e.g. fuse tripped,
voltage, current, indicator messages) can be used to turn off, on or invert the output
state when the trigger condition is met.
All R&S NGE100B power supply series are equipped with a color LCD display (320 x
240 pixels resolution). The R&S NGE100B comes with a USB interface and optional
LAN (LXI) interface.
