The R&S®NGE100B power supply series consists of
the R&S®NGE102B two-channel power supply and the
R&S®NGE103B three-channel power supply. Both instru-
ments provide up to 33.6 W output power per channel.
Unlike most power supplies in this class, the
R&S®NGE100B power supplies feature 100 % electrically
equivalent output channels. All outputs are earth-free and
short-circuit-proof. The output channels can be combined
in serial or in parallel to achieve higher voltages or higher
currents (up to 96 V or up to 9 A using all three channels
of the R&S®NGE103B).
All basic functions of the R&S®NGE100B power supplies
can be operated via direct keys on the front panel. The
rotary knob plays the central role in adjusting the voltage
and current and setting the limits for the multipurpose
protection functions. The operating conditions of all chan-
nels are displayed on the screen simultaneously. Active
channels are indicated by the illuminated channel key. Ac-
tive outputs are shown in green when working in constant
voltage mode and in red when working in constant current
mode. Inactive outputs are displayed in white.

At a glance
To safeguard the instrument and the device under test
(DUT), the R&S®NGE100B power supplies provide a variety
of protection functions. For each channel, users can sepa-
rately set the maximum current (electronic fuse, overcur-
rent protection, OCP), the maximum voltage (overvoltage
protection, OVP) or the maximum power (overpower pro-
tection, OPP). If such a limit is reached, the affected out-
put channel will be switched off. Overtemperature protec-
tion (OTP) prevents overheating of the instrument.
In industrial applications, power supplies are often in-
stalled in 19" racks. The R&S®HZC95 rack adapter allows
the power supplies to be mounted in racks, including
in combination with R&S®HMC test instruments. The
R&S®NGE100B power supplies can be remotely controlled
via USB or optionally via Ethernet or even via wireless
LAN.
