Welcome to R&S NGL200
2 Welcome to R&S NGL200
The one or two-channel power supply series are based on a classical transformer concept with linear regulators. This concept allows the instrument to achieve highest accuracy and lowest residual ripple.
The R&S NGL200 power supply series feature galvanically isolated, floating overload
and short-circuit proof outputs. The outputs can be connected in parallel and serial to
get higher voltages, thus making high currents available.
Multi-purpose protection functions are available for each channel which you can set
separately, such as overcurrent protection (OCP), overvoltage protection (OVP) and
overpower protection (OPP). If such a limit is reached, the affected output channel is
automatically turned off and an indicator icon ( , , ) blinks on the display. In the
case of two-channel power supply, NGL202, the overcurrent protection can be linked to
the other channel. In this case, the linked channel is turned off when the other channel
reaches a limit.
Additionally, the R&S NGL200 is protected with overtemperature protection (OCP).
This safey feature protects the R&S NGL200 from getting overheated, when activated,
the channel outputs are turned off.
The Arbitrary function allows a freely definable voltage and current 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 conditions of a battery. With
Ramp function, the R&S NGL200 provides the operating condition to simulate the continuous rise of the supply voltage within a defined timeframe of 10 ms to 10 s.
All R&S NGL200 power supply series are equipped with a color LCD display (800 x
480 pixels). The R&S NGL200 comes with a USB and LAN (LXI) interface. Equipped
with a wireless LAN (WLAN) option, you can establish a network connection wirelessly .
The digital I/O interfaces installed at the rear panel is activated with an option, it provides a set of 4-bit digital interfaces that can be individually used as trigger inputs or
outputs.
The user manual contains description of the functionalities that the instrument provides. The latest version is available for download at the product homepage (http://

3.2 Ambient Conditions
The allowed operating temperature ranges from +5 °C to +40 °C (pollution category 2).
The maximum relative humidity (without condensation) is at 80 %.
During storage and transport, the temperature must be between -40 °C and +70 °C. In
case of condensation during transportation or storage, the instrument will require
approximately two hours to dry and reach the appropriate temperature prior to operation. The instrument is designed for use in a clean and dry indoor environment. Do not
operate with high dust and humidity levels, if danger of explosion exists or with aggressive chemical agents.
Any operating position may be used; however adequate air circulation must be maintained. For continuous operation, a horizontal or inclined position (integrated stand) is
preferable.
Specifications with tolerance data apply after a warm up period of at least 30 minutes
at a temperature of 23 °C (tolerance -3 °C/+ 7 °C).
The heat produced inside the instrument is guided to the exterior via temperature-controlled fan. Each channel has multiple temperature sensors which check the heat generation in the instrument and control the fan speed.
It is necessary to ensure that there is sufficient space around the instrument sides for
heat exchange. If the temperature inside the instrument increases to more than

Air circulation
Do not obstruct the ventilation holes!
This instrument is designed for supplying power on circuits that are only indirectly connected to the low voltage mains or not connected at all. The instrument is not intended
for measurements within the measurement categories II, III or IV; the maximum potential against earth generated by the user must not exceed 250 V peak in this application.
The following information refers solely to user safety. Other aspects, such as the maximum voltage, are described in the technical data and must also be observed.
The measurement categories refer to transients that are superimposed on the mains
voltage. Transients are short, very fast (steep) current and voltage variations which
may occur periodically and non-periodically. The level of potential transients increases
as the distance to the source of the low voltage installation decreases.
●
Measurement CAT IV: Measurements at the source of the low voltage installations
(e.g. meters)
●
Measurement CAT III: Measurements in building installations (e.g. power distribution installations, power switches, firmly installed sockets, firmly installed engines
etc.)
●
Measurement CAT II: Measurements on circuits electronically directly connected to
the mains (e.g. household appliances, power tools, etc.)
●
0 (instruments without measured measurement category): Other circuits that are
not connected directly to the mains
3.4 Mains Voltage
The instrument applies 50 Hz / 60 Hz mains voltages ranging from 100 VAC, 115 VAC
or 230 VAC (tolerance ± 10 %). Mains voltage switching is not intended. The input line
fuse is accessible externally. Power socket and fuse holder form a single unit.
You need to first disconnect the power cord from the connector before you can safely
replace the fuse (as long as the fuse holder is undamaged). Next, the fuse holder must
be pried out using a screwdriver. The starting point is a slot next to the contacts. The
fuse can then be forced out of its mounting and must be replaced with an identical fuse
(see information about the fuse type on the rear panel). The fuse holder will be inserted
against the spring pressure until it locks into place. The use of mended fuses or short

CR mode
CR mode is a special case of sink mode in which the instrument behaves like a constant resistor. Only in this mode, the respective channel keys and display font color in
the home window turns cyan.
In "normal" sink mode, the colors are the same as in source mode: green if the current
flowing into the R&S NGL200 is below the set current and red if the current is limited to
the set value. The only visible indication of sink mode is the change of the sign of the
current readout change to "Minus".
Color illuminated on front panel keys and display
font color of voltage and current in home window
Green Constant voltage mode (CV)
Red Constant current mode (CC)
Cyan Constant resistance mode (CR)
Also, the operating symbol mode (CV, CC or CR) is displayed at the channel status bar
of the respective channel.
4.4 Maintenance
Before cleaning the instrument, ensure that it has been switched off and power cable is
disconnected.
