Three channel DC power supply

• 32V/3A per channel
• Can be run in series or parallel
• Both channels are galvanically separately and electrically equivalent

All channels galvanically isolated and earth-free

The circuitry 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.

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 channels 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.

Color-coding of operating conditions

All operating conditions are shown clearly on the 3.5"QVGA display (320 × 240 pixel), including the output power and the status of any protective functions. Colors indicate the different operating conditions:

• Active 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 yellow. Whenever a channel is in the setting mode, the display color changes to blue

Protection functions to safeguard instrument and DUT

Multi-purpose protection functions are not standard in power supplies in the basic class. Here again, the R&S NGE100 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)

Tailored to be used in education, labs and system racks

Power supplies in the basic class offer the functionality you need in daily work - and with the R&S NGE100 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 affordable 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 NGE100 power supply series fulfills all these requirements.

Front connectors with 4 mm screw-type sockets
The output connectors on the front of the R&S NGE100 power supplies can hold 4 mm banana plugs or they can clamp stripped cables as very often seen in educational applications. The design of the connectors is robust enough to survive generations of students.

USB interface (virtual COM port and TMC class)
Via the USB interface, the instrument can be controlled from external PCs.

LAN interface (LXI) with integrated web server (R&S NGE-K101 option)

In addition to the standard USB connector, the R&S NGE100 power supplies offer an optional Ethernet interface, which can be activated by the customer using a key code that has to be ordered separately. This option allows the user to remotely control all instrument parameters. A fixed IP address can be used, or, alternatively, DHCP function might be used to allocate dynamic IP addresses. The Ethernet function offers a web server that can be used by standard web browsers (i.e. Internet Explorer).

Digital trigger in/out (4-bit) on the rear (R&S NGE-K103 option)

Another option for the R&S NGE100 power supply series is a set of a 4-bit digital in/out interfaces that can be individually used as trigger inputs or outputs. Similar to the other options, the hardware of the R&S NGE-K103 option is already installed, the functionality is activated with a key code.
