• Includes NGE103B three channel DC supply
• 32V/3A per channel
• Includes several software options - NGE-K101, K102 and K103

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.

All basic functions of the R&S NGE100 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 multi-purpose protection functions. The operating conditions of all channels are displayed on the screen simultaneously. Active channels are indicated by the illuminated channel key. 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.

To safeguard the instrument and the device under test (DUT), the R&S NGE100 power supplies provide a variety of protection functions. For each channel, users can separately set the maximum current (electronic fuse, over-current protection, OCP), the maximum voltage (over-voltage protection, OVP) or the maximum power (overpower protection, OPP). If such a limit is reached, the affected output channel will be switched off. Over-temperature protection (OTP) prevents overheating of the instrument

In industrial applications, power supplies are often installed in 19" racks. The R&S HZC95 rackmount kit allows the power supplies to be mounted in racks, including in combination with R&S HMC test instruments. The R&S NGE100 power supplies can be remotely controlled via USB or optionally via Ethernet or even via wireless LAN.

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.
