Rohde & Schwarz NGE100A Series Bench Power Supply

Manufacturer: Rohde & Schwarz
Model Number: NGE100
The R&S®NGE100B DC Power supply series consists of robust, high-performance, affordable instruments. They offer high efficiency combined with low ripple plus a variety of comfort functions that are not usually found in this class of power supplies.

High precision source and sink

Due to their high accuracy and fast load recovery time, the R&S®NGL200 power supply series is perfect for challenging applications. Their two-quadrant architecture allows them to function both as a source and a sink to simulate batteries and loads. Their short recovery times enable them to handle fast load changes that occur for example when mobile communications devices switch from sleep mode to transmit mode.

Unique features for better results

Galvanically isolated, floating channels: The Rohde&Schwarz power supply family consists of instruments with up to four channels. The circuitry of each single channel is completely isolated 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 Channels have the same voltage range: Most of the Rohde&Schwarz power supplies offer the same voltage range on all channels. You can select any channel for a specific application. Each channel can be regarded as a separate power supply. Parallel and serial operation:  Because channels are electrically equivalent, they can be combined in serial mode to achieve higher voltages. Up to 128 V can be achieved with the R&S®HMP4040, for instance. In parallel mode, the channels can be bundled for higher current. As an example, up to 40 A can be achieved when all four channels of the R&S®HMP4040 are combined. Constant voltage and constant current modes: Configuring and regulating the output voltage (constant voltage mode) is the standard application for power supplies. However, all Rohde&Schwarz power supplies can also be used in constant current mode, with each channel separately configurable. If the configured current level is exceeded, current limiting ensures that only the configured current can flow. The output voltage is accordingly reduced below the configured value. This prevents damage to the test circuit in the event of a fault. Protection functions to safeguard instrument and DUT: Since even the most experienced user is occasionally distracted, the outputs are protected against overloads and short circuits so that the power supply will not be damaged. Rohde&Schwarz power supplies provide multi-purpose protection functions. Depending on the model, users can separately configure for each channel the: ❙ Maximum current (electronic fuse, overcurrent protection, OCP) ❙ Maximum voltage (overvoltage protection, OVP) ❙ Maximum power (overpower protection, OPP) If such a limit is reached, the affected output channel will be automatically switched off and a message will be displayed. Even the delay time of the electronic fuses can be set. With this functionality, you can adjust the behavior of the power supply so that short current spikes do not trip the electronic fuse. Of course the Rohde&Schwarz power supplies have internal overtemperature protection that switches off the instrument if there is an imminent risk of thermal overload. Tracking and link functions: When using the instrument to supply bipolar circuits, for example, the convenient tracking function lets you vary the voltage on all channels in parallel. The overcurrent protection can be linked to other channels (FuseLink function). It can be configured to switch off all channels when one of the channels reaches its limit value. It can also be configured so that certain channels remain active, for example to power the fan that cools the DUT.
