The Rohde and Schwarz NGL201 is a single channel DC power supply with an output of 0-20 volts / 60 watts. The maximum current would be dependent on the voltage being used:

• ≤ 6 V: 0 A to 6 A
• > 6 V: 0 A to 3 A

Thanks to their high accuracy and fast load recovery time, the R&S NGL200 power supplies are 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.

The single-channel R&S NGL201 and the two-channel R&S NGL202 deliver up to 60 W of output power per channel. The output channels are floating, galvanically isolated and protected against overload and short circuits.

Ideal for use in labs and test systems

Tailored for use in labs and system racks

The R&S NGL200 power supplies are the right choice for challenging applications. They are used in R&S labs and integrated into production test systems.

The power supplies can be installed in 19" racks using the R&S HZN96 rack adapter. Connectors on the rear panel and a compact design are important criteria for use in test systems.

Sense function for lead resistance compensation

There is often a significant voltage drop over the supply leads, especially in applications with high current consumption. Since power supplies usually maintain a constant output voltage, the voltage on the DUT will be lower than the voltage displayed on the power supply. The sense function compensates for this voltage drop over the supply leads. The voltage actually present at the load is measured by an additional pair of sense lines, and this value is used to regulate the voltage directly at the load.

The connectors for the sense lines are located on the rear panel. The R&S NGL201 also has sense line connectors on the front panel.
 
Front and rear connectors

The safety sockets on the front panel of the R&S NGL200 power supplies are designed for 4 mm banana plugs. Additional connections for all channels (including sense lines) are provided on the rear panel to simplify use in rack systems.

Digital inputs and outputs are optionally available. They can be used as trigger, inhibit and fault functions. One more connection is configurable. The hardware of the R&S NGL-K103 option is preinstalled. The function can be activated using a keycode (to be ordered separately).

All connections are also provided on the rear panel (shown here: R&S NGL202).
 

Full remote capabilities

For use in test systems, the R&S NGL200 power supply series can be remotely controlled. The following interfaces are available.

USB and LAN

USB and LAN (Ethernet) interfaces are installed as standard. All supply parameters can be remotely controlled via these interfaces.

Wireless LAN (R&S NGL-K102 option)

As an alternative, the R&S NGL200 power supplies can be remotely controlled via the WLAN interface. The WLAN module, which is activated by keycode (to be ordered separately), supports CLIENT mode, which means that the power supplies automatically connect to a network. The power supplies are operated via a web browser.
Note: The WLAN function is not available in all regions due to country-specific regulations.

GPIB interface (R&S NGL-B105 option)

The R&S NGL-B105 interface with a GPIB (IEEE-488) port is also available as an option.
