► In the parallel operating mode, channels can be bundled to achieve higher currents.
► In the serial operating mode, channels can be combined for higher output voltages.

Modulation inputs

► The R&S HM8143 provides two modulation inputs on the rear, so it can be used as a power amplifier with a frequency range from DC to 20 kHz. Applications include testing of AC motors, relays, etc.

Electronic fuse

► In order to provide even better protection than current limiting, the R&S HM8143 offers the feature of an electronic fuse. As soon as the current limit is reached, all outputs are simultaneously disabled.

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.

High-speed data acquisition and convenient battery simulation widen the range of applications.

Battery Simulator Function

When battery-operated devices have to be optimized for lifecycle, the discharging behavior of the used battery type needs to be considered.

The battery simulator function makes it possible to simulate the real battery output performance. Testing can be based on a selected battery model, while battery capacity, SoC and Voc can be set to any state to test the device under specific circumstances

Easy Operation

The high-resolution capacitive touchscreen is the central operating element for the R&S NGM200 power supplies. Icons clearly show the status of set protection or special functions.

When the power supply is in constant voltage mode, the numbers and the keys light up green. Red is used for constant current mode. The Output key lights up blue to indicate that the channels are switched on (active).

Readings with up to 6½ digit resolution

With a resolution of up to 6½ digits when measuring voltage, current and power, the R&S NGM200 power supplies are perfect for measurements on devices that have low power consumption in standby mode and high current in full load operation.

Two voltage measurement ranges and four current measurement ranges provide a high accuracy and resolutions down to 1 µV/10 nA

Boost your efficiency with quadcore power

The R&S NGP800 DC power supply series, comprising five models with 400 W or 800 W, provides maximum power at a variety of operating points. The two or four 200 W outputs can each supply up to 64 V or up to 20 A. Electrically equivalent and galvanically isolated outputs can be wired in series or parallel for up to 250 V or 80 A.

5″ high-resolution touch display

The large high-resolution touch display makes operation easy. Quickly navigate through the menus to access all functions and settings. Enter values much faster using the virtual keyboard instead of turning the knob.
The home screen gives you a clear overview of all your channels. Each channel can be selected for a more detailed view with a wide variety of additional information, such as statistics and icons indicating the status of set protection or special functions.

Parallel and serial operation

If your application requires more voltage or current, simply connect the outputs in series or parallel and get up to 250 V (R&S NGP824) or 80 A (R&S NGP804) – now you have the flexibility you always asked for.
Using the tracking function,voltage and current are adjusted on all selected channels simultaneously

Ramp function (EasyRamp)

To control inrush currents, some test setups require a continuously rising supply voltage instead of a rapid jump. Increase the output voltage continuously within a timeframe of 10 ms to 60 s with the EasyRamp function.

Arbitrary function (QuickArb)

Emulate the normal behaviors of your power subsystems early in the design process and simulate power problems for DUT design verification.
The QuickArb function lets you generate voltage and current sequences that vary over time with dwell times down to 1 ms. Load up to eight subgroup files into one sequence to create complex patterns

Remote sensing

Improve your voltage regulation using remote sensing, regulating the output voltage directly at the DUT input terminals instead of the power supply’s output terminals.
The four-wire remote sensing compensates for voltage drops in the supply leads, especially in applications with high currents. The R&S NGP800 power supplies provide sense connections for each output at both the front and rear
terminals.

Data logging

Logging data is key to long- term monitoring, reviewing test setups and repeating test conditions when analyzing power behaviors or optimizing power consumption.
The R&S NGP800 power supplies simultaneously log voltage and current measurements over time on all outputs.
You can easily export the timestamped data as a .CSV file for reports and documentation.

Built-in measurements

The built-in measurements reduce the need for an external multimeter and simplify the setup. The separate voltage and current meters on each output give a resolution of 1 mV and 0.5 mA over the full output range of 64 V and 20 A, respectively.
The integrated statistics show the min./max. and average values for power, voltage and current as well as an energy count.

Protection functions

Protecting your DUT is crucial in limit testing. The R&S NGP800 power supplies include overcurrent protection (OCP), overvoltage protection (OVP) and overpower protection (OPP).
The internal overtemperature protection (OTP) switches the power supply off if a thermal overload is imminent.
You can set the maximum current, voltage and power separately for each channel. If an active protection function trips, you are alerted by a beeping sound and the corresponding symbol flashing on the status bar.
