Welcome to R&S NGP800
2 Welcome to R&S NGP800
The two or four-channel power supply series are based on a primary switched-mode
regulator with power factor correction. This concept allows the instrument to achieve
highest accuracy and lowest residual ripple.
The R&S NGP800 power supply series feature galvanically isolated, overload and
short-circuit proof outputs. The outputs can be connected in parallel and serial to achieve higher currents or voltages.
Multi-purpose protection functions, such as overcurrent protection (OCP), overvoltage
protection (OVP) and overpower protection (OPP) can be set separately for each channel. If the set limit is reached, the affected output channel is automatically turned off
and an indicator icon ( , , ) flashes on the display. The overcurrent protection can
also be linked to the other channels. If the current exceeds the limit on the affected
channel, all linked channels will be switched off.
The R&S NGP800 power supply series are also protected from overheating. Each
channel is equipped with a temperature sensor that monitors the channel operating
temperature for controlling the fan speed and overtemperature protection. If the safe
limit is exceeded, the output of the affected channel is switched off. The channel must
cool down to a defined threshold before the output can be switched on again. Operations of the other channels are not affected. Also, the actual operating speed of the
fans is monitored. If a fan is not running, e.g. rotor locked condition, all the outputs will
be switched off to prevent overheating.
The R&S QuickArb function allows freely definable voltage and current sequences with
a timeframe as short as 1 ms, e.g. to simulate different charging conditions of a battery.
The voltage and current points can also be grouped in different blocks which can be
sequenced and repeated independently to achieve a flexible arbitrary function generation.
With the R&S EasyRamp function, the R&S NGP800 power supply provides the operating condition to ramp up the supply voltage within a defined timeframe up to 10 s with
1 ms step size and it can be set independently for each channel. Furthermore, the
channels can be sequenced to ramp up the voltage output applied at different times.
With different slew rates and delays between channel outputs, it is easy to test multivoltage systems reliability. For the four-channel power supplies, the outputs can also
be arranged into two independent subgroups.
The analog input and digital I/O interfaces at the rear panel can be activated with an
option key. The analog input allows you to control the output directly using voltage signals (0 V to 5 V analog input corresponds to 0 to Vmax or Imax) and can be set independently for each channel. The analog inputs are galvanically isolated from the channel outputs, making the connection simpler. The digital I/O provides an 8-bit control
port for various control functions. Each pin can be configured as input or output port, to
control any output channel, trigger an event, e.g. start arbitrary or to indicate various
conditions, e.g. over current protections.
The R&S NGP800 power supplies are equipped with a color 800 x 480 5 " TFT LCD
touch screen and a USB and LAN interfaces to control the instrument remotely. With
wireless LAN (WLAN) option, network connection can also be established wirelessly.

3.2 Ambient Conditions
The allowed operating temperature ranges from +5 °C to +40 °C (pollution category 2).
The maximum relative humidity (without condensation) is at 80 %.
During storage and transport, the temperature must be between -20 °C and +70 °C. In
case of condensation during transportation or storage, the instrument requires approximately two hours to dry and reach the appropriate temperature prior to operation. The
instrument is designed for use in a clean and dry indoor environment. Do not operate
with high dust and humidity levels, if danger of explosion exists or with aggressive
chemical agents.
Any operating position may be used; however adequate air circulation must be maintained. For continuous operation, a horizontal or inclined position (integrated stand) is
preferable.
Specifications with tolerance data apply after a warm-up period of at least 30 minutes
at a temperature of 23 °C (tolerance -3 °C / + 7 °C).
The heat produced inside the instrument is guided to the exterior via temperature-controlled fan. Each channel has multiple temperature sensors which check the heat generation in the instrument and control the fan speed.
It is necessary to ensure that there is sufficient space around the instrument sides for
heat exchange. If the temperature inside the instrument increases more than the
