The Fluke N4K 3PP42IB Norma 4000 Three-Phase Precision Power Analyzer with PP42 Power Phase Input Modules (x3), Current Binding Post and IEEE488/ Ethernet Interface offers easy and straight-forward operation, which is ideal for field testing.
N4K 3PP42IB accurately measures current and voltage and calculates active, reactive and apparent power; it calculates other derived values from these high-precision measurements.
Accuracy is not affected by either the waveform shape or frequency over a wide range. Phase shift accuracy is maintained due to the input channel design. Harmonics are calculated up to half of the sampling rate.
The DSO function represents measured input parameters as waveforms. Voltage and current can be measured directly via the instrument's integrated voltage dividers and shunts. It is also possible to connect external voltage dividers as well as shunts or current probes for specific applications. Options such as additional interfaces, analogue inputs and outputs are also available. The analyzer firmware can be updated via the standard RS232 interface.
High Precision Measurements
N4K 3PP42IB is designed to measure signals in a wide frequency range, from DC to MHz. The input stages are DC coupled and designed to handle high rise time signals. A zero and offset calibration against a stable voltage reference runs automatically over short time periods to stabilize accuracy.
All voltage and current channels are separated by a unique technology of barriers for high channel isolation and common mode rejection. This makes this power analyzers suitable for special applications, such as switching waveforms present on variable frequency drives or high efficiency lighting loads.
The exceptionally high processing power enables precise measurements without gapping, ensuring good results even with rapidly changing signals.
N4K 3PP42IB maintains high performance and reliable accuracy within the industry's longest recommended recalibration interval of two years. This long interval reduces downtime and saves service costs.
There are four different measuring channels available for each N4K 3PP42IB. For the highest level of flexibility and simplicity, you can choose from a variety of standard configurations. This enables users to select the power analyzer best suited to their application's power measurement requirements. Each power phase module differs in basic accuracy, current measuring range, sampling frequency, and bandwidth.
The input modules can handle up to 10A or 20A directly or measure current via wideband precision shunts. The available range of shunts enables measurements up to 1500A and can be used in conjunction with all of the available input modules.
Powerful NormaView PC Software
The Fluke NormaView software improves operation efficiency of the analyzers by enabling instrument setup settings to be saved and stored along with the measurement data. Instrument setups can be used for particular measurement tasks. Settings can be easily uploaded to the instrument with just a few mouse clicks. The software also enables quick and easy data download, analysis and report writing.
Modular Power Phases
N4K 3PP42IB can be equipped with up to three power phases. Users can select the type of power phase best suited for their application from a variety of optional power phases. Specifications vary depending on the model of the power phase.
Each modular plug-in power phase consists of a voltage and a current measurement channel. Each measuring channel is available for each basic unit. However, only one kind of channel can be used per unit.
Optional Process Interface
The optional process interface can be used with N4K 3PP42IB. It provides the simultaneous recording of torque (M), speed (N) and mechanical power (Pm), for up to four motors. Each of the eight inputs is switchable between analog (voltage) or digital (frequency) input. This interface provides synchronous capture at a sample rate of 34 kHz. The interface also provides four analog outputs, which are updated after every average interval. By inputting the additional analog and digital values it is possible to fully evaluate electrical and mechanical efficiency in real time.
