High Accuracy Power Analyzer for a wide range of Applications

The PPA4500 features high-speed FPGA/DSP sampling techniques and N4L’s highly respected "Planar Shunt” Technology, the PPA4500 is the result of over 12 years of development. The PPA4500 replaces the outgoing PPA2500 and PPA2600 models, with improved accuracy, color TFT, front USB port and faster processing. The PPA4500 is a significant leap forward in both accuracy and functionality. The PPA4500 is well suited to transformer loss testing, PWM inverter drive efficiency testing, standby power testing to IEC62301/EN50564 and many more challenging applications.

The PPA4500 exhibits the ability to measure fundamental frequencies up to 2MHz, as well as up to 100 Harmonics with the same 2MHz upper-frequency limit. PWM Motor drive mode enables the engineer to rapidly set up the instrument to measure complex harmonically distorted waveforms, sophisticated signal processing algorithms facilitate high sample rate (2Ms/s) true wideband (2Mhz) analysis of PWM signals. The PPA4500 Utilizes parallel digital filtering for fundamental frequency synchronization without affecting the bandwidth of the measured data.

All PPA5500 units are supplied with UKAS ISO17025 certification as standard, this is performed at N4L in the UK in our accredited ISO17025 Laboratory.

ISO17025 Calibration and Verification

Every PPA4500 Power Analyzer supplied by N4L is provided with both a UKAS Accredited calibration certificate up to 850Hz, as well as a UKAS Traceable calibration certificate up to 1MHz. N4L has developed a number of bespoke power calibrators in order to verify the accuracy of every power analyzer supplied over its entire frequency range, this is surprisingly uncommon within the instrumentation industry. Furthermore, the development of an ISO17025 (UKAS) accredited Closed Loop Calorimeter in partnership with Oxford University (UK) has verified the performance of the N4L custom designed power calibration rigs with a very low uncertainty level, providing absolute confidence that the wideband performance of all N4L power analyzers is market-leading.


Calibration Options

1. Standard Re-calibration - Included with new instruments – Included with RMA Calibration
Wideband calibration (DC-2MHz) with optimization of measurements on all ranges over the complete instrument bandwidth. Traceable to UKAS but not ‘accredited’.
2. UKAS (ISO17025) Calibration – Included with new instruments – Optional with RMA Calibration
UKAS Accredited calibration of Voltage, Current, Phase (PF) and Power on all ranges from 55-850Hz.
This option includes the option 1 calibration.
In addition to the calibration certificates, the PPA will be fitted with a UKAS calibration label.
3. System Calibration – Standard - Optional with new instruments or RMA calibration
UKAS accredited calibration of a PPA together with an external sensor.
This option is separate to option 1 which must also be ordered when system calibrating.
Note: This is an end-to-end calibration of the PPA+sensor ‘system’ at an N4L defined test point or points and does not include UKAS calibration of the PPA alone (option 2).

4. System Calibration – Non-Standard - Optional with new instruments or RMA calibration
The same as Option 3 but applied at customer requested test points. This will be UKAS only for frequencies between 16-850Hz.

5. UKAS IEC61000 H+F Calibration - Optional with new instruments or RMA calibration
UKAS accredited calibration of PPA55x1 series units that includes all prevailing type test protocols for fully compliant Harmonic and Flicker testing.
This option includes option 1 and option 2 calibration.
6. PPA55xx-TE Calibration – Included with PPA-TE order – Optional with RMA Calibration
Custom UKAS calibration that includes a series of low power factor tests down to 0.01 PF over the frequency range of 16-450Hz.
This option includes the option 1 calibration.
7. UKAS calorimeter power calibration – Optional with new instruments or RMA calibration
UKAS accredited power calibration via calorimetry. Available at customer requested frequency(s) and with sinusoidal or harmonically distorted wave shapes within a frequency range of 45Hz to 2MHz.
This option includes options 1 and 2.
