Introduction

The PCTS pre-compliance harmonics and flicker test system provides a cost effective solution for testing products to EN61000-3-2 harmonics, and EN61000-3-3 Flicker standards during internal product qualification and development stages. Using line AC power from 100 - 240 Vac 50 Hz, the PCTS uses proprietary software algorithms to compensate for line distortion. Hence, test results will be virtually identical to those that will be obtained with a full compliance test system. This ensures that results are consistent and repeatable, regardless of prevailing line conditions.

For flicker analysis, the use of a sophisticated dual channel measurement technique compensates for the lack of the IEC 725 impedance and dynamically calculates the correct flicker results. Therefore, test results of the PCTS are within a few percent of those that will be obtained by a certified full compliance test system. Thus the

PCTS can be used to check EUT’s before submitting them to a test lab or for periodic verification of product compliance in a production environment.

Modular Architecture

The PCTS system utilizes an easily upgradeable modular approach. The signal conditioning unit converts voltage and current into low level signals that are routed to the AC power analyzer card that is installed in the user’s PC. This approach is extremely cost effective, and only requires the user to plug the signal conditioning unit into a wall outlet. The EUT is then plugged into the signal conditioning unit, which can be placed under a printer or a desktop style PC.

50 Hz AC Line Operation

Typical harmonics and Flicker compliance test systems such as the California Instruments CTS series utilize a programmable AC power source. The PCTS however relies on the available

50 Hz AC line power. Note that 60 Hz line power with different voltage levels may cause harmonics spectra to differ substantially. Moreover, 60 Hz power distribution systems also have a lower impedance, affecting Flicker calculations. Thus, it is advised to use a fully IEC compliant CTS Series system under these conditions.

The included PACS signal conditioning unit (Power Analysis and Conditioning System) provides the required signal isolation and scaling for the PC based acquisition system. A high speed sampling system records and processes all relevant data and produces a real-time display of voltage, current and harmonic content.

The elimination of the AC power source and the use of a PC based measurement system greatly reduces the acquisition cost of the PCTS compared to traditional harmonics and flicker test systems.

PCTS Series - IEC 61000-3-2 Harmonics Test

Simple buttons start and stop automated test.

Key EUT electrical parameters are updated continuously.

User selectable test limit margin.

Test start time and test progress are clearly indicated.

Clearly marked Pass (Green) or Fail (Red) indication is active during the entire test run. AC Line distortion is monitored and compensated for in software.

The Windows based graphical user interface (GUI) greatly facilitates the use of the system by the operator. EUT class selection and test time are the only required user inputs. If desired, additional information on the EUT can be entered for incorporation in the test report. The result of each test run is clearly shown using color highlights.

Actual EUT current harmonics versus IEC test limits are displayed in graphical form with a clear indication of which harmonics surpass the IEC limits.

AC Line voltage is monitored in realtime and the PCTS harmonic analysis software automatically compensates for the effect of line distortion on the EUT harmonic currents. This produces

Both Voltage and Current waveforms are shown in real-time. For class A and D test, the special waveshape template (red) is shown.

Bottom graphs show current harmonics against IEC class limits. The user can also view the AC Line voltage harmonics in realtime.

test results which are comparable to those obtained with a fully EN610003-2 compliant test system.

Both IEC 61000-3-2.1998 and the IEC 61000-3-2.2001 Amendment 14 standards are supported by the PCTS software.

PCTS Series - IEC 61000-3-3 Flicker Test

Start and Stop Flicker tests with the click of a button.

Start time, current time and stop time monitoring.

Highest values found during test are continuously shown and updated.

Clear Pass (Green) or Fail (Red) indication leaves no doubt about the test result.

User selectable test time.

In Flicker mode, the PCTS software automatically incorporates the effect of the required IEC 725 reference impedance. This software synthesized impedance method eliminates the need to add a costly impedance to the system and produces comparable test re-

sults. A real-time display of flicker parameters such as Pst, dc, dmax and dt is provided during the test run so EUT’s that fail are immediately apparent to the operator. This eliminates the need to wait for the end of an up to two hour test run to know the outcome of a test.

Select test parameters and data display options.

IEC Test limits can be changed for pre-compliance applications.
