CALIFORNIA Instruments' MXCTS System offers comprehensive testing to harmonics emission standards IEC 61000-3-12 and IEC 61000-3-2; flicker measurement standards IEC 61000-3-11/3, and immunity testing including IEC 61000-4-14 (voltage dips), IEC 61000-4-17 (dc ripple) and IEC 61000-4-28 (frequency variations).

The MXCTS, available from Westek Electronics , offers pre-compliance testing to IEC 61000-4-11 (voltage dips and variations), IEC 61000-4-27 (three-phase unbalance) and IEC 61000-4-29 (dc voltage dips and interruptions.

In addition the MXCTS offers testing for harmonics and inter-harmonics immunity testing.

The MXCTS system is modular in construction consisting of a power source (MX45-3Pi) with up to 65 amps rms per phase output, and the analyser system comprised of a PC for data acquisition, harmonics analyser, and flicker reference impedance.

Direct PC bus access permits high speed data transfer with direct memory access in accordance with the requirements of IEC 61000-4-7 and IEC 868.

The MXCTS software for harmonics and flicker testing provides real-time, full colour display updates and continuous Pass/Fail monitoring and automatic calculation of maximum permissible system impedance based on flicker tests with the reference impedance which is a part of the MXCTS system.

The Windows-based operation software provides for simple test set-up procedures, data analysis and MS Word test reports.
