The OCS 500N6 includes test capabilities for ringwave up to 6kV (as per EN/IEC 61000-4-12) and the damped oscillatory waves at 100 kHz and 1 MHz up to 3 kV (as per EN/IEC 61000-4-18).
The Ringwave is a non-repetitive damped oscillatory transient occurring in low-voltage power, control and signal lines supplied by public and non-public networks. Damped Oscillatory Waves are repetitive transients mainly occurring in power, control and signal cables installed in high voltage and medium voltage stations.
The OCS 500N6 can also be used to perform magnetic field tests as required in EN/IEC 61000-4-10 using a magnetic field coil such as the MS 100N1.

Three In One – The OCS 500N6 combines Ringwave and Damped Oscillatory Waves

The OCS 500N6 is the standalone tester that perfectly complements the EM TEST product range for tests as per EN/IEC 61000-4-x.
Equipped with the Ringwave capability of up to 6 kV it also complies with the Ringwave requirements of the American ANSI/IEEE C62.41 standard.
The two Damped Oscillatory Waves with 100 kHz and 1 MHz frequency reach 3 kV each. The Damped Oscillatory Waves not only comply with EN/IEC 61000-4-18 requirements but also correspond with the requirements to test protective relays and relay systems as per ANSI/IEEE C39.70.
The Damped Oscillatory Waves are also used to generate magnetic fields as per EN/IEC 61000-4-10 into a magnetic field coil (e.g. MS 100N).
The OCS 500N6 comes with a built-in coupling/decoupling network for either single phase or three-phase and is rated for currents of 16 A, 32 A or up to 100 A per line.

The OCS 500N6 can be operated manually from the front panel or by remote via the built-in USB or GPIB interface. Fail inputs allow to control an ongoing test sequence based on the status of the EUT. Monitoring outputs (BNC) are offered for easy signal measurement and verification. Safety features such as interlock and warning lamp control are available.
Pre-programmed Standard Test routines allow highest user convenience. Still the OCS 500N6 offers the Quick Start test routine where parameters can be changed on-line during the test to evaluate the susceptibility level of an individual DUT.

iec.control Software for control and documentation

Outstanding user convenience, clearly structured windows and operation features, EM TEST’s comprehensive standards library along with the flexibility to easily generate user specific test sequences are the main features of iec.control software. The software will be automatically configured in accordance with the connected EM TEST generators. Extensive reporting capabilities help the user to create test reports that meet international requirements.
The iec.control is supported by Windows 7, Windows 8 and Windows 10. Remote control is achieved either via Ethernet or optical interface with USB connector at the PC side.
The iec.control supports various interfaces for the communication to external measuring devices.
