CWG CE5

Surge EMC-tester

The CWG-CE5 is a compact EMC test unit designed for testing electromagnetic immunity against pulsed and conducted interference. Demonstrating such immunity is generally a requirement for compliance with the European EMC directive, a necessary step leading to the CE mark.

The Combination Wave Generator fully compliant to IEC 61000-4-5 and IEEE 587 delivers a standard impulse voltage with waveform 1.2/50 µs and a standard impulse current with waveform 8/20 µs. It is a combined impulse-current-/impulse-voltage generator for high-impedance loads RL > 100W and may be used for surge testing of components and devices, as well as for galvanic coupling of surges to cable shields, shielded enclosures, and cabinets.

The built-in capacitive Coupling-/Decoupling Network allows the superimposition of the combination wave generator output to the mains voltage of the device under test.

Additional accessories allow the testing of immunity against pulsed magnetic fields according to IEC 61000-4-9. An Induction Coil in conjunction with the Combination Wave Generator output is used to simulate pulsed magnetic fields according to IEC 61000-4-9. 

Additional Coupling-/Decoupling Networks covering three-phase power supply lines, DC supply lines, and signal lines are also available, as well as a Capacitive Coupling Clamp for coupling to shielded interconnection lines.

The CWG-CE5 excels by its compact design, simple handling and precise reproducibility of test impulses. It features a microprocessor-controlled user interface and a 7” touch screen unit for ease of use. The microprocessor allows the user to execute either standard test routines or a “user-defined” test sequence. A standard USB port provides the ability to print a summary of the test parameters as well as the results to a USB stick.

The software program CE-REMOTE allows full remote control of the test generator via Ethernet light guide as well as documentation and evaluation of test results, accordingly to the IEC 17025. To record definite impulses, it is equipped with an Impulse Recording Function (IRF).

Moreover all generator functions including the built-in Coupling-/Decoupling Network, maybe computer-controlled via the isolated optical interface.

System configuration

The Multi CE5 and its sub-units are available in different configurations:

It is possible to build all devices in a 19” rack cabinet.
