Multi CE5

Compact EMC-tester

The Multi-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.

In its basic configuration, the Multi CE5 includes an Electrical Fast Transient Generator (EFTG-CE5), a Combination Wave Generator (CWG-CE5) and a Coupling-/Decoupling Network (CDN) for single-phase power supply lines.

The Electrical Fast Transient Generator fully compliant to IEC 61000-4-4 delivers fast transient pulses with waveform 5/50 ns and a maximum burst frequency of 1 MHz. It is used for immunity testing of electronic systems and devices. The four standard IEC 61000-4-4 test levels may be easily selected by push button or all parameters may be adjusted individually.

The CWG-CE5 hybrid generator, fully compliant to IEC 61000-4-5 and IEEE 587, is a combined impulse current/ impulse voltage generator that generates a standard impulse with a voltage waveform of 1.2/50µs at high-impedance load (output, RL > 100Ω) and a standard impulse with a current waveform of 8/20µs at short-circuited output. It 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 superimposition of the combination wave generator output to the mains voltage of the device under test.

The simulation of voltage dips and voltage variations acc. to IEC 61000-4-11 can be included as an option. Additional accessories allow the testing of immunity against both pulsed and power frequency magnetic fields according to IEC 61000-4-8 and IEC 61000-4-9.

Optionally the Multi-CE5 can include a triggerable power-supply-switch which allows the simulation of the voltage dips as specified in the standard IEC 61000-4-11. The variation of the power supply voltage is controlled by the use of an external motor driven variac. The control of the external power source is included in the mainframe.

An Induction Coil in conjunction with the Combination Wave Generator output is used to simulate pulsed magnetic fields according to IEC 61000-4-9. Combined with the external power source, the Induction Coil can be used to simulate power-frequency magnetic fields according to IEC 61000-4-8.

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 Multi-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:

Typical configurations:

Multi CE5 1 + CDN 5416

for 3-phase testing (picture on the right side)

Multi CE5 2 + VPS 250-16

for testing surge, burst, power fail, voltage dips and variation

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