Immunity test system

The Schaffner Modula is a product line for the simulation of electromagnetic interference effects.

Immunity testing in conformity with international, national and in-house standards is handled with efficiency and operator convenience.

Besides the generation of the classic interference pulses such as Burst and Surge as well as Power Quality simulations, further functions can also be readily incorporated in the system configuration.

The system represents a new yardstick for pulse generators and systems intended for investigating the immunity of products to electromagnetic interference.

When used with the automatic step transformer type INA 6502, technicians are able to set the AC power supply voltage to 0%, 40%, 70% or 80% of UIN, under program control.

The INA 6502 is connected to the Modula system via the system cable and is fully embedded in the configuration management concept, the software control and the report mechanism. It complies with the requirements of EN/IEC 61000-4-11(2004) for voltage dips and under voltages.
