Data Sheet user Manual


The generator PG1275E is specially designed for conducted susceptibility / transient tests to voltage surge and spikes of 28 Vdc electric circuits in military vehicles according to MIL-STD 1275E.

The maximum permanent current is 16 A. This value can be extended to 400 A using the optional external diode module DM400. For the spike test, the current limit is given by the external 5 µH LISN. Different versions of LISN are available. The generator can be fully controlled by a computer through a RS232 or USB interface. An automation software is proposed to assist the operator in the measurement of the transient parameters including the energy content of the spike and the surge.
