SFT Electrical Fast Transient / Burst Simulators
Schlöder EFT/burst generators test the immunity of electronic and electrical equipment against fast transient voltage spikes with high repetition rates and short rise times. Compliant with IEC 61000-4-4, models cover frequencies from 125 kHz up to 2 MHz — well beyond standard requirements — with integrated coupling networks. Built for durability and an excellent price-performance ratio, they deliver reliable, repeatable burst immunity testing.

Schlöder SFT burst generators simulate the fast transient voltage spikes and burst disturbances that electronic equipment encounters in real-world electrical environments. Compliant with IEC 61000-4-4, the SFT series covers repetition frequencies from 125 kHz up to 2 MHz — well beyond standard requirements — ensuring thorough immunity characterisation of power lines, control lines, and signal cables. Integrated coupling networks simplify test setup, while test voltages up to 5 kV and a robust mechanical design make the SFT series suitable for both routine compliance testing and demanding R&D environments. An optional colour touch display provides an intuitive operator interface with USB and optional optical interface for remote control and data logging. A broad accessory range — including CDNs, capacitive coupling clamps, and calibration attenuators — allows the SFT series to be adapted to virtually any EFT/burst test requirement under IEC 61000-4-4.
