Schlöder CWG surge generators replicate the high-energy transient overvoltages that electrical and electronic equipment experiences during lightning strikes, switching events, and short-circuit conditions. Fully compliant with IEC 61000-4-5, the CWG series delivers up to 4400 V open-circuit voltage and 2200 A short-circuit current, covering the standard 1.2/50 µs voltage and 8/20 µs current waveforms required for compliance testing. For applications requiring higher energy levels or multiple pulse shapes, a modular test system option extends surge capability up to 30 kV / 30 kA. An optional colour touch display with USB and optical interface simplifies operation and enables automated test sequences, while a broad range of coupling/decoupling networks ensures the correct impedance conditions for any line configuration. Built for durability with an excellent price-performance ratio, Schlöder surge generators are a reliable choice for EMC compliance laboratories, power electronics development, and surge protection device qualification.
