DSW LEMP GENERATORS TYPE SG LEMP-IEC-DSW

The EMCC DR. RAŠEK pulse generators SG DSW-0.1/4 and SG DSW-0.1/1/2 per IEC 61000-4-12 (EN 61000-4-12, IEC 1000-4-12) generate damped sine-waves with 100 kHz ("Ring Wave") respectively damped oscillatory waves with 100 kHz and 1 MHz frequencies.

The ring wave results from switching in power supply lines or from lightning. The single-event type and the decaying oscillatory waveform are the most significant parameters. This test applies to electrical and electronic equipment supplied by public or private networks.

The damped oscillatory wave appears as a consequence of switching with arcing and has fast rise times and high repetition rates and pulse durations. This test is applicable to electrical and electronic equipment in high voltage and medium voltage stations as well as heavy industry.

Both generators include adjustable pulse amplitudes. In addition the damped sine wave generator offers adjustable output impedance and adjustable phase position. The switching elements are maintenance free semiconductor components. Both units are supplied in a 19" chassis and can be supplied with 16 Amp coupling/decoupling network as an option with short delivery.
