HV - Impulse generator PG 4-641 creates standard voltage and current pulses with wave form 10 / 160 μs. Output voltage is adjustable up to 3600 V, the maximum short circuit current amplitude is 480 A peak. Positive or negative polarity of output voltage can be selected. A built-in voltage divider 1000:1 allows monitoring of the impulse output waveform during testing. The short circuit current wave can be monitored by use of the built-in shunt.
