SG61000-5 Surge Generator

Surge Generators are intended for testing Surge Protective Devices(SPDs), Varistors, and the like, according to IEC61000-4-5，EN61000-4-5 etc. The generators are able to deliver two types of surge waveforms—8/20μs current wave and 1.2/50μs combination wave.

Each generator has three Pulse Forming Networks (PFNs)—PFN/A,PFN/B, and PFN/C that will output 8/20μs±20% currents, 1.2/50μs±20% voltage, and 1.2/50-8/20 combination wave respectively, so that a wide range of 8/20-surge currents can be obtained.  

The SG-Series Generators are special test equipments of high voltage ,high current and high energy, therefore absolute safety of both people and equipment will be the first consideration. The significant safety measures adopted are as below:

1) The chassis and all dead metal parts of the generator reliably earthed.

2) The interlockers will immediately break the power and discharge the capacitors of PFNs during the period of charging in case of either any opening of the doors in the generator and test chamber or power supply accidentally OFF.

3) The “ Emergent Discharge” button allows immediate breaking the power and discharging the capacitors of PFNs through a special resistor at any time.

4) A special protective device allows discharging of the generator in case that the tested unit being connected not properly or being short-circuited.
