The Schaffner / Teseq NSG560 ms Surge Generator has been designed to simulate high current conditions that cause voltage spikes/pulses on a supply that can have an energy content of several thousand Joules. It simulates the effects of over-voltage originated by short circuits cleared by fuse operation. The pulse is shaped internally in a load-dependent manner in order to deliver the maximum possible energy to the device under test while, at the same time, avoiding any overload. Besides the pulse widths of 0.3 ms and 1.3 ms specified in the standard, the user also has the opportunity to set a number of other half-value widths. The phase angle for injection of the pulse into the mains supply is not only calibrated at 90° but is also infinitely variable between 5° and 100°. This feature is especially important for analytical measurements in development laboratories. An electrically isolated voltage monitor output is provided for recording the measurements taken.
