NSG600 Datasheet
The Schaffner NSG600 Interference Simulator System provides for the simulation of the most varied transient conditions which occur in AC and DC mains, but also has facilities to permit the application of transients without supply voltage. The system consists of a main frame and various plugin units which generate the specific disturbances.
Teseq NSG600 Features
  • Main frame unit with centralized power supply and control for 1 to 4 plug-in units
  • Microprocessor controlled function keys and LCD display
  • Connection to the unit under test and pulse output
  • RS 232-C interface for computerized remote control
