Manual

Using the NSG 200 series of instruments, different types of mains interference can be simulated.
 

  • Mainframe - NSG 200D contains line switches, line filter, fuses and other elements
  • Plug-In - NSG 203A simulates short variations and interruptions in line voltage

  • Operation with line voltage
    • Max rated voltage: 120V / 60 c/s
    • Max rated current: 16A
  • Operation with external voltage
    • Max rated voltage (=): 400 volts
    • Max rated voltage (~): 250 volts (RMS)
    • Max rated current (50/60 c/s and dc): 16A
    • Max rated current (400 c/s): 6A



NSG 203A Plug-In
 

NSG 203A can be used to simulate short variations in line voltage or line failures. For simulating a variation from a high voltage to an abnormally low voltage (for example, if one voltage is 150V, the other 280V), two external variable voltage transformers are needed. Cables to these transformers with corresponding connectors are available as NSG 322 (one transformer) and NSG 323 (two transformers).
 

Using the NSG 203A equipment can be tested to the following test specifications
 

  • Mil Std 704 A, Mil Std E 4158 (Table II - Fig. 1)
  • BS 4509 / 4525, CEE (Sekr. 229) UK 121, EEC Com. (78) 766 final
  • VDE 0160 8 and British specification CE GB - EES (1970)
