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).
