These are low voltage high current A.C. power supplies, output isolated from input. Output may be single range or multi range involving series parallel connections of secondary windings of loading transformer. The primary current injection sets are useful for testing current operated devices such as relays, current transformers etc. This is an asset for electrical testing laboratories, power houses, sub-stations etc. Portable models can be easily taken to the field for on site testing.
