IJ-2, IJ-2A Siemens-Allis Accu-Stat control repair

Siemen’s first fully solid state control, it turned out to be one of the best on the market. For this reason, there remains a number of these in service across the country.

The difference between the IJ-2 and IJ-2A is the presence of a tapped input transformer in the sensing circuit on the ‘2A. This allows the lineman to adjust for differing ratios in the PT’s inside different regulators, allowing a true readout of voltage setting without having to note multipliers.

Of course, we offer fast, expert service on these.
