1256D-3Y

The 1256D-3Y is a 3-phase manually operated POWERSTAT Variable Transformer with rugged mechanical construction. This POWERSTAT Transformer feature POWERKOTE coils for longer life, increased ratings, greater overload capacities and better resistance to fungus, salt spray and other contaminating atmospheres. The commutator of the new POWERKOTE coil is embedded in a high temperature material which holds the windings in place, even under severe overloads. As a result, POWERSTAT variable transformer with POWERKOTE coils provide higher output ratings than ordinary variable transformers. To permit maximum utilization of POWERSTAT variable transformer, output ratings are given for both constant current and constant impedance loads.
