USL(M) series - low voltage synchronous generators
Generators of USL(M) series are generators of SIEMENS family. The brushless constant-voltage synchronous alternators are of the self-excited type with an electronic voltage regulator integrated in the excitation unit. They are used as main and standby units in land-based power installations and for ship's electrical systems and can be driven by internal combustion engines or gas, steam and water turbines and electric motors.
