About the AvK DSG series (from the AvK DSG product brochure – series standard, not checked on these units)

• Self-regulating, brushless synchronous alternator with damper cage, self-excitation via permanent magnets in the exciter
• Voltage regulator COSIMAT N+ (standard from DSG 74), in a separate terminal box on DSG 114–144; static voltage tolerance ±0.5 to ±1 %
• Equipped as standard for parallel operation (voltage droop current transformer)
• Overload: 1.5 x rated current for 30 s, 1.1 x for 1 h within 6 h, approx. 1.8 x for approx. 10 s; sustained short-circuit current 2.5–4 x rated current for 3 s
• DSG 114–144: feet integrated in the end shields, both end shields bolted to the stator housing
