Description
GSR-12KIS BK-2S DC generator
GSR-12KIS BK-2S is a 12 kW high-output DC generator of the GSR-12KIS family. The former catalogue wording “BK2 Series 2” obscured the actual designation; published product tables use the Cyrillic suffix БК-2С, transliterated here as BK-2S. The complete designation should be retained in enquiries and maintenance records.

Published electrical and mechanical data
The BK-2S execution is listed for 28.5 V DC, 12 kW and 4,000–9,000 rpm. Current references disagree on the load-current column, giving 420 A in one table and 450 A in another; the offered unit passport and nameplate therefore control the exact continuous rating. Published dimensions are 196 × 470 mm and mass is 25.5 kg.
Difference from GSR-12KIS BK
The 25.5 kg mass and 196 × 470 mm envelope distinguish the published BK-2S data from the 20 kg figure listed for GSR-12KIS BK. A shared 12 kW class and speed range do not prove identical mounting, cooling, terminals or protection. No automatic interchangeability is declared between the two executions.
Installation and inspection points
Before fitment, record the exact nameplate, serial number and suffix, then check drive geometry, rotation, flange or support dimensions, high-current terminals, insulation and cooling interfaces. Confirm the regulator and generator-protection devices from the aircraft electrical documentation. Bench limits must come from the BK-2S passport, especially because the published current figures conflict.
Selection and catalogue navigation
The electric-generator reference explains the general conversion principle, while selection remains specific to the aircraft installation. Submit the exact GSR-12KIS BK-2S designation and available passport data when requesting supply. Other products in Generators & Starter-Generators are shown for navigation and system review, not as approved substitutes.
