GSR-12KIS BK
DC Generator
Description
GSR-12KIS BK DC generator
GSR-12KIS BK is a 12 kW high-output DC generator of the GSR-12KIS family. Published electrical-power-system tables identify the BK execution as a brushless DC machine rated for a 28.5 V aircraft network. The complete suffix is important: GSR-12KIS, GSR-12KIS BK and GSR-12KIS BK-2S must not be treated as one undifferentiated part number.

Electrical ratings of GSR-12KIS BK
The consistently published values for GSR-12KIS BK are 12 kW, 28.5 V, approximately 420 A and an operating-speed range of 4,000–9,000 rpm. A published mass of 20 kg belongs to the BK execution. These ratings place the unit in the high-current primary DC system class; the aircraft regulator, feeder protection, cabling and cooling arrangement must correspond to the approved installation.
Execution differences within the family
The closely named BK-2S execution is listed separately with a 25.5 kg mass and a 196 × 470 mm envelope, while published current tables for BK-2S differ between 420 and 450 A. Those dimensions and the higher current figure are not copied to this GSR-12KIS BK card. The base GSR-12KIS also has its own cooling and installation data.
Installation and incoming inspection
Identification starts with the complete nameplate, suffix and serial data. Before installation, verify the drive connection, direction of rotation, mounting points, high-current terminals, insulation, cooling connections and the approved voltage-regulation and protection equipment. A bench test must follow the component manual for the exact BK execution rather than settings taken from another family member.
Selection and ordering
The operating principle of an electric generator does not establish interchangeability between executions. An enquiry for GSR-12KIS BK should include a nameplate photograph, aircraft or engine context, required documentation and the removed-unit reference. Related DC machines are listed in Generators & Starter-Generators; cross-sells are navigation links, not replacement approvals.
