Lamar GC07 CONTROLLER

The **Lamar GC07 Generator Control Unit** (P/N **GC07**) is a 28 V aircraft electrical control unit designed to regulate and monitor compatible DC generator systems. The GC07 incorporates pulse-width modulation (PWM) technology to maintain regulated generator output across varying electrical loads, temperatures and generator operating speeds. The unit provides adjustable voltage regulation, generator line contactor control, reverse current protection and overvoltage protection to support aircraft electrical system operation. Additional functions include generator-off warning indication and load meter drive, allowing monitoring of generator operating conditions. The GC07 is associated with **Air Tractor P/N 61737-1** and supports applicable aircraft generator control system maintenance and replacement applications. --- ## Applications Suitable for applicable: - **Air Tractor Aircraft** – Generator control applications referencing P/N 61737-1 - **28 V Aircraft Generator Systems** – Generator voltage regulation and control - **Aircraft Electrical System Protection** – Overvoltage and reverse current protection - **Generator Line Contactor Control** – Management of generator connection to the aircraft electrical system - **Aircraft Generator Monitoring** – Generator-off warning and load meter functions - **Aircraft Electrical System Maintenance** – Replacement and servicing of compatible generator control units Aircraft model, electrical system configuration and part-number eligibility must be confirmed against the applicable aircraft maintenance documentation. --- ## Why CJ Aerospace?
