Generator control unit
Description
BRZU115VO-3S regulation, protection and control unit
BRZU115VO-3S is an aircraft electrical control unit used in an AC power-generation channel. It combines voltage regulation, protective supervision and generator-control functions in one assembly. The unit does not generate electrical power itself; it works with the generator, excitation circuit, switching equipment and onboard network. Its exact operating law is determined by the execution identified by the complete suffix, so closely related BRZU units must be treated as separate products until documentation confirms compatibility.

Operating role of BRZU115VO-3S
BRZU115VO-3S is intended for a three-phase AC generation channel of constant or variable frequency using a brushless generator with an integral three-phase pilot exciter and accessible neutrals. Manufacturer catalogue data states a 24.0–29.4 V DC supply and a three-phase 22–29 V AC supply at 800 ±40 Hz. Listed current consumption is not more than 3.4 A from the DC source and not more than 0.04 A from the 400 Hz AC source.
Integration with aircraft electrical equipment
The unit belongs to the electronic control equipment of the aircraft electrical system. Reliable operation depends on correct DC supply, generator or exciter inputs, serviceable wiring and the specified contactor or protection circuits. During troubleshooting, the block should be checked as part of the complete generation channel rather than replaced solely because the bus voltage is abnormal. Bench testing and adjustment require the approved passport or repair documentation for this exact execution.
Aircraft-system application
The unit is used in aircraft generation systems configured for the matching brushless generator and exciter interface. The external reference to aircraft is provided for aircraft context; it is not an interchangeability statement. Installation on a particular airframe depends on its modification, generator set and approved electrical-system configuration.
Identification and ordering
Confirm the full BRZU115VO-3S marking, Cyrillic designation, series or suffix, connector arrangement and passport before ordering. Similar BRZU115V, BRZU115VA and BRZU115VO names can describe different regulation channels, supply interfaces or protection settings. An enquiry should include the aircraft type, installed generator or system designation, required condition and available data-plate photo. Replacement is accepted only after comparison with the aircraft illustrated-parts catalogue and maintenance documentation.
