TR-100

TR-100 System Overview

The TR-100 is an aircraft adjustable transformer designed for stepwise regulation of AC voltage within onboard electrical systems. The unit is used as part of power distribution systems requiring controlled voltage levels.

TR-100 Regulation Function

The transformer provides discrete adjustment of output voltage through predefined steps, ensuring stable power supply to connected equipment. It enables precise voltage control for sensitive onboard consumers.

TR-100 Aircraft Application

The unit is applied in aviation systems, including heavy transport helicopters such as Mi-26, where it is used to supply electrical equipment requiring regulated AC voltage.

TR-100 System Integration

The transformer operates within onboard AC power systems and supports continuous operation under standard aviation electrical parameters. It is available in different modifications, including dual-channel and remotely controlled versions. The product is also known under alternative designation TR-100 and ТР-100.
