PMK-14

PMK-14 System Overview

The PMK-14 is an aircraft electromechanical program mechanism designed as part of electrical power system protection equipment. The unit functions as a control and protection device integrated into onboard generator protection systems.

PMK-14 Control Function

The mechanism provides automatic disconnection of the AC generator from the onboard electrical network in case of faults such as internal short circuits or network failures, ensuring protection of power supply systems and prevention of equipment damage.

PMK-14 Aircraft Application

The unit is primarily used on helicopters equipped with AC power generation systems, including Mi-8 family helicopters, where it serves as a standard element of generator protection and control systems.

PMK-14 System Integration

The mechanism operates in conjunction with onboard AC generators and electrical protection systems, executing programmed switching of circuits to isolate faulty components. The product is also known under alternative designation PMK-14.
