We design and fabricate voltage regulators and power distribution systems for our alternators and for other power systems.
In many cases, the voltage regulation and power distribution system must be customized for the application. Depending on the equipment being powered, the system may need to supply multiple voltages.
Some systems have one or more backup batteries. Usually, the power distribution structure needs to integrate the backup batteries. This can be done with a simple ORing diode, or with a switching circuit. The switching circuit allows you to charge the backup battery if needed.
Airframe PMUs are designed to provide power over a wide RPM range, to reduce the amount of time using the backup batteries. Units are lightweight, have forced air cooling, and are highly efficient for minimum fuel consumption.
PMUs are manufactured for harsh environments including high altitude, extreme temperatures, and high vibration. Environments typically seen in commercial and military aircraft operation.
