Primary Power Distribution Control Systems
RSL has extensive experience in the design and development of complex Primary Power Distribution Control Systems intended ,among other uses, for MALE UAV's
The specifications of the system differs according to the specific platform it is designed for.
the following is representative characteristics of one of our current in-service systems:
Input power includes:
- One or two generators of 28 Vdc,
- External Power including Power Quality Monitoring
- High capacity backup batteries
- High current battery for Start operation
Microprocessor control and management of electrical energy:
- Engine Start sequence control
- Voltage monitoring for Contactor and power fuses
- Current monitoring for main power busses
- Contactors and Relays control by local microprocessor
- Communication channels to platform's on-board computer for command, control, monitoring and BIT
Mechanical:considerations:
- Integrated designs for significant weight and volume savings
- Aluminum Busbars for weight reduction
- Housing made of sheet metal for weight reduction
Safety:
- “Design-to-safety” electronics and Contactors activation
- Fully reprogrammable control logic
- BITE features such as Fully Automatic Power On Built-in-Test (PBIT) and Continuous Built-in-Test (CBIT)
- Over-current, short circuit, reverse current protection
- Under- and over-voltage protection by Microprocessor control
- Mil-Std-704 over voltage protection
Various communication buses (RS422/485, Ethernet buses, etc.) for communication with platform's on-board computer, and other aircraft equipment, as well as for Ground Support Equipment
Distributed or integrated architecture to optimize electrical power system performance, installation, heat dissipation, safety and reliability
