1700W Generator Control Unit
The 1700W Generator Control Unit manages the generation and storage of electrical energy to supply the needs of small to medium-sized UAVs.
The GCU is designed to complement the functionality provided by the 900W PDU (Power Distribution Unit). When installed together, these two units form a complete power supply solution including electrical power generation, battery management, power distribution and redundancy for critical sub-systems.
Features
- Main power output provides up to 900W at 57.5V for powering vehicle electronics directly or via PDU.
- Two battery chargers, each capable of providing up to 400W of charging power for rapid in-flight recharging.
- Battery chargers user-configurable for both voltage and current, allowing a wide variety of battery chemistries and sizes to be accommodated. Supported battery types include:
- LiPo: 10-12S
- LiS: 15-20S
- LiFe: 10-14S
- Active rectification of 3-phase inputs achieves highest possible efficiency, minimising self-heating.
- Outputs powered by interleaved, spread-spectrum modulated DC-DC converters for best possible EMI/RFI performance.
- Umbilical input: 35 – 60 VDC.
- RS232 and CAN monitoring interfaces provide extensive reporting of voltages, currents and internal temperature.

User configurable voltage
Customized to your requirements
Standard & single-output version available
Optional starter board
Configurations
All configurations have the same technical features.
The standard GCU has the three separated outputs which are main-output (PDU or direct UAV power source and two separated chargers.
This GCU is designed to be used in hybrid applications and has a single output providing all DC power through a single connector. Applications are hybrid electrical UAVs or in a range extender configuration.
We have a variety of other configurations available, which fit for larger or hybrid UAVs as well. Contact us to discuss your application.
