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.

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.
