Power Distribution Solutions
Reliable power distribution for UAVs of various sizes
Our Power Distribution Solutions accept unregulated battery voltages ranging from 24 to 60 VDC and provide regulated outputs for subsystems in small to medium UAVs. We offer two models, delivering either 900 or 1800W of total output power.
900W Onboard Power Distribution Unit
1800W Onboard Dual-Power Distribution Unit
The 900W PDU features four independent power supply outputs, with three (including a low-power 5V output) ensuring full redundancy for enhanced safety and reliability during critical drone operations. The 1800W model provides eight outputs—two each for avionics, servos, payloads, and low-power—with redundancy on avionics, servo, and low-power supplies.
All units can be monitored through RS232 serial or CAN, offering detailed voltage, current, power data, and health metrics, all housed in a robust IP67-rated enclosure for reliable performance in harsh environments.
