VISIONAIRtronics is a leading developer of high-reliability power management systems and propulsion solutions for tactical UAVs (unmanned aerial vehicles) and other uncrewed vehicles.
Our rugged and reliable products are designed with maximum safety and efficiency in mind, ensuring success for military, government aerospace operations in challenging and dynamic environments.

Our field-proven products have been selected by leading defense primes and unmanned systems manufacturers for incorporation into UAVs, UGVs and space craft.
900W Power Distribution Unit
Redundant power distribution for small and medium-sized UAVs
The 900W Power Distribution Unit takes in unregulated battery voltage from 24 to 60 VDC and delivers regulated outputs for distribution to subsystems within small to medium-sized UAVs. Three main independent and user-configurable power outputs are provided for avionics, servos and payloads. The avionics and servo supplies are fully duplicated for redundancy to ensure maximum safety and reliability for critical drone operations.
1800W Dual Power Distribution Unit
Redundant power distribution for medium to large-sized UAVs
The 1800W Power Distribution Unit takes in unregulated battery voltage from 24 to 60 VDC and delivers regulated outputs for distribution to subsystems within medium to large-sized UAVs. Six independent and user-configurable power outputs are provided for 2x avionics, 2x servos and 2x payloads, with avionics and servo supplies fully duplicated for redundancy and maximum reliability. Two low-power redundant 5V outputs are also provided to power external sensors.
The system can be monitored via RS232 serial or CAN and provides comprehensive voltage, current, power data and health information. It is available in a rugged IP66-rated enclosure.
1700W Generator Control Unit
Power management system for small and medium-sized drones
The 1700W Generator Control Unit (GCU) provides and manages electrical generation and storage for small to medium-sized UAVs. It provides a main power output of up to 900W at 57.5V, and includes two user-configurable battery chargers that each deliver up to 400W for rapid in-flight recharging.
The GCU can be combined with our 900W Power Distribution Unit or our 1800W dual-PDU to provide a complete drone power supply solution, including electrical power generation, battery management, power distribution and redundancy for critical sub-systems.
The system can be monitored via RS232 serial or CAN, and provides comprehensive voltage, current and internal temperature data. It is available in either a regular slimline or rugged IP67-rated enclosure.
Our new modular variant is capable of a variety of output configurations, such as single, dual or triple output, for the many differences in UAV platforms electrics needs.
15S Battery Monitor & Balancer
Enhanced battery life and reliability for tactical UASThe 15S Battery Monitor & Battery Balancer transforms ordinary drone batteries into smart self-balancing power sources. Supporting 9 to 15S batteries with LiPo, LiS or LiFe chemistries, the compact precision instrument allows multi-cell batteries to operate more efficiently and reliably, and last for longer without replacement.
The unit sends comprehensive data, including internal state, voltages, currents and temperatures, to the UAV’s CAN bus, and two front-panel LEDs provide “go/no go” indication of battery balance and charge.
UAV Small Engine Starter
Starter for UAV internal combustion enginesThe UAV Engine Starter provides rapid and reliable starting of internal combustion engines without requiring the use of decompression valves. Compatible with drone engines up to 200 cc in size, it delivers maximum torque from standstill, and allows remote engine starting and in-flight restarting.
