60W
Redundant
Power Supply
The Redundant DC Power Supply consists of two identical DC-DC switching converters and a low-loss (ideal diode) power combining stage. It is intended as a high-reliability source of power for mission critical UAV sub-systems.
The output voltage may be set to 5, 12 or 16V using the on-board switch and a screwdriver. Inputs are reverse polarity protected, and the input voltage range extends to +50VDC, al-lowing direct connection of LiPos up to 12S.
Each DC-DC converter is capable of delivering up to 3 Amps continuously with up to 96% efficiency. The output tolerates a short-circuit to ground indefinitely.
Features
- low weight
