Veronte R12S DC-DC converter

Veronte R12S is a redundant DC-DC converter for PMU modules and avionics power distribution, made by Embention as part of its Veronte avionics ecosystem. It is a miniaturized step-down converter with a switch-selectable output, designed to supply critical onboard electronics in professional unmanned aircraft and other autonomous vehicles from a higher-voltage battery or bus.

The function of the unit is to regulate a variable input into a stable rail for flight computers, sensors, radios and payload electronics. Because it is a buck-only converter, the input must always sit above the selected output voltage; it cannot raise voltage. Each unit is therefore chosen according to the main bus of the vehicle and the rail required by the load.

The figures that matter in integration are these. The input range is 5.5 V to 36 V, which covers batteries from a single high-voltage cell to roughly 8S lithium packs without an intermediate stage. The output is selected with a switch among 3.3, 5, 6, 7.4, 9 and 12 V. Exactly one output switch must be on: with none or more than one on, the output voltage is undefined, so the setting is a verification item in the installation checklist. Output current is 5 A both continuous and peak, and the operating temperature range is -40 to 85 degrees C. Mass is 19 g.

Redundancy is the reason for the product. More than one R12S can be connected in parallel when all units are set to the same output voltage, so the load is fed through several converters and a failure of one does not remove the rail. An optional pad lets a flight controller switch the output on or off through a GPIO line, which supports power sequencing and remote reset of a subsystem.

Mechanical installation uses two M3 screws, and the pinout is Vin, GND and Vout, with all ground holes and pads common. In saline environments such as coastal and oceanic use, the maker requires stainless steel screws. Typical applications are redundant power architectures in UAS, eVTOL prototypes and autonomous vehicles that carry Veronte autopilots or third-party avionics.
