Vector Technics DC DC Converter Voltrox 12V BEC

The Voltrox 12V BEC by Vector Technics is a high-efficiency, industrial-grade DC-DC buck converter specifically designed for UAVs, robotics, and mission-critical electronics. It is particularly valued for its exceptionally wide input voltage range, allowing it to work with high-voltage battery systems.

Here is the technical breakdown:

Core Electrical Specifications

• Input Voltage Range: 15V to 100V DC (compatible with 6S to 22S+ LiPo setups).

• Output Voltage: Fixed 12V DC.

• Current Output: 2A continuous, with a peak surge capacity of up to 3.4A.

• Efficiency: High conversion efficiency ranging from 86% to 90.61%, which minimizes heat buildup during long flights.

• Voltage Accuracy: 2%, ensuring stable power for sensitive equipment like gimbal motors and FPV gear.

• Ripple & Noise: Low noise profile (80120mVp-p), critical for reducing ce in video and telemetry signals.

Protection & Safety Features

• Over-Temperature Protection: Automatic shutdown if the unit reaches +130C.

• Short-Circuit Protection: Built-in safety that limits current to 110mA in the event of a short.

• Under-Voltage Protection: Triggers at <13.2V to prevent erratic behavior or battery over-discharge.

• Operating Temperature: Rated for extreme environments from -40C to +125C.

Physical Attributes

• Dimensions: Compact footprint at 31 x 20 x 8 mm (some versions listed as 6.75mm height).

• Weight: Ultra-lightweight at approximately 8 1 grams.

• Build Quality: Engineered for high-vibration environments typical of industrial UAV operations.

Primary Use Cases

• UAV Payloads: Powering 12V, and high-power LED navigation lights.

• Flight Avionics: Reliable secondary power for flight controllers or companion computers (like Raspberry Pi or Jetson) when used with a 12V-to-5V step-down.

• Industrial Robotics: Voltage regulation for sensors and communication modules in high-voltage systems.

Note: Because this is a "Buck" (step-down) converter, your input voltage must remain higher than the 12V output. While the spec starts at 15V, it is most commonly used in systems running 22.2V (6S) or higher.
