3A 5V switching voltage regulator

All model airplane/heli needs reliable power to receiver

Bee's BEC 3A-5V (switching voltage regulator) is a light weight, high efficiency and very reliable Voltage regulator . With this product, you can use your lipo battery as power supply for your receiver and servos safely. Even sometimes your servo load changes rapidly in short time, SVR3-5V can feed steady and constant 3A 5V to the receivers to keep it works well.

Unlike other switching regulator, Bee's BEC3A 5V  is working at higher frequency.  It is more efficient and less radio noise, very reliable.



Weight: 5.4g

Dimension: 42x13.5x.5mm

Input voltage: 6-17V

Output voltage: 5.0V

Output current: continuous 3A, 4.0A for 20 seconds, 5.0A for 15 seconds with good airflow.

Conversion efficiency: 90-93%


Liner type voltage regulator only shows theoretical performance.

If one voltage regulator is using 5A5W chip, it says 5A. However, this chip has only 5W power. In this case to drop from 12V(Lipo3cell) to 5V is 7V, and 5W on 7V is 0.714A. This chip can only provide 0.714A only.

Other switching regulator use 200kHz. Bee's BEC3 use 330kHz.


Above connectors are available for 2-4 cells lipo pack.
