Dualsky VR-3 (UBEC) 3A Switching Mode Voltage Regulator
The VR-3 is a switch-mode DC regulator separated from ESC, it will take high-voltage (5.5V-23V) power from your battery pack and convert it to a consistent safe voltage for your receiver, gyro and servos. The VR-3 allows you to easily choose whether to run your system at 5 or 6 volts. Running at 6 volts gives faster servo speed, and most modern receivers and servos will work fine at this voltage.
- VR-3 is an advanced switching regulator, provides over-current and over-heat protection function, and the switching frequency is 300KHz.The max efficiency of this chip is 92%.
- The smallest size and the lightest weight.
- Compare linear BEC with switch-mode BEC: When using a lithium battery pack more than 3s, a switch-mode BEC has much higher efficiency than linear BEC.
- Reverse polarity protection at input is provided.
