3A Switch-Mode Ultimate BEC
Why do you need to use UBEC?
The UBEC is a switch-mode DC regulator separated from ESC (ESC---Electronic Speed Controller for brushless motor), 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. If you are using a speed controller with a built-in BEC, it will very likely have only a limited ability to supply power to your receive and servos without overheating. If you have a relatively high-voltage battery pack or have heavy servo loads, you should consult the ESC Specifications to determine what the stated recommendations or limitations are. In general, if you are using a 4S Lithium pack, or more than a 12 cells Nickel based pack, you should consider using the UBEC. In such a case, the built-in BEC of ESC only support 2 servos, so it is not suitable for RC helicopter and big aircraft.

Eliminates the need for a separate battery pack
to power your receiver and servos.

3A 5/6V UBEC HW (MAX 5A)

Item no. EUB3AUBECHW
Features :
1. The UBEC is an advanced switching regulator, provides over-current and over-heat protection function, and the witching frequency is 300KHz. The max efficiency of this chip is 92%
2. The smallest size and the lightest weight.
3. 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.
4. Don't worry about the polarity of battery pack, if the polarity is not correct, the UBEC can't work, but it will not be destroyed. What you need to do is just swap the battery pack polarity.
5. With Shielding Case
