Voltage regulator ZTW 2-6S UBEC 3A 5 / 6V
Designed for 2s-6s input (6-25V DC) and supports continuous output up to 3 amps or short bursts of 5 amps. The output voltage can be set to 5V or 6V depending on your requirements. This is achieved quite easily with the help of a jumper on the output side.
This UBEC uses a switching regulator to reduce the input voltage to something that can be used for the servo in your aircraft. These are useful devices where the number of servomotors installed is probably more than the BEC handle built into your speed controllers, or you use an Opto-free ESC type Opto that provides power to your receiver and servo.
The relatively small size makes this a pretty great universal BEC in small models.
The power cord is 22 AWG (120 mm red and 120 mm black cable)
The signal wire has a universal JR connector at the end of the 280 mm cable (brown, red, orange)
