3119-2829-0106, 6A BEC / Voltage Regulator (6-24V Input, 5V, 6V, 8.4V, 12V Output, XT30 Connectors)
This 6A BEC / Voltage Regulator reduces input voltage down to one of four selectable output voltages.
The BEC is highly mountable within the goBILDA® ecosystem thanks to the four hex-counterbored thru-holes on the 32mm square pattern that provide for easy one-tool installation.
Tech Terms
In the world of R/C hobbyists, this component is known as a Battery Eliminator Circuit (BEC) because it eliminates the need for additional batteries when a project’s components require different voltages.
To the electrical engineering crowd, this type of BEC is known as a “switching regulator.” A switching regulator is more efficient than other regulators, including linear ones. Within the world of switching regulators, it’s specifically named a “buck converter” because it reduces (“bucks off”) voltage from its input. Buck converters are also called “step-down converters” or “step-down voltage regulators.”
Tech Tip
Incoming voltage (via the BEC’s XT30 input) must be at least 1V above the selected output voltage, set at 5V by default. You can change the output to 6V, 8.4V, or 12V by moving a jumper on the BEC's side.
⚠️WARNING: To prevent damage to the BEC, ensure that the devices you power with it draw a combined current of less than 6A. When powering motors, check their stall current. For example, Yellow Jacket Planetary Gear Motors have a stall current of 9.2A, making them incompatible with this BEC.
