9V 4.5A Regulator UBEC


The 9V 4.5A Voltage Regulator – more power for your robot without overloading

  • Looking for a way to get more power from your servo?
  • Want to run your robot’s drive system off 11.1V or more, but the servo can’t go that high?
  • This 9V 4.5A Voltage Regulator will supply 9V from any battery up to 23V.
  • 4.5A is enough to power even our strong metal gear servos (four of them, in fact)!

The 9V 4.5A Voltage Regulator

Parameter: Value:
Input: 6-23V (does not change voltages below 9V)
Output: 9V, up to 4.5A
Dimensions: 41 x 22 x 14mm (1.61 x 0.87 x 0.55in)
Servo wire length: 13cm (5.1in)
Weight: 12.5grams (0.44oz)

Includes ferrite bead for smooth output voltage. (Less than 50mV peak to peak voltage @ 2A)

To hook up in your robot:

  1. Run the regulator’s IN+/- wires to your battery (through your power switch).
  2. Pull the servo’s center wire (positive, red) from the connector then plug the connector (orange and brown) into your receiver.
  3. Connect the servo’s center wire (positive, red) to the regulator’s OUT+ (red) wire.
  4. Connect the regulator’s ground wire (black) to one of the receiver’s ground terminals.
  5. Your receiver will still need a 5V supply. This is normally provided by the drive motor controllers (like tinyESCs).
  6. Connecting multiple things to a single source is made easier with mini terminal blocks.

Now your drive motors get full battery voltage (up to 23V), the receiver has its required 5V, and your servo is running at its optimal 9V!
