Protect your power supply from surges caused by sudden braking on a motor controller with this tiny Phidget.

The new generation of motor controllers from Phidgets Inc. are able to rapidly change motor directions, strongly brake the motor, and produce power with regenerative braking. Battery powered systems can easily absorb these surges of power - but most Power Supplies will immediately fail if a power surge is detected on the output.

The SAF2000_0 has three functions:

  • Prevent power on the output from flowing back to the input
  • Clamp the output at 37 Volts during power surges, to protect the motor controllers
  • Conveniently convert a 5.5x2.1mm Power Jack to a terminal block

We strongly recommend using this Phidget according to the table below:
