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.

Features

  • Prevents 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:

Recommended Use

Power Supplies

This Phidget protects a power supply between 0 and 30V DC. Check the product page or data sheet of the device being powered to determine how much current is needed and what voltage range is permissable. Select the power supply from the list below that matches your region's wall socket type.

Getting Started

Welcome to the SAF2000 user guide! In order to get started, make sure you have the following hardware on hand:

Next, you will need to connect the pieces:

  1. Connect the power supply to the barrel jack on the SAF2000.
  2. Connect wires from the SAF2000's ground and power terminals to the device's ground and power terminals. Ensure that you use wire of appropriate gauge for the amount of current in your system.
  3. Follow the instructions on the User Guide for the powered device you're using.


Technical Details

The SAF2000 protects both your power supply and your device from voltage spikes caused by reverse EMF generated by braking and reversing DC motors. In the event of such a surge, it prevents current from flowing back into the power supply and clamps the powered device's supply voltage to a maximum of 37V, dissipating the excess power until the surge has passed.

This device uses a diode to prevent current flowing back into the power supply, so expect a slight drop in the voltage seen by the powered device when in normal operation.
