Programmable Power Guard Phidget

When high-power motor stalls or stops suddenly, it can generate a high-voltage surge that can damage the circuitry of the motor controller and burn out the power supply. This Power Guard Phidget is designed to protect your hardware from such an event by preventing current from flowing back into the power supply, and by providing a heatsink and fan for the excess power to dissipate. This board is designed for high current systems and is capable of protecting your equipment from even the largest of power spikes. Simply connect your power supply's positive wire to the 8-30V input lug, connect your device's positive wire to the output lug, and wire both grounds to the ground lug.

Power Control and Safety Features

Since this is an intelligent VINT device, the over voltage trigger can be modified in software to accomodate for different power supplies. Similarly, the fan can be switched on or off, or it can be set to turn on when a certain temperature threshold is passed. You can also choose to switch the power off through software, like a relay. Even if communication between this board and the computer is interrupted, it will continue to power the device and protect against the last chosen overvoltage trigger.

Isolated for Stability

The VINT port on this board is electrically isolated from the rest of the board in order to improve stability by eliminating ground loops.
