Watch | Controlling High Voltage/High Current Loads Using Low Voltage Control Signals

In this video, Jon Gabay demonstrates a technique for controlling high voltage and high current loads with low voltage control signals.

Instead of using traditional electromechanical relays, which can wear out over time, he’ll use an opto isolator for improved durability and faster switching. You’ll learn how to safely bias an LED to activate a transistor, enabling current to flow to your high-voltage loads.

We’ll also explore how this method saves costs by allowing the use of thinner wires for high-voltage applications. Perfect for anyone working with high-current systems and looking to optimize their circuit design!
