What Is a Digital Power Supply?

A digital power supply uses digital signal processors or microcontrollers to control output through software algorithms instead of analog circuits. It supports communication protocols like CAN or PMBus, enables remote monitoring, and provides precise, efficient, and programmable power control. Compared to analog supplies, it delivers higher accuracy, better efficiency, and advanced monitoring—making it ideal for data centers, EV chargers, and industrial applications.
