- Relay: It corrects voltage very quickly by switching "steps" with electronic switches (relays). It is economical and lightweight, but the adjustment is done in steps (makes a "click"); ideal for simple household appliances (refrigerators, televisions).
- Servo: It corrects voltage with absolute precision and smoothness using a small electric motor. It is more expensive and heavier, but ideal for sensitive electronics, audio, and medical equipment that require stability.
