GreenStar AVI actively protects solid state electronic devices from damaging transient voltage events. The AVI will interrupt AC supply voltage if an electrical transient sags below 85V or swells above 300V. Rated for >300,000 transient interruptions, the AVI will protect and extend the life of your electronic devices. Originally designed for outdoor LED luminaires, which typically exhibit transient damage by blinking, the AVI will work well on any device that uses electronic control.
