Delay light in automatic voltage stabilizer come on?

In an automatic voltage stabilizer (AVS), the delay light typically indicates a temporary interruption in the output voltage stabilization process. This delay allows the system to assess the incoming voltage and make necessary adjustments without immediately relaying fluctuations to connected devices. The light may remain on for a preset duration to ensure stability before the AVS resumes normal operation, protecting equipment from potential damage due to rapid voltage changes. If the delay light stays on for an extended period, it may signal a malfunction or a fault in the system.
