What Is “Delay Time” and Why Does It Matter?

Jun 19, 2025
When using a voltage stabilizer, you might notice a short pause before it begins supplying power after being turned on or when the power comes back — this is called the delay time.
In our stabilizers, we offer two delay modes:
  • Short delay: 5 seconds
  • Long delay: 200 seconds
  • You can freely switch between them according to your needs.
But what’s the purpose of this delay?
The delay function is essential for protecting equipment with compressors, such as refrigerators, air conditioners, and freezers. These appliances are highly sensitive to sudden voltage returns or frequent power interruptions. Restarting too quickly can severely damage the compressor and shorten its lifespan.
By adding a delay, the stabilizer gives the electrical system enough time to stabilize before allowing power to reach your appliances — a simple but highly effective protection mechanism.
That’s why the delay function is a standard feature in all our voltage stabilizers — small detail, big protection.
