Q1: What's the difference between the 95-125V and 190-250V input ranges? How does the stabilizer handle them?
The stabilizer is designed for dual voltage regions. The 95-125V range is typically for 110V-120V regions (like North America, Japan), while the 190-250V range is for 220V-240V regions (like Europe, Asia, Africa). The unit automatically detects which input range is active and stabilizes it to the corresponding 110V or 220V output. You must ensure your appliance's voltage rating matches the selected output.
Q2: How do the automatic restart and time-delay functions work together?
These are sequential protective features. When power returns after a cut-off (due to high/low voltage or a blackout), the time-delay system (typically 3-8 minutes) activates first. This critical pause allows the mains voltage to stabilize completely. Only after this delay period ends does the automatic restart function engage, safely reconnecting power to your appliances. This prevents damage from rapid on-off cycling or unstable initial power.
Q3: Can this 5kVA stabilizer protect my entire house?
A 5kVA (5000VA or approximately 4000-4500W) stabilizer can protect a significant portion of the essential circuits of a small to medium apartment or home. It is suitable for powering and protecting multiple appliances simultaneously, such as an air conditioner, refrigerator, TV, and lights. For whole-house protection in larger homes with many high-power appliances running concurrently, a professional load assessment is recommended to determine if a higher capacity unit is needed.
