How It Works
Startup:
When powered on, the stabilizer enters a delay phase. Once the delay timer ends, the output voltage becomes active and stable.
Protection Activation:
If the input voltage exceeds safe limits, the stabilizer automatically cuts off the output. The LED panel will display “H” (overvoltage) or “L” (undervoltage). It automatically resumes once voltage returns to normal.
Overload Handling:
Models ≤1.5KVA use built-in overload protection.
Models ≥2KVA use a circuit breaker for short-circuit and overload safety.
Display Functions:
The digital LED screen displays output voltage by default. Press the voltage button to view input voltage.
Applications
Perfect for residential and small commercial power protection, including:
Home appliances (TVs, refrigerators, washing machines, air conditioners)
Computers and office equipment
Audio systems and lighting
Laboratory and test equipment
Safety & Installation Notes
Always connect the ground terminal securely before operation.
Install in a dry, well-ventilated area free from dust or corrosive gases.
Do not cover the stabilizer to allow proper heat dissipation.
Avoid connecting AC contactors or relays to the input side.
Clean dust regularly after one year of use for optimal performance.
