How to Choose the Right Model

► Measure the mains voltage drop after turning on your appliances.
► The no-load voltage is a "phantom voltage" and cannot be used as a reference.
► The lower the input voltage, the smaller the effective power of the stabilizer.
► For inductive loads (air conditioners, water pumps, etc.), calculate the required power at 3x the rated load power.
► For other loads, calculate at 2x the rated load power.
► For specific recommendations, please consult our customer service.

Frequently Asked Questions (FAQ)

What causes voltage fluctuations and why do I need a stabilizer?

Voltage fluctuations occur due to distance from power stations, overloaded transformers, or high power demands in nearby areas. A stabilizer ensures steady output voltage to prevent equipment malfunction and extend appliance lifespan.

How do I size the stabilizer for my appliances?

For resistive appliances, allow double (2x) the rated power. For inductive loads with motors (like pumps, refrigerators, or air conditioners), size the unit at least three times (3x) the rated power due to start-up surges.

What protection mechanisms does the TND series include?

The system features integrated protection circuits that safe-guard against overvoltage and overcurrent situations, disconnecting or regulating output automatically when thresholds are exceeded.

Can this unit operate in extreme weather conditions?

The unit has an ambient operating temperature range of -10°C to +40°C. Ensure installation takes place in a well-ventilated, dry indoor location shielded from high humidity and direct sunlight.

What is the difference between horizontal and vertical models?

Vertical models (available for 5K and 10K capacities) offer a smaller physical footprint to fit compact utility spaces while providing identical performance and electrical specifications as their horizontal counterparts.
