What Is a Step Down Transformer with Voltage Stabilizer?
This device is an all-in-one solution that combines a transformer (for voltage conversion) and a stabilisateur de tension du servo (for voltage regulation). Designed for seamless power adaptation, it converts high input voltage (e.g., 220V–250V) to a safe, usable level (typically 110V), while also correcting for voltage fluctuations, spikeset dips in real time.
Unlike standalone transformers, this integrated system ensures your equipment is not only powered correctly—but also protected.

FAQ
1. Can I use this device with American appliances in Europe or Asia?
Yes. This unit converts 220–250V down to 110V while stabilizing the output, making it perfect for US appliances used abroad.
2. Is this suitable for continuous use?
Absolutely. SUNWAY’s units are designed for long-term, stable operation with built-in temperature and overload protections.
3. What happens if the voltage goes too high or low?
The device will automatically trigger protection mechanisms, such as cut-off or delay restart, to safeguard connected equipment.
