What Is a Volt Stabilizer?
A volt stabilizer—also known as a voltage regulator—is an essential electrical device that maintains a stable voltage output regardless of input voltage fluctuations. It protects sensitive equipment like home appliances, computers, and industrial tools from damage caused by overvoltage or undervoltage conditions. The DVT Series by SUNWAY is designed to deliver consistent, safe voltage with high efficiency and intelligent control.

DVT vs. Similar Technologies
Compared to servo-type stabilizers or tap-changing regulators, the DVT relay-type series offers:
- Faster Switching Time
- Lower Cost
- No Mechanical Wear Components
- Excellent for Residential and Small Business Use
Servo stabilizers may be more precise, but relay stabilizers like the DVT are faster, lighter, and more economical—ideal where ±10% output is sufficient.
Choosing the Right Model
When selecting your volt stabilizer:
- Calculate Total Load: Add up wattage of devices to be protected.
- Account for Surge Power: Especially for equipment like fridges, pumps, or motors.
- Pick a Power Range: Select a stabilizer with 20–30% higher VA rating than your total load.
Quick Guide:
- DVT-500VA / 1000VA: Ideal for routers, TVs, and single appliances.
- DVT-1500VA / 2000VA: Suitable for PCs, washing machines, or small office setups.
- DVT-3000VA / 5000VA: Recommended for air conditioners, home theaters, or multi-device environments.
ЧАСТО ЗАДАВАЕМЫЕ ВОПРОСЫ
Q1: Can I use the DVT Series stabilizer with a generator?
A1: Yes. The DVT stabilizer works with most generators, but ensure your generator’s output voltage is within the supported range (45–260V) and its wattage meets the stabilizer’s input requirements.
Q2: Will the stabilizer protect against power cuts or lightning?
A2: The stabilizer offers protection from voltage spikes and drops but not complete lightning protection. For full surge protection, pair it with a certified surge protector.
Q3: What happens if the input voltage goes below 45V or above 260V?
A3: The stabilizer will shut down or bypass operation to prevent equipment damage. For extreme voltage environments, consider a customized input range.
