FAQ
Q1: How do I choose the right stabilizer capacity for my home appliances?
A1: Add up the wattage of all appliances you want to connect, then multiply by 2–3 to allow headroom for startup surges (especially for refrigerators or ACs). For example, a 1500W load should use at least a 3kVA+ stabilizer.
Q2: What’s the difference between relay type and servo type stabilizers?
A2: Relay type stabilizers use electromagnetic switches to regulate voltage and are faster and more affordable—ideal for home use. Servo types are motor-driven, more precise, and suited for sensitive industrial or medical equipment.
Q3: Is the DNB stabilizer safe for air conditioners and refrigerators?
A3: Yes! The DNB series features a built-in time delay function and compressor-friendly protection, making it ideal for AC units and cooling appliances.
