Our company produces SVC (VAS) type three-phase, three-phase AC voltage stabilizer is a new generation of energy-saving multifunctional voltage stabilizers developed and produced by the market’s voltage stabilized power supply.
It consists of contact autotransformer, servo motor, automatic control circuit (using large-scale linear logic circuit) and other components. When the grid voltage is unstable or the load changes, the automatic control circuit will drive the servo motor according to the ratio of the output voltage, adjust the position of the carbon brushes on the top of the autotransformer, and stabilize the output voltage at the rated value.
VAS Series Voltage regulator is characterized by beautiful appearance, low power consumption and complete protection functions. It can be widely used in industrial production, scientific research, medical and health care and air conditioning, refrigerators and other household appliances, is a performance, the price is more ideal AC voltage regulator.

FAQ
1. What types of voltage stabilizers do you offer?
We offer a full range of automatic voltage stabilizers, including single-phase and three-phase models, suitable for residential, commercial, and industrial applications. Models vary in power capacity and control system.
2. How do I choose the right voltage stabilizer for my application?
Selecting the right stabilizer depends on your input voltage range, load capacity, application type (residential, industrial, etc.), and whether you need single- or three-phase. Our sales engineers can assist you with detailed selection guidance.You can send an email directly to our email address (info@derlicn.com) and get a reply in as little as three hours.
3. Are your voltage stabilizers compliant with international standards?
Yes. All our voltage regulators are manufactured and tested according to IEC standards. CE marking is available on request.
4. What is the input voltage range your voltage stabilizers can handle?
We offer models with wide input ranges, including ±15%, ±20% and customised ranges on request. For areas with extremely unstable power grids, we can also customise ultra-wide rangevoltage regulators for you.
5. What is the MOQ for voltage stabilizers?
Our standard MOQ is 1 unit for trial orders. For OEM/ODM projects or bulk pricing, we typically require a minimum order of 50 units, depending on the model and customization level.
6. Do you provide OEM or ODM service?
Yes, we offer both OEM and ODM services. We can print your logo, customize the housing design, and even our professional engineers can develop new control boards based on your functional requirements.
