Brief description
Single-phase voltage regulator 3000w This is a 3000W single-phase voltage stabilizer suitable for home and small shops. It can automatically adjust the 220V voltage to protect TVs, computers, refrigerators and other appliances from damage caused by unstable voltage. It is lightweight and easy to install, especially suitable for areas with large voltage fluctuations, ensuring the safe and stable operation of your appliances. With low power consumption and fast response, it is an ideal protection device for home electricity.
Features
1. Dialect voice control system supports 6 dialect voice commands including Mandarin and Cantonese. Just say “increase voltage” to automatically adjust, solving the complex operation problems of traditional equipment. It can be easily used by both the elderly and children.
2. AR real-life manual scan the QR code on the body with your mobile phone to watch the 3D installation tutorial, guiding users to complete the entire process of wiring and debugging, lowering the threshold for use.
3. Triple lightning protection design built-in gas discharge tube + varistor + TVS diode combination protection, lightning strike survival rate increased to 99.8%.

Applications
1. Power transformation of old residential areas Single phase voltage regulator 3000w solve the problem of unstable voltage in old houses in the 1990s, protect large appliances such as refrigerators and air conditioners, avoid frequent failures caused by voltage fluctuations, and extend the life of appliances by 3-5 years.
2. Exclusive power supply for home audio-visual room – provide pure power for projectors and audio systems, eliminate screen flickering and audio noise, create a professional home theater experience, and improve the picture quality by 40% compared with ordinary electricity.
3. Constant voltage power supply for baby rooms – ensure stable operation of equipment such as milk warmers and humidifiers, automatically adjust when the voltage fluctuates at night, prevent abnormal start and stop of equipment from waking up the baby, and parents can sleep peacefully.
4. In some remote areas or small – scale communication base stations, a single – phase voltage stabilizer can be used to ensure the stable operation of communication equipment such as routers, modems, and wireless access points, helping to maintain a reliable communication network.
Product details

Single phase voltage regulator 3000w The upper part of the body is made of thermosensitive color-changing material, blue below 35℃, orange at 50℃, and red at 70℃, so you can know the status of the device without touching it.

Fitness power generation interface Connect to a spinning bike or elliptical machine, the electricity generated during exercise can assist the voltage stabilizer, which is both environmentally friendly and can save 15% of electricity.

Rat repellent ultrasonic emission When working, it emits 22kHz sound waves that are inaudible to the human ear, effectively repelling rats and cockroaches, and protecting the line from being bitten.
FAQ
Q: Can it be used in rural areas with unstable voltage? ‌
A: Single phase voltage regulator 3000w A wide voltage regulator (140V-280V) designed specifically for rural areas, with built-in lightning protection module and moisture-proof coating, can work even in heavy rain. A village in Hebei has been tested for three consecutive years with zero failures
Q: Does it require professional installation?
A: Equipped with a color wiring diagram and AR teaching APP, just plug in the live wire, neutral wire, and ground wire according to the diagram. The original anti-fool socket design cannot be plugged in reverse, and even primary school students can operate it safely
Q: Is there any noise when the voltage stabilizer works at night?
A: It adopts a graphene heat sink + fanless design, and the night operation noise is <28 decibels (equivalent to the sound of turning pages). It will not affect sleep when used in the bedroom, and it is 60% quieter than traditional voltage stabilizers‌
