Featuring a digital LED display, intelligent CPU control, and heavy-duty toroidal transformer technology, it continuously stabilizes fluctuating grid voltages (110V/120V/220V/230V) to safeguard sensitive appliances, air conditioners, and office equipment. Capacity Range: 3kVA, 5kVA, 8kVA, 10kVA, 15kVA Mounting Type: Wall-Hanging / Space-Saving Compact Design Voltage Options: Input 120V–260V / 90V–250V AC to Output 220V / 110V ±3% or ±8% Key Features: Digital LED display, silent operation, dual output sockets/terminals, full overload protection Factory Service: Direct Manufacturer Supply | Custom Branding & Outlets | OEM/ODM Global Delivery
In residential apartments, small offices, and retail stores, floor space is premium real estate. Traditional bulky floor-standing voltage regulators often obstruct walkways and create wire clutter.
Our Wall-Mounted Single Phase Automatic Voltage Regulator (AVR) solves this challenge by combining robust voltage stabilization with an ultra-compact wall-hanging form factor. Available in capacities from 3kVA up to 15kVA, it mounts securely onto any vertical wall surface. Powered by advanced microcontroller (MCU) circuitry and a toroidal transformer, it automatically corrects power sags, surges, and brownouts to deliver clean, stabilized AC power to high-draw loads like air conditioners, heat pumps, computers, and medical instruments.
Sleek Wall-Mounted Design: Easy vertical mounting frees up valuable floor space, keeps wires organized, and presents a modern aesthetic.
Intelligent Digital LED Display: Dual real-time LED screens display input voltage, output voltage, load capacity percentage, and protection status at a glance.
Wide Capacity Range (3kVA – 15kVA): Covers light residential needs (3kVA/5kVA for single appliances) up to whole-house or commercial facility protection (10kVA/15kVA).
Toroidal Transformer Efficiency: High-efficiency copper/aluminum toroidal transformer offers quiet operation, low electromagnetic interference, and minimal self-loss.
Comprehensive Safety Safeguards: Built-in protection against over-voltage, under-voltage, short-circuit, thermal overload, and adjustable power-on time delay.

Our 3kVA to 15kVA wall-mounted stabilizers are ideal for space-sensitive installations:
Residential Houses & Apartments: Whole-house protection, split air conditioners, large refrigerators, and washing machines.
Commercial & Retail: POS terminals, security systems, server racks, and office AC units.
Medical Clinics & Labs: Diagnostic devices, dental chairs, and refrigeration units.
Q1: What is the difference between a Servo-type and Relay-type wall-mounted stabilizer?
A: Relay-type wall stabilizers offer faster switching speed, smaller weight, and lower cost with ±8% output precision, making them great for general home appliances. Servo-type wall stabilizers provide higher accuracy (±3%) and stepless voltage regulation, ideal for sensitive electronics.
Q2: How do I choose the right capacity (e.g., 5kVA vs 10kVA) for my customer?
A: A 3kVA to 5kVA unit is usually sufficient for single heavy appliances like a 1.5–2.5 HP air conditioner or refrigerator. A 10kVA to 15kVA unit is recommended for whole-apartment power supply or multiple simultaneous motor loads.
Q3: Does the package include wall-mounting brackets and hardware?
A: Yes! Every wall-mounted AVR comes complete with heavy-duty mounting brackets, expansion bolts, and an installation manual for quick and safe mounting.
