SVC Wall-Mounted Automatic Voltage Regulator
Not every installation has room for a floor-standing cabinet. The SVC mounts directly on a wall, keeping single-phase voltage regulation out of the way in spaces where floor space is limited — utility closets, equipment rooms, and light commercial installations. A smart control chip continuously reads input voltage across a 110-260V window (140-260V on the standard-voltage model) and drives a dual-head carbon brush across a dual-wound pure copper coil to hold output at 220V ±3%, correcting within 1 second of a 20V input change. It’s built for a wide range of connected equipment — from air conditioners, computers, and medical devices to CNC machines, industrial automation equipment, and photo-processing labs — anywhere a wall-mounted footprint matters more than raw capacity.





Key Features
Compact enough to mount on a wall, precise enough for equipment that can’t tolerate voltage swings.
Compact Wall-Mounted Design
Mounts directly on a wall, freeing up floor space in utility closets, equipment rooms, and light commercial installations.
Smart Chip-Based Regulation
Continuously reads input voltage across a 110-260V or 140-260V window and intelligently adjusts output to a steady 220V.
Dual-Head Carbon Brush
An enlarged dual-head brush design improves regulation timing and accuracy over a standard single-brush setup.
Full-Power Dual Copper Coil
Dual-wound pure copper coil construction keeps windings tightly spaced for stable, durable long-term operation.
Clear LCD Voltage Readout
High-definition display gives an at-a-glance, precise voltage reading.
Lightning Protection & Multiple Safeguards
Built-in surge protection alongside multiple safety protections for stable output and quiet, efficient heat dissipation.
