Functions

Automatic voltage stabilization – maintains a more stable output voltage even during large power grid fluctuations
Overvoltage protection – protects connected equipment from dangerous power surges
Undervoltage protection – prevents equipment from operating under unstable or excessively low voltage conditions
Overload protection – automatically protects the system from excessive load
Short circuit protection – helps prevent equipment damage in case of an авария
LED voltage display – displays input and output voltage parameters in real time
Relay control – quickly reacts to network changes and stabilizes voltage
Start delay – protects compressor equipment and sensitive electronics after a power outage
Universal application – suitable for both household and professional equipment

Usage

At home and in country houses: An excellent solution in areas where lights flicker, voltage drops occur, power outages are frequent, or old electrical networks are used. The stabilizer protects televisions, refrigerators, computers, WiFi routers, gas boilers, heat pumps, and security systems.
For electricians: Used when designing backup power systems, server rooms, automation cabinets, security systems, video surveillance systems, and UPS circuits.
For engineers and technical personnel: Helps stabilize production equipment, laboratory instruments, sensitive electronics, CNC machines, and measurement systems.
For offices and commercial premises: Suitable for cash registers, servers, network equipment, computers, and security systems.
