Three-phase inverter voltage stabilizer Volter Smart-81 (81.0 kW, frost-resistant) is a innovative inverter device Smart-81, developed for effective protection of sensitive electronic electrical equipment from unpredictable voltage fluctuations in the grid. It reliably protects against dangerous impulse surges, long voltage sags, line interference, and sine wave distortions. Thanks to appropriate power capacity, this stabilizer is the perfect option for facilities with a corresponding number of loads where it is necessary to ensure stable operation of demanding equipment.
The operation of this unit is based on advanced double conversion inverter technology. The device constantly converts incoming AC power into DC and then shapes output AC power with a pure sine wave and a fixed value of 220 V. Thanks to the stepless regulation principle, the voltage is corrected absolutely smoothly, without any fluctuations or delays typical of outdated relay or step-type devices.

Key Benefits of the Model
- Exceptional output stability (±0.50%): the stabilizer preserves output voltage within strict limits of 217.8 V to 222.2 V, providing ideal conditions even for high-precision medical or laboratory equipment.
- Temperature resistance: wide operating temperature range (from -25°C to +40°C) allows mounting the device in cold garages, vestibules, basements without risk of emergency modes.
- Alternative grid operation: the unit is adapted for operation with solar station inverters (handles reverse current) and autonomous fuel generators.
- Resource and durability: due to the absence of moving mechanical parts, the device runs almost silently and does not create acoustic discomfort.
- Unlimited support: unprecedented warranty conditions from the manufacturer confirm exceptional reliability of the device and durability of all components.
Safety and Protective Functions
- Emergency overload shutdown: automatic de-energizing of the device upon dangerous exceedance of the allowable load power.
- Temperature control: constant temperature monitoring of power switches and transformer with automatic fan launch.
- Emergency short circuit trip: instant reaction upon short circuit occurrence to prevent damage to power modules.
- Impulse spike protection: effective smoothing of high-voltage spikes in the mains grid caused by lightning or switching processes.
Installation and Connection Recommendations
- Wall vertical mounting: the stabilizer body is securely fixed vertically on the wall using mounting plate or anchors.
- Air circulation assurance: leave free space around ventilation openings (from 10 cm) for effective heat dissipation.
- Terminal grid connection: connection to power supply lines is carried out via terminal block. The copper feeder cable cross-section must correspond to nominal load.
- External exposure protection: the device has IP20 protection class, which implies installation in rooms with moderate humidity and dust levels.
Application Area: Where the Device is Used
- Cottages and private houses: the power parameters of the model are designed for safe operation of all appliances in a large cottage, office, or commercial site.
- Boilers and pumps: provides a pure sine wave, which is critically important for gas and solid-fuel boiler automation.
- Local networks: protects network equipment office appliances from sudden impulse noise.
- Diagnostic devices: maintains stable power for sensitive electronic equipment in clinics.
