Three-phase inverter voltage stabilizer Volter EtalonS-27 (27.0 kW) is a modern inverter device EtalonS-27, developed for effective protection of home and professional electrical equipment from critical surges in the grid. It reliably protects against dangerous impulse surges, mains voltage drops, line interference, and sine wave distortions. Thanks to high 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 device is based on advanced double conversion inverter technology. The device constantly converts incoming AC power into DC and then creates 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the stepless regulation principle, the voltage is corrected most gently, without any fluctuations or delays typical of outdated relay or step-type devices.

Key Benefits of the Model
- Stable output parameters (±1%): the stabilizer holds output voltage within strict limits of nominal values, providing ideal conditions even for high-precision medical or laboratory equipment.
- Operating temperature range: operating temperature range (from +5°C to +40°C) ensures stable operation of the device in standard operating conditions.
- Synchronization with autonomous power: the unit is adapted for operation with hybrid solar power stations (handles reverse current) and generator sets.
- Quiet execution: due to the absence of moving mechanical parts, the device runs quietly and eliminates sparking and wear.
- Quality guarantee: unprecedented warranty conditions from the manufacturer confirm impeccable assembly quality and durability of all components.
Safety and Protective Functions
- Critical current overload protection: automatic de-energizing of the device upon long-term exceedance of the allowable load power.
- Multi-level thermal protection: constant temperature monitoring of power switches and autotransformer with activation of forced cooling ventilation.
- Short circuit protection: instant reaction to a short circuit in the connected load to prevent damage to power modules.
- Impulse and lightning surge filtration: effective smoothing of high-voltage spikes in the mains grid caused by external factors.
Installation and Connection Recommendations
- Wall vertical mounting: the stabilizer body is securely fixed on a vertical surface using mounting plate or anchors.
- Air circulation assurance: leave free space around ventilation openings (at least 10–15 cm) for effective heat dissipation.
- Terminal grid connection: connection to power supply lines is carried out via terminal strip. The copper feeder cable cross-section must correspond to nominal load.
- External exposure protection: the device has IP20 standard 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 stabilizer nominal power are designed for protection of all appliances in a large cottage, office, or commercial site.
- Heating and water systems: provides a pure sine wave, which is necessary for circulation pumps and sensitive control boards.
- Server systems: protects network equipment computer systems, servers, and network switches.
- Specialized equipment: maintains stable power for dental units and precise diagnostic tools.
