Three-phase inverter voltage stabilizer Volter Prostor-27 (27.0 kW) is a high-tech inverter device Prostor-27, developed for reliable safety of sensitive electronic electrical equipment from critical surges in the grid. It works as an effective shield against dangerous impulse surges, long voltage sags, line interference, and current frequency fluctuations. Thanks to high power capacity, this stabilizer is an excellent solution for facilities with a corresponding number of loads where stable and safe operation is critical of sensitive appliances.
The operation of this model is based on advanced double conversion inverter technology. The device in real time 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stepless regulation principle, the voltage is corrected most gently, without the slightest jumps or delays typical of outdated relay or step-type devices.

Key Benefits of the Model
- Ultra-high accuracy (±0.50%): the device preserves output voltage within strict limits of nominal values, providing ideal conditions even for sensitive medical or laboratory equipment.
- Climatic design: adaptation to standard temperatures guarantees reliability of the device in standard operating conditions.
- Compatibility with solar and generators: the unit is fully compatible for operation with solar station inverters (handles reverse current) and generator sets.
- Silent operation: due to the use of electronic semiconductor switches, the device runs almost silently 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 automatic fan launch.
- 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 vertically on the wall using included mounting elements.
- Air circulation assurance: leave free space around ventilation openings (from 10 cm) for unobstructed forced cooling.
- Terminal grid connection: connection to power supply lines is carried out via terminal block. The copper feeder cable cross-section must correspond to maximum device current.
- 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 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 gas and solid-fuel boiler automation.
- Server systems: protects network equipment computer systems, servers, and network switches.
- Specialized equipment: maintains stable power for dental units and precise diagnostic tools.
