Three-phase inverter voltage stabilizer Volter Prostor-33 (33.0 kW) is a innovative inverter device Prostor-33, developed for reliable safety of home and professional electrical equipment from any emergency situations 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 houses, apartments, and offices where stable and safe operation is critical of demanding equipment.
The operation of this unit is based on advanced double conversion inverter technology. The device in real time 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regulation principle, the voltage is corrected absolutely smoothly, without any fluctuations or delays typical of outdated relay or step-type devices.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 device holds output voltage within strict limits of 217.8 V to 222.2 V, providing ideal conditions even for high-precision medical or laboratory equipment.
- Operating conditions: adaptation to standard temperatures ensures stable operation of the device in residential, office, and any heated rooms.
- Alternative grid operation: the unit is fully compatible for operation with hybrid solar power stations (handles reverse current) and autonomous fuel generators.
- Resource and durability: due to the use of electronic semiconductor switches, the device runs quietly and does not create acoustic discomfort.
- Unlimited support: official warranty conditions from the manufacturer confirm impeccable assembly quality and durability of all components.
Safety and Protective Functions
- Emergency overload shutdown: protective power cut-off upon long-term exceedance of the allowable load power.
- Temperature control: constant overheat protection of power switches and autotransformer with automatic fan launch.
- Emergency short circuit trip: ultra-fast output de-energization to a short circuit in the connected load to prevent damage to power modules.
- Impulse spike protection: effective absorption of high-voltage noise in the mains grid caused by external factors.
Installation and Connection Recommendations
- Wall-mounted installation: the stabilizer body is securely fixed on a vertical surface using included mounting elements.
- Clearance for ventilation: leave free space around ventilation openings (at least 10–15 cm) for unobstructed forced cooling.
- Power cables connection: connection to power supply lines is carried out via terminal strip. The copper feeder cable cross-section must correspond to maximum device current.
- Environmental conditions: 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 power parameters of the model are suitable for protection of all appliances in a large cottage, office, or commercial site.
- Boilers and pumps: creates a perfect sinusoidal signal, which is necessary for gas and solid-fuel boiler automation.
- Local networks: prevents data loss and malfunctions of computer systems, servers, and network switches.
- Diagnostic devices: provides the necessary voltage quality for dental units and precise diagnostic tools.
