Single-phase inverter voltage stabilizer Volter EtalonS-4 (3.5 kW) is a high-tech inverter device EtalonS-4, developed for effective protection of sensitive electronic electrical equipment from any emergency situations in the grid. It acts as a reliable barrier against sudden impulse discharges, long voltage sags, high-frequency noise, and current frequency fluctuations. Thanks to appropriate power capacity, this stabilizer is the perfect option for facilities with a corresponding number of loads where stable and safe operation is critical of demanding equipment.
The operation of this model 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regulation principle, the voltage is corrected absolutely smoothly, without the slightest jumps or delays inherent in outdated relay or step-type devices.

Key Benefits of the Model
- Ultra-high accuracy (±1%): the stabilizer preserves output voltage within strict limits of 217.8 V to 222.2 V, providing ideal conditions even for demanding medical or laboratory equipment.
- Climatic design: operating temperature range (from +5°C to +40°C) guarantees reliability of the device in residential, office, and any heated rooms.
- Compatibility with solar and generators: the unit is adapted for operation with solar station inverters (handles reverse current) and autonomous fuel generators.
- Silent operation: due to the absence of moving mechanical parts, the device runs almost silently and does not create acoustic discomfort.
- Lifetime warranty: unprecedented warranty conditions from the manufacturer confirm exceptional reliability of the device and durability of all components.
Safety and Protective Functions
- Critical current overload protection: automatic de-energizing of the device upon dangerous exceedance of the allowable load power.
- Multi-level thermal protection: constant temperature monitoring of power switches and transformer with automatic fan launch.
- Short circuit protection: instant reaction upon short circuit occurrence to prevent damage to power modules.
- Impulse and lightning surge filtration: 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
- Local appliance protection: the stabilizer nominal power are designed for safe operation of individual appliances: refrigerators, TVs, lighting systems, or PCs.
- Heating equipment: provides a pure sine wave, which is critically important for gas and solid-fuel boiler automation.
- Computers and office equipment: protects network equipment office appliances from sudden impulse noise.
- Medical offices: maintains stable power for sensitive electronic equipment in clinics.
