Digital | Automatic Voltage Stabilizer for Electrical Network | 1P | 3kVA | 160-260VAC | 230V

Wall-Mounted Automatic Voltage Stabilizer – 3 kVA, 230 V, Servo Drive, Copper Winding, LCD

Single-phase wall-mounted automatic voltage stabilizer is designed to supply electrical equipment with stabilized 230 V AC voltage when the mains voltage is too low, too high, or fluctuating.

The device uses a servo motor-controlled voltage regulation system, copper transformer winding, digital LCD display, and integrated protection against overvoltage, undervoltage, overload, overheating, and short circuit.

• Automatic voltage stabilization – corrects fluctuating mains voltage.
• 160–260 V AC input range – designed to operate within the specified input voltage limits.
• 230 V AC rated output voltage – for single-phase electrical and electronic equipment.
• ±3 % regulation accuracy – for more precise output voltage control.
• Servo motor regulation system – provides smooth automatic voltage correction.
• Copper transformer winding – used in the transformer construction of the stabilizer.
• LCD display – for monitoring input and output voltage, current, load level, and operating status.
• Overvoltage and undervoltage protection – helps protect connected equipment when the voltage exceeds the permitted limits.
• Overload protection – specified activation threshold of approximately 120 % of rated load.
• Overheating protection – specified protection temperature of approximately 80 °C.
• Integrated MCB – for disconnecting the circuit in the event of a short circuit.
• Approx. 8-second power-on delay – the output is not switched on immediately after power is restored.
• Ventilation openings in the housing – for heat dissipation.
• Wall-mounted design – allows vertical installation without occupying floor space.

• Televisions and audio equipment – where mains voltage fluctuations occur.
• Computers, monitors, and workstations – for equipment of suitable power requiring a more stable supply voltage.
• Routers and communication equipment – for continuous operation in unstable electrical networks.
• Security and video surveillance systems – for powering cameras, controllers, and recording equipment of suitable power.
• Low- and medium-power household appliances – provided their rated and starting power does not exceed the stabilizer's capabilities.
• Refrigerators and freezers – after checking the starting power of the specific compressor.
• Small pumps, fans, and motors – when their starting current has been checked and sufficient power reserve is provided.
• Several lower-power appliances – when their combined load does not exceed the stabilizer's capabilities.
• Offices and commercial premises – for electronic, communication, and control equipment.
• Private houses and country homes – where mains voltage fluctuations occur more frequently.
• Control and automation equipment – where a more stable 230 V AC supply voltage is required.

For example, in a private house the mains voltage periodically fluctuates but remains within the stabilizer's 160–260 V AC input range. Suitable-power electronic, communication, household, or other single-phase equipment is connected to the stabilizer.

The stabilizer measures the input voltage and automatically adjusts the transformer regulation position using the servo motor. The LCD display allows monitoring of input and output voltage, current, and load level.

If an overload, short circuit, overheating, or voltage outside the permitted operating limits occurs, the integrated protection systems are designed to disconnect the output and reduce the risk of damage to connected equipment.

For home users: suitable for electronics and household equipment of appropriate power when the mains voltage is unstable.

For office users: can be used for computers, communication equipment, and other electronic equipment without exceeding the permitted load.

For maintenance technicians: the LCD display allows monitoring of input and output voltage, current, and load level.

For installers: the mounting location must be properly selected, the approximately 15 kg product weight taken into account, sufficient ventilation space provided, and the rated and starting power of the connected equipment checked.

The stabilizer is designed for wall mounting. The mounting surface and fastening elements must be selected considering the device weight of approximately 15 kg.

• Check the electrical network parameters and manufacturer's wiring diagram before connection.
• Do not exceed the rated power of 3 kVA.
• Take into account the power factor, starting power, and starting current of the connected equipment.
• Provide additional power reserve when the input voltage is low.
• Do not cover the ventilation openings in the housing.
• Leave sufficient space around the device for heat dissipation.
• Protect the device from moisture and condensation.
• Protect it from strong heat sources and direct adverse environmental effects.
• Use a suitable Schuko / EU type connection.
• The device must be properly grounded in accordance with applicable electrical installation requirements.
• Permanent electrical connection must be carried out by a qualified specialist.

Quick selection guide

Choose the 3 kVA voltage stabilizer when suitable-power single-phase electronic, household, communication, or control equipment needs to be supplied with a more stable 230 V AC voltage and the mains voltage falls within the specified 160–260 V AC regulation range.

Automatic 230 V voltage stabilization for single-phase electrical equipment

The wall-mounted automatic 3 kVA voltage stabilizer is designed for single-phase electrical consumers when the mains voltage is unstable and automatic regulation is required.

The servo motor-controlled system, 160–260 V AC input range, 230 V AC rated output voltage, ±3 % regulation accuracy, copper transformer winding, and LCD display allow the main power parameters to be monitored and automatically regulated.

Integrated protection systems and the wall-mounted design complement the functionality of the device. Before selecting the stabilizer, however, it is essential to correctly assess the rated and starting power of the connected equipment, its power factor, and provide sufficient power reserve – especially for equipment equipped with electric motors or compressors.
