Digital | Automatic Voltage Stabilizer for Electrical Network | 1P | 5kVA | 160-260VAC | 230V

Wall-Mounted Automatic Voltage Stabilizer – 5 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, a copper transformer winding, a digital LCD display, and integrated protection against overvoltage, undervoltage, overload, overheating, and short circuit.

• Automatic voltage stabilization – adjusts 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 regulation.
• Servo motor regulation system – for smooth automatic voltage adjustment.
• Copper transformer winding – used in the stabilizer transformer construction.
• 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 permitted limits.
• Overload protection – specified activation threshold of approximately 120 % of rated load.
• Overheating protection – specified protection temperature of approximately 80 °C.
• Integrated MCB – disconnects the circuit in the event of a short circuit.
• Approx. 8-second power-on delay – the output is not activated immediately after power is restored.
• Ventilation openings in the enclosure – for heat dissipation.
• Wall-mounted installation – allows vertical mounting while saving floor space.

• TVs and audio equipment – when mains voltage fluctuations occur.
• Computers, monitors and workstations – for equipment of suitable power requiring more stable supply voltage.
• Servers, communication and network equipment – for long-term operation in an unstable electrical network.
• Household appliances – when the total rated and starting power does not exceed the stabilizer's capabilities.
• Refrigerators and freezers – only after evaluating the starting power of the specific compressor.
• Small air conditioners – only after checking their rated power and compressor starting current.
• Pumps, fans and small motors – when sufficient starting power reserve is available.
• Several electrical appliances simultaneously – when their total load does not exceed the stabilizer's capabilities.
• Offices and commercial premises – for electronic, communication, security and control equipment.
• Private houses and country homes – in locations where mains voltage fluctuates more frequently.
• Control, automation and technical equipment – when 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. Household electronics, computer or communication equipment and several electrical consumers of suitable power are 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 range occurs, the integrated protection is designed to disconnect the output and reduce the risk of damage to connected equipment.

For home users: suitable for electronics, household appliances and several electrical devices when the mains voltage is unstable.

For offices or commercial premises: can be used for computers, communication, security, cash register and other electronic equipment without exceeding the total 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 selected appropriately, the product weight of approximately 15 kg must be considered, sufficient ventilation space must be provided, and the total rated and starting power of the connected equipment must be checked.

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

• Check the electrical network parameters and the manufacturer's wiring diagram before connection.
• Do not exceed the 5 kVA rated power.
• Consider the power factor, starting power and current of the connected equipment.
• When connecting several devices, consider their total load.
• Provide additional power reserve when the input voltage is low.
• Do not cover the ventilation openings in the enclosure.
• 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 5 kVA voltage stabilizer when you need to supply suitable single-phase household, electronic, communication, control or technical equipment with a more stable 230 V AC voltage, while the mains voltage remains within the specified 160–260 V AC regulation range.

Automatic 230 V voltage stabilization for higher single-phase loads

The wall-mounted 5 kVA automatic voltage stabilizer is designed for single-phase electrical consumers when the mains voltage is unstable and automatic voltage regulation is required.

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

The 5 kVA rated power provides greater possibilities for supplying several consumers or higher-power single-phase equipment. However, before selection, it is necessary to accurately assess the total rated and starting load, power factor and provide sufficient power reserve.
