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

Wall-Mounted Automatic Voltage Stabilizer – 1.5 kVA, 230 V, Servo Drive, Copper Winding, LCD

Single-phase wall-mounted automatic voltage stabilizer is designed to supply electrical equipment with a 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 – the stabilizer is 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 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 protection threshold is approximately 120 % of rated load.
• Overheating protection – specified protection temperature is approximately 80 °C.
• Integrated MCB – for disconnecting the circuit in case of a short circuit.
• Approx. 8-second switch-on delay – the output is not switched on immediately after power is restored.
• Ventilation openings in the enclosure – for heat dissipation.
• Wall-mounted design – allows vertical installation without occupying floor space.

• Televisions and audio equipment – where mains voltage fluctuations occur.
• Computers and monitors – for equipment of suitable power requiring a more stable supply voltage.
• Routers and communication equipment – for continuous operation in an unstable electrical network.
• Security and video surveillance systems – for powering cameras, controllers, and recording equipment of suitable power.
• Low- and medium-power household equipment – when rated and starting power does not exceed the stabilizer's capabilities.
• Small refrigerators and compressor equipment – only after evaluating the specific starting power.
• Small pumps and electric motors – after checking their starting current and ensuring sufficient power reserve.
• Office equipment – for computers, communication equipment, and other electronic equipment of suitable power.
• Private homes and country houses – where mains voltage fluctuates 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 single-phase electronic, communication, or other equipment with an appropriate total load is connected to the stabilizer.

The stabilizer measures the input voltage and automatically adjusts the transformer's 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 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 selected appropriately, the approximate 15 kg product weight must be taken into account, sufficient ventilation space must be provided, and the rated and starting power of the connected equipment must be 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.

• Before connection, check the electrical network parameters and the manufacturer's wiring diagram.
• Do not exceed the rated power of 1.5 kVA.
• Consider the power factor, starting power, and starting current of the connected equipment.
• At low input voltage, provide additional power reserve.
• 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 the device from strong heat sources and direct adverse environmental exposure.
• Use a suitable Schuko / EU 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 1.5 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 1.5 kVA voltage stabilizer is designed for single-phase electrical loads when mains voltage is unstable and automatic voltage 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 device's functionality. However, before selecting the stabilizer, it is essential to correctly evaluate the rated and starting power of the connected equipment, its power factor, and provide sufficient power reserve – especially when using motor-driven or compressor equipment.
