Qoltec AVR Automatic Voltage Stabilizer, 3000VA, 1800W, Toroidal Transformer, Compact

Safe and stable operation

Protect your devices – discover the benefits of the Qoltec automatic voltage stabilizer

Ensures stable and safe power supply for home and office devices, providing complete protection for electronic equipment against overvoltage, overloads, and short circuits. The Qoltec AVR 3000VA / 1800W automatic voltage stabilizer is a reliable solution that protects your equipment from the effects of voltage fluctuations, overloads, and short circuits. Thanks to precise input voltage regulation, the device ensures optimal operating conditions for computers, televisions, audio equipment, refrigerators, pumps, and many other electrical appliances.

Protect your device

Stable 230V output regardless of fluctuations, specialized short-circuit protection, toroidal transformer

By choosing our solution, you get:

• Voltage stabilization in the 125–270V AC range, ideal for home and office use
• Automatic voltage boost or buck for a stable 220–240V AC output
• Rated power of 1800W (3000VA) – suitable for most electronic devices
• Toroidal transformer – the round core reduces energy losses and heat dissipation, allowing the stabilizer to operate efficiently and reliably even under heavy loads
• Delayed start function (6 s / 180 s) – protects compressors and motors from damage caused by frequent restarts
• Multi-level protection: against overvoltage, undervoltage, overload, overheating, and short circuits
• High efficiency of 95% and reduced voltage distortion (<3%)
• Silent operation – noise level below 65 dB
• Dual digital LED display – shows input and output voltage simultaneously
• Compact and robust construction, with wall-mounting option

The toroidal transformer – the heart of the device

Toroidal transformer – low losses, high energy efficiency, resistance to overheating

The stabilizer features an efficient toroidal transformer that ensures efficient and silent operation of the device. The round core reduces energy losses and heat dissipation, so the equipment operates stably and without interruptions even under heavy loads.

Benefits of the toroidal transformer:

• high energy efficiency,
• low power losses,
• silent operation,
• resistance to overheating.

Intelligent start delay – protection for your appliances

Default delay time of 6 seconds, maximum 180 seconds

The stabilizer has a delayed start function. This function is useful for appliances with motors and compressors, protecting them from damage caused by frequent restarts immediately after shutdown. The default delay time is 6 seconds, but it can be extended to up to 180 seconds if needed.

Full control thanks to the convenient LED display

Clear display of main operating parameters

The stabilizer features a convenient dual LED display, allowing you to easily monitor and read the main operating parameters: current output voltage, information about any overvoltages, the delay time (if active), and other important parameters. This makes it easier to monitor its operation and gives you the certainty that everything is working correctly and as expected.

Mobility and reliability wherever you are

Compact design, solid metal construction

Thanks to its compact design and solid metal construction, the stabilizer is the perfect travel companion and a convenient solution anywhere. At home, in the office, or on the go, you can easily take it with you and have stable voltage wherever you need it.

Benefits of the metal casing:

• high resistance to impacts and scratches,
• effective protection of internal components,
• better heat dissipation,
• aesthetic, professional appearance,
• increased durability of the entire structure.

Everything included – mounting anchors and screws

Convenient wall mounting – solid construction, secure hold

The Qoltec stabilizer is designed for easy and secure wall mounting. The back panel of the casing features special mounting holes in a keyhole shape, allowing for quick hanging of the device. The set includes anchors and screws, so installation is simple, stable, and requires no additional accessories.
