Qoltec Automatic Voltage Stabilizer AVR 1000VA | Compact | Toroidal transformer

Protect your devices – discover the advantages of the Qoltec automatic voltage stabiliser

Ensure a stable and safe power supply for your home and office devices and full protection of your electronic equipment against the effects of power surges, overloads and short circuits. The Qoltec AVR 1000VA / 600W automatic voltage stabiliser is a reliable solution that protects your equipment against 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.

Stable 230V voltage regardless of fluctuations, specialised short-circuit protection, toroidal transformer

By choosing our solution, we offer:
- Voltage stabilisation in the range of 125–270V AC, ideal for home and office applications
- Automatic voltage increase or decrease to maintain a stable 220–240V AC output
- Rated power 600W (1000VA) – suitable for most electronic devices
- Toroidal transformer – round core minimises energy loss and heat emission, allowing the stabiliser to operate efficiently and reliably even under heavy loads
- Delayed start function (6s / 180s) – protects compressors and motors from damage during frequent switching on
- Multi-stage protection: against overvoltage, undervoltage, overload, overheating and short circuit
- High efficiency of 95% and low voltage distortion (<3%)
- Quiet operation – noise level below 65 dB
- Dual LED digital display – shows input and output voltage simultaneously
- Wall-mountable, compact and robust design

Toroidal transformer – Low power losses, high energy efficiency, resistance to overheating

The stabiliser is equipped with an efficient toroidal transformer, which ensures effective and quiet operation of the device. Its round core minimises energy losses and heat emission, allowing the equipment to operate stably and without interference even under heavy loads.

Advantages of a toroidal transformer:

Default delay time 6 seconds, maximum up to 180 seconds

The stabiliser is equipped with a delayed start function. The default delay time is 6 seconds. This function is useful for products with motors and compressors to prevent and protect the device from damage due to frequent switching on immediately after switching off. The default delay time is 6 seconds, but it can be extended up to 180 seconds if necessary.

Clear presentation of key operating parameters of the device

Our stabiliser is equipped with a convenient dual LED display that allows for easy monitoring and reading of key operating parameters. It provides a clear presentation of data such as current output voltage, information about possible surges, delay time (if active), and other important operating parameters. This not only facilitates monitoring of the device's operation, but also gives the user confidence that everything is working properly and as expected. 

Compact design, sturdy metal construction

Thanks to its compact design and solid metal construction, our stabiliser is the perfect travel companion and a convenient solution for any location. Whether you are at home, in the office or on the go, you can easily take our device with you, ensuring stable voltage wherever you need it.

Advantages of the metal housing:

Convenient wall mounting – solid construction, secure support

The Qoltec stabiliser has been designed for easy and safe wall mounting. There are special mounting holes in a key pattern on the rear panel of the housing, which allow the device to be hung quickly. The set includes mounting plugs and screws, making installation simple, stable and requiring no additional accessories.
