Toroidal transformer – the heart of the device

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:

✔ high energy efficiency,

✔ low power losses,

✔ quiet operation,

✔ resistance to overheating.

Smart start delay – protecting your appliances

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.

Full control thanks to a convenient LED display

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. 

Mobility and reliability wherever you are

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:

✔ high resistance to impact and scratches,

✔ effective protection of internal components,

✔ better heat dissipation,

✔ aesthetic, professional appearance,

✔ increased durability of the entire structure.

Everything included – mounting pegs and screws included

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.
