ITFrequently Asked Questions · AVR
What warranty do automatic voltage stabilizers (AVR) come with?
AVRs are covered by a 24-month warranty, with the warranty registration form completed within 10 days of purchase and a copy of the invoice. Otherwise, the warranty starts from the date of sale.
The service life of an AVR depends mainly on whether it was chosen with enough power and whether it operates in a suitable environment. For the warranty, fill in the form within 10 days of purchase and keep a copy of the invoice; otherwise, the start date is calculated from the date of sale.
Many stabiliser problems stem from the conditions of use. An AVR that runs permanently close to its power limit, or feeds motors with high inrush current without headroom, overheats. The same happens when it is installed in a closed cupboard without ventilation or in a humid, dusty room. Servo-type stabilisers also have moving parts that benefit from periodic inspection.
As a practical rule, size the AVR with a good margin above the total consumption, and an even larger one when refrigerators, air conditioners or pumps are involved. Large units connected to the electrical panel must be installed by an electrician.
If you notice an unusual hum, a burning smell or frequent output cut-outs, stop using it and contact support. Do not open the unit yourself.
