Dubas manufacturers a wide range of K-Rated Isolation Transformers for protecting the loads from various type of power problems like electrical noises, harmonics, spikes etc., Many of the loads are of non-linear type and create high distortions in the current waveforms. These distortions are essentially deviations of the waveforms from the fundamental waveform caused due to the superimposition of a number of sinusoidal waveforms whose frequencies are multiples of the fundamental frequency (50Hz). Harmonics generate higher heat in the transformer. A transformer built to handle these harmonic currents is rated by K factor. K factor isolation transformers can handle these harmonic currents without exceeding the specified temperature rise levels. Typically, K-13 transformers are employed in many applications.

Dubas Isolation Transformers and K-rated transformers (K4, K7, K13 and K20) are ideal solution for safeguarding various kinds of loads from majority of power problems.
