Precision-engineered servo voltage stabilizers — air cooled and oil cooled — available from 1KVA to 500KVA for every application.
Designed for residential and light commercial applications. The servo-motorized variac mechanism provides precise output voltage regardless of fluctuating input, protecting appliances and equipment from damage.
Ideal for commercial establishments, hotels, hospitals, small industries, and medium-scale manufacturing plants. Delivers balanced three-phase output with precision voltage correction across all phases simultaneously.
Purpose-built for heavy-duty industrial use — textile mills, chemical plants, large factories, and high-demand facilities. Oil cooling allows continuous operation at high loads without performance degradation. Preferred over air cooled above 50 KVA to reduce fire hazard.
