HT-AVR or High Tension-Automatic Voltage Regulators are the high-tension stabilizers that protect electrical equipment from irregularities of voltage. These voltage regulators supply a continuous and stable input voltage. We are involved in manufacturing a wide range of HT-Automatic Voltage Regulators.

HT-AVR are used to get stable input voltage, irrespective of the voltage received from electricity authorities. These regulators not only prevent electrical equipment from fluctuating and irregular Voltages but also the transformer and thus increasing its life and efficiency.

A Built in AVR is a combined unit of HT AVR and Step Down Transformer. Together it gives you stabilized LV output even when the HT voltage input is.
