We offer Servo Voltage Stabilizers that help in solving voltage fluctuation problems by their unique automatic voltage correction, power protection & surge protection. These servo voltage stabilizers help in saving electrical appliances from high and low voltage. The rating of these Stabilizers can vary from 2 KVA to 25 KVA (I/P) to 6 KVA to 2000 KVA (III/P). It has a wide Input range varying from 140V – 280 V (Single Phase) to 240 V- 485 V (Three Phase). The Output range also varies from 230V (Single Phase) to 400V (Three Phase). It has a high accuracy and varying frequency can be measured in the range of 47Hz-53Hz (Single Phase & Three Phase). It has no power factor effect and wave form. It is digitally controlled and response time is less than 10 ms. It also has a high correction rate of 15V-40V/Sec and a digital analogue display. The highlight of this product is that it has a Log Book with a non- volatile memory and has several programmable features which include a time delay set with a HV/LV cut- off set. It can be operated in an auto or manual mode and is easily air or oil cooled. It also has an automatic protection switch off against under/ over voltage, overload/ short circuit, single phasing, surge protection and also against lightning protection. It efficiency is as high as 97%. Our stabilizers are used in various Industries like Rice & Flour Mills, Hospitals, Airlines and many more.
