Vijayshree equipments make servo voltage stabilizers are designed to give stabilized output voltage within ±1%. Solid-state control with brushless ac synchronous motor and buck boost transformers ensure fault free operation in extreme voltage fluctuating conditions. With precision high voltage and low voltage cut out circuit with power contractor and overload protection by mccb, power on delay with automatic restart facility in case of power failure. Various models are available, fully oil cooled type, fully air cooled type, with various output voltages as per requirement, 415, 400, 380, 220 v phase to phase with input voltage range from 360-460 v phase to phase, to 290-480 v phase to phase with a stable output voltage. Power ratings are available form 3-500 kva 3-phase and 1-25 kva 1 phase quality and testing standards conforms to is 9815-1981.
