Servo Controlled Voltage Stabilisers

Professional Lighting Pvt Ltd manufactures servo controlled voltage stabilisers for use with equipment that is sensitive to fluctuations in line voltage. These stabilisers are housed in compact cabinets. The built-in voltmeter with high resolution gives the measurement of both the input and output voltages. AC synchronous motor without carbon brushes is provided for automatic operation. Reset push button is incorporated for tripping under/over voltages. These ACE voltage stabilisers are insensitive to the magnitude and power factor of the load and do not affect the system power factor. Wide frequency range, spike protection, fast correction rate, AC fuse protection, low internal impedance and high efficiency are the other important features. Solid-state voltage sensing circuit with auto/manual operation facility is provided for powers above 2 KVA. Applications: computers, word processors, electronic typewriters, photocopiers, laboratories, process-controlled equipment, CNC machines, EPABX and telecommunications.
