The SERVO CONTROLLED VOLTAGE STABILIZER utilizes a motor driven variable auto transformer & a Buck\Boost transformer, which is connected between the incoming phase supply & the load. The primary winding of the Buck\Boost transformer is connected to the continuously Variable Auto Transformer in such a way that one lead of the winding is connected to a predetermined tap point of the auto transformer, depending on the position of the variable brush arm with respect to the fixed point the voltage applied to the primary winding has addition or subtraction on the supply voltage available on the secondary side.The autotransformer is driven by an AC synchronous motor to achieve increase or decrease in output set voltage by rotating it in clockwise or anticlockwise direction depending on the input supply voltage.An electronic control card continuously monitors the output voltage and the same is being compared against the set reference voltage to achieve the desired output voltage. The control card responds to the variation in input voltage in such a way that the motor in voltage correction doesn't overshoot in either direction. This method of correction in output voltage is free from generating waveform distortion & harmonics.   Features: Fast corrections rate and very high efficiency. Works over wide input frequency range and no waveform distortion. Specially designed high performance I.C. based control circuit for ultra high reliability. Auto/Manual operation facility. Over voltage and under voltage Indicators. Output voltage adjustability provided on panel. Unaffected by load Power Factor Plug -in type glass-epoxy control cards for easy on line serviceability. All components used are of reputed makes confirming to relevant IS/BS standards. Stabilizer are subject to routine and type tests in accordance with latest IS Standards (IS:9815-94)   Advantages: Automatically corrects voltage on regular intervals. When supplied with constant voltage, synchronous motors operate highly efficiently. Protects expensive electrical equipments from menace of voltage fluctuation thus lowers the cost on maintenance. Better efficiency in plant with less production losses. 100% depreciation as per Income Tax Act. Reduces the electricity bills approximately up to 15% As the generator is not required to run at High/Low input voltage thus it saves on diesel cost. The average pay back period of Servo Controlled Voltage Stabilizer owing to its high energy saving capability, which is approx. 18 months.   Field of Application : Air Conditioning Plants Medical Equipment Offset Printing Machine C.N.C. Machines Escalators & Elevators Mall & Commercial Complex Residences & Offices Telecommunication System Farm House Defense Equipment Information Technology Call Centers Cement Plants Domestics load Hotels Textiles Industries Pharmaceutical Industries R & D Institutions Metrological Department Induction Heating Plant

Output of An isolation transformer is totally isolated from input. Any fault, leakage, Electrical noise, voltage transients, spikes etc. in the input side because of other loads connected in parallel are not reflected on the output, thus avoiding damage to sensitive electrical equipmentIsolation Transformer are available as open type as well as metal enclosure. We are also MANUFACTURING Transformer of different type and capacities to suite INDIVIDUAL requirement. Single phase and three phase, auto double wound, air/oil cooled. We have enough capacity to serve DIVERSIFIED CUSTOMERS and heavy volume requirement of Transformer. We are well equipped with plant & machinery to supply good quantity orders on committed time.

optimum performance of sophisticated electronic equipment is highly dependent on the stability of the mains voltage. The continuously fluctuating mains supply, transients, spikes & surges produce harmful effects.the cvts are preferred over voltage stabilizer as the stabilizer have relays that are when switched cause the output voltage to be interrupted for a short time. This type of interruption or transient many not be good for computers. In comparison to voltage stabilizer, the cvts ensure a clean, spike-free and controlled output voltage.'bluebird' constant voltage transformer gives an effective solutions to all these problems.constant voltage transformer are based on ferro-resonance principle & it consists of two basic components i.e. Ferro-resonant transformer and capacitor.   salient features: high reliability as no semi conductors/moving parts used. provide relatively sine wave output irrespective of quality of input wave shape. instantaneous voltage regulation. output highly isolated from mains for suppression of transients & spikes. short-term over load capacity. intrinsic current limiting & short circuit protection. higher input voltage control range for loads less than rated load.   recommendations: place the cvt away from equipment and all magnetic display and storage devices like diskettes, monitors, tapes etc. it is safer to connect cvt to mains supply through a 3 pin socket ensuring thereby the availibility of proper 'earth' connection. switch on the cvt first then the attached peripherals and while switching off, switch off attached peripheerals first and then the cvt. in case of supply from a generator, check frequency, cvt is not be used if frequency variation is beyond 50 +/-1hz. switch off the cvt when not in use. not to be used for high inductive loads like motors.
