Certain critical Equipment, especially Medical Equipment, require Solid State Voltage Stabilizers with Galvanic Isolation between Mains Input and Equipment. Also the Equipment needs to be protected against spikes, voltage, surges, glitches, noise, etc. which is not possible with conventional Servo Voltage Controlled Stabilizers.   A special type of Stabilizer, called C.V.T (Constant Voltage Stabilizer) is used for such applications. A CVT works on magnetic saturation principle, resonating with a tank circuit of High Q factor. When incoming Mains Voltage is low the capacitor provides the necessary additional gain in power, keeping the output voltage steady. On the other hand, when the Mains Voltage is high the leakage reactance drops the difference of voltage. This correction of voltage is instantaneous even for sudden dips and spikes.

• Output Voltage: 220 — 230V ± 1%

Makvolt Power Constant Voltage Transformers (CVTs) are AC Voltage Stabilizers providing steady voltage to electrical equipmentinstruments and protecting them from the harmful effects of under-voltage and over-voltage. Makvolt ferroresonant CVTs are the ideal maintenance free solutions for loads that can suffer erratic operation or be damaged by electrical noise (common and series mode) local transients, mains power sags, surges and brownouts.

There are times when one feels that a stabilizer is not enough. After all, a stabilizer can correct voltage with a certain finite speed. We would think that our instruments are connected to a stabilizer and are unaware of the fact that it is stilt passing on the spikes, voltage surges, glitches, noise etc. Which are so short, that it cannot be corrected by a stabilizer. What then? The answer is a C.V.T. from 'ASEEM-OORJA'® This works on magnetic saturation principle, resonating with a tank circuit of high Q factor. When incoming Mains voltage is low the capacitor provides the necessary additional gain in power, keeping the output voltage steady. On the other hand , when the mains voltage is high the leakage reactance drops the difference of voltage. This correction of voltage is instantaneous even for sudden dips and spikes.Capacities Available from 1.0 KVA to 10.0 KVA.Ask for Custom Built CVT.

In an Elent CVT, the AC mains powers the input winding which is widely separated physically from the isolated output winding. The input winding normally runs at very moderate Flux linkage levels. The output winding exhibits an intrinsic energy characteristic and this energy storage operates in conjunction with mains capacitor to produce self-generated AC flux field which is indirectly excited from the input winding. The result is instantaneous voltage regulation. No transient and spikes. Sinewave output. A perfect answer and remedy for every electronic equipment. SALIENT FEATURES No semiconductors or moving parts used, hence very high reliability No feedback control used Intrinsic current limiting and short circuit protection Output voltage correction within ½ Cycle ( 10 ms) from no load to full load for specified load and line variation Short term over load capability Energy storage for line loss up to 3 ms at typical loads Higher input voltage control range, for loads less than rated load Very high line transient/spike rejection capability and excellent input to output isolation characteristics Output floating (optional) Range Elent CVT is available in a wide range.. from 50 VA to 10,000 VA with load test conducted at unity power factor for all ratings.

We are offering constant voltage transformer. uhi series of shepherd cvt's , being produced are designed to additionally address itself to such line disturbances and provide better all round performance. Besides, of course, providing sufficient degree of output voltage regulation against random changes in the input voltage and load etc. Salient features of the uhi (ultra high isolation) series cvt are as under. less effect of variation in line frequency on the output set voltage as brought down to 1.27% from 1.40%. enhanced power against momentary overloads. units are inherently protected against failure on account of short circuit of op. instant response & correction of voltage. the cvt (ferro) uses the unique principle of ferro resonance: operation of a transformer in the region of magnetic saturation. When the iron core of a transformer is in saturation, relatively large changes in winding current results in very small changes in magnetic flux. Winding current and magnetic flux are proportional to the input and output voltage, respectively. This means that relatively large changes in input voltage result in small changes in output voltage: this being the fundamental purpose of an automatic voltage regulator. additionally, the ferro voltage regulator, by its unique design, provides good isolation of load equipment from line noise and surges. The output voltage regulation is also smooth so long as the manufacturer has taken steps to minimize the distortion that is caused by operation in the saturation region. Ferro voltage regulators can be very durable with some manufacturers offering warranties in excess of 10 years. one unusual operating characteristic of the ferro voltage regulator is that its design can limit the amount of current to the load. When is load current exceeds about 150% of rated current of a ferro voltage regulator, the unit is “pulled” out of the saturation region, the output voltage collapses to a very small value and the current is thereby limited.
