Analog Constant Voltage Transformer
We are offering Constant Voltage Transformer to our clients that is widely used in several industries to provide constant electrical power to the appliances. The voltage transformer is an electrical instrument that set up or step down the voltage level. Transformers work based on the Faraday's law of induction. Our offered Constant Voltage Transformer is a durable and very functional product. It is assembled using top grade electronic components, therefore, a long service life of the transformer is ensured.
In Hi-Rel 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.
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)
Hi-Rel CVT is available in a wide range.. from 100VA to 5000 VA with load test conducted at unity power factor for all ratings.
