We are engaged in the manufacturing of constant voltage transformer that finds wide application in domestic market. The AC mains supply adequately powers input winding, which in turn is physically separated from the isolated o/p winding. The input winding normally runs at very moderate flux linkage level. The output winding in conjunction with the mains capacitor exhibits a built-in energy storage characteristic, which results in self-generated AC flux field, which is indirectly excited, from the input winding. The constant voltage transformer is provided with intrinsic filter that protects system from spikes & surges on the AC mains lines. The filter operates in the transverse as well as common mode, offering complete protection.

Why Lift Inverter?
 

Type	Static Electronics Device	Electro-mechanical Device
Cost	Is more economical than Generator.	Is costly than ELOS.
Extra cost	No additional circuitry, acoustic covering (canopy) & hidden costs.	Require AMF panels, acoustic covering etc.
No load Condition	Utility of battery power is only during operation of the load.	Generator is required to be kept ON in NO LOAD condition also, hence un-necessary usage of fuel.
Noise	Absolutely Noiseless	Very noisy.
Changeover Time	Auto changeover within few milliseconds.	Has to start manually.
Recurring Cost	Negligible if maintained properly	Fuel(diesel) & maintenance cost is more because of wear and tear due to internal rotary mechanical parts.
Life	Life of equipment is more than Generator. Batteries can last for 3 to 5 years if maintained periodically.	Lesser than Life inverter . If extended, the expense of alternator and other spares replacement is considerable.
Pollution	Absolutely pollution free & environmental friendly	Emits smoke, fumes & noise
