Other Details -

Constant Voltage Transformers effectively regulate voltage variation, suppresses transients and bridge short interruptions. We manufacture these transformers using high quality materials and components at our sound production unit. These transformers are known for features like low local discharge, low loss, low noise, high reliability and protection against abrupt short circuit. Clients can obtain these transformers in different technical specifications from us. In home appliances and computers these transformers are highly utilized. We offer these transformers at market leading prices to clients.

In a purevolt CVT, the AC mains powers the input winding. Which 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 storage characteristic and this energy storage operates in conjunction with mains capacitor to produce self-generated AC flux field with is indirectly excited from the input winding.

Salient Features:

  • No semiconductor or moving part used, hence very high reliability.
  • No feed back control used.
  • Intrinsic current limiting and short circuit protection.
  • Energy storage for line lose up to 3 ms at typical load.
  • Short term over load capacity.
  • Higher input voltage control range for load less than rated low.
