Cotton Constant Voltage And Constant Current Transformers

With the rich experience in market, we manufacture, export and supply a extensive range of Constant Voltage And Constant Current Transformers in Hyderabad, Telangana, India. Low losses with higher saturation flux suitable shunt adjustments in design and practice gives the required constant voltage output at designated tap. Correction is almost instant (static). - See more at: http://emagdevices.com/product/constant-voltage-and-constant-current-transformers.
These transformers work under magnetic saturation and resonating principals at the mains frequency.This is done by suitable leakage inductance and Ac capacitor. Saturation effect results in distortions and which is compensated with a series inductor to get sine wave within 5% distortions.The leakage inductance helps in current limiting in event of short circuit. The output voltage regulation is within 2% for input variation 70 to 120% voltage output 0 to 100% load. Because of current limit features not recommended for high inductive loads (Motors).The saturation of core results in higher no load losses hence poor efficiency at less than 25% load.Without capacitance which can work current limiting suitable for constant current mode. Range: 100 VA to 5KVA dry type Frequency: 50/60/400Hz Phase: F Single Phase, 3 Phase Terminals: Flying Leads or Barrier type shrouded studded lugs Enclosure: Open type IP00 or with enclosure Primary V : 50 to 1200V, Secondary: 1V to 1200V.
