Converters AC/DC - current-voltage converter

Current-voltage converters AC/DC

Current-voltage converters AC/DC transform primary alternating current I_pn to rated secondary direct voltage U_sn. They are designed for supplying measuring and protective circuits of electrical power devices.

Current converters transform alternating primary current up to 120% value with accuracy ± 3% in range from 20% to 120%.

Advantage of our current transformers is rated short-time thermal current (1 second): I_th = 60 * I_pn.
The secondary circuit of current-voltage converter should be loaded according to technical data or should be opened.
