Current-voltage transducers AC/AC
Current-voltage transducers transform primary alternating curent to secondary alternating voltage withe accuracy class 0.5 or 1. They are designed for supplying measuring and protective circuits of electrical power devices.
Transducers conform with PN-EN 60044-1 standards (without transducers IU type):
- with accuracy class 0.5 and 1 in range from 5% to 120% rated primary current
- with accuracy class 3 in range from 50% to 120% rated primary current
Transducers current-voltage EULA 0 type with primary current 5 A or 1 A can be used in secondary circiut of current transformers changing current signal on voltage signal.
Advantage of our transducers is rated short-time thermal current (1 sec): Ith = 60 * Ipn.
Secondary circuit of current-voltage transducers can be open or shorted.
Also can be loaded the larger resistance than passes in technical data.
