Shield compact transformer I1820 with secondary current of 1 and is designed to transform the current measurement current, power, power factor and small-size panel meter type E140, D142 and E144.
I1820 transformers with secondary current 0.3 and used as an intermediate in the CT to include panelboard ammeters, wattmeters, varmeter phase meters and at a distance from power current transformers with secondary current 5A.
Transformer is used at an ambient temperature of -40 to +60 ° C and relative humidity of 98%. Not operate a transformer at a temperature of -50 to +60 ° C and relative humidity up to 95%.
In terms of resistance to mechanical stress CT refers to a jolting, vibration-and shock-resistant.
Rated transformer data are shown in Table.
