Current-voltage transformer, which is actually the primary and secondary turns ratio of 1:1 of the current transformer, used be in the primary series with current-limiting resistors, input and output are for mA-class current, input voltage can not be directly imposed on the primary winding is required into the current-limiting resistor string voltage signal is converted to mA-level currents, sub-mA level output current signal through a resistor or external parallel I / V converter circuit will replace the current signal voltage sub - Rated primary current:2mA Rated second current:2mA Ratio:1000:1000 2000:2000 Primary current range:0 120% Phase error (rated input):<15' Linearty:0.1% Accuracy calss:0.2 0.1 Dielectric withstanding voltage(hi-pot):3000Vrms Typical application:used in electronic electric energy meters and electric testing equipment Cup:PBT Encapsutant:epoxy Ambient temp:-40 +70
