Three-phase AC current transducer coal power station where perforation phase current transducer Specifications Picture DC current transducer current transmitter points and two kinds of three-phase AC current transducer AC current transducer is a three-phase alternating current grid isolating transmission means into a linear DC analog signal. Three-phase three-wire three-phase four-wire with two functions and applications of the three-phase AC current transducer. Current transducer is a three-phase alternating current power grid linear transmission of DC isolated analog signal. A remote device, the computer inspection, automation and control necessary to capture analog input section can be widely used in power systems, industrial control, building systems and other industrial coal mining enterprises and other technical parameters: Operating temperature -10 ℃ ~ 55 ℃ Storage Temperature -25 ℃ ~ 70 ℃ Relative humidity ≤90% RH, non-condensing, non-corrosive gases Altitude ≤2500m input signal AC 0 ~ 1A, 0 ~ 5A continuous current overload 1.2 times the instantaneous current 10 times / 1 sec frequency 45Hz ~ 65Hz Output DC 4 ~ 20mA, 0 ~ 20mA, 0 ~ 5V, 0 ~ 10V output load current ≤600Ω, operating supply voltage output ≥1000Ω AC 85V ~ 265V or DC 100V ~ 350V Temperature drift accuracy class 0.5 When the level ≤200ppm / ℃, when accuracy rating for 0.2 ≤100ppm / ℃ Insulation resistance ≥100MΩ response time isolator response time <400ms current transducer installation using standard 35mm rail mounting or with screws Example: Input : AC 0 ~ 1A Output: DC 4-20mA Accuracy: 0.2 Auxiliary Power: AC220V / 50Hz Input: AC 0 ~ 5A Output: DC 4 ~ 20mA Accuracy: 0.5 Auxiliary Power: DC220V
