Current Transducer
Product ID: NA50-P

Applications: For the electronic measurement of currents: AC, DC IMPL.,etc.,with galvanic isolation between the primary (high power) and the secondary (electronic) circuits. Main technical data: 1. Primary normal current I_PN: 50A r.m.s 2. Primary current, measuring range I_P: 0~+/-70A 3. Measuring resistance: R_Mmin R_Mmax with +/-12V @ +/-50A max: 10 ohm 95 ohm @ +/-70A max: 10 ohm 60 ohm with +/-15V @ +/-50A max: 50 ohm 155 ohm @ +/-70A max: 50 ohm 90 ohm 4. Secondary normal current: 50mA rms 5. Conversion ratio: 1:1000 6. Supply voltage(+/-5%): +/-12V~+/-15V 7. Current consumption: 10mA+ Secondary output current 8. Isolation test: Between the primary circuit to the secondary circuit(+.-.M):2.5kVrms/50Hz/1min Accuracy - Dynamic performance data: 1. Accuracy @ I_PN, T_A=+25 oC , @+/-12V~+/-15V: +/-0.7% 2. Non-linearity: better than +/-0.2% 3. Offset current: not more than +/-0.2mA(@+25°C) 4. Residual current @ I_P=0, T_A=+25°C), after an overload of 3xI_P: +/-0.3mA 5. Thermal drift: +/-0.5mA(0 °C ~+70 °C) +/-0.6mA(-25°C ~+85°C) 6. Reaction time @10% of I_P max : less than 500ns 7.
