Honeywell 50A Closed Loop Current Sensor CSNE151-204 Preliminary Specification 2000 Turn 50Arms Current Sensor 1. DEFINITION. The CSNE151-204 is a current transducer based on the principle of magnetic compensation. It provides electronic measurement of DC, AC.pulsed currents,.their combinations, with galvanic isolation between the primary (high current).secondary circuits. 2. ELECTRICAL DATA. Nominal current (In) : 50 A.t rms Measuring range (Continuous) : 0 to ± 50 A.t Measuring range (AC Peak) : 0 to ± 90 A.t[3] Measuring resistance (at +70°C) : Rm min Rm max with ±15V at ± 50 A.t max : 0 ohm 250 ohm [1] at± 90 A.t max[3] : 0 ohm 54 ohm[1] Nominal analogue output current at 50A : 25 mA Turns ratio :1,2,3,4 /2000 Accuracy at +25°C :maximum ±0.5% at In Supply voltage :±15V dc (±5%) Galvanic isolation : 5 kV rms / 50 Hz / 1 minute 3. ACCURACY - DYNAMIC PERFORMANCE. Zero offset current at +25°C : better than ±0.3 mA Thermal drift of offset current 0°C to 70°C : better than ±0.6 mA Linearity : better than ±0.3 % Response time :better than 1μs Bandwidth :DC to100 kHz dI/dt : better than 50A/μs 4. GENERAL DATA. Operating temperature : -40°C to +75°C Storage temperature : -40°C to +90°C Current consumption : 10 mA plus output current Secondary internal resistance (at +70°C) : 190 ohm Sensor housing :Insulated plasticcase Connection (Primary) : 4 x 1.25mm busbars Connection (Secondary) : 3 x 1.0mm pcb pins Notes. 1.
