Curren t Sensors RS-A and RSS-A Model Open Loop Hall Effect Description The RS/RSS-A Series is a current sensor that accurately measures AC and DC currents and provides electrical isolation between the circuit being measured and the output of the sensor. One package provides nominal current measurements from 100 to 1000 amps and has the versatility to be panel or bulkhead mounted. Features Applications • High accuracy • Motor controllers and drives • Wide frequency range • Battery supplied equipment • Excellent linearity • Switch mode and uninterruptable power supplies • Safety isolation • Welding equipment • Heavy duty industrial housing • Panel or bulkhead mounting • Single or dual supply voltage option Specifications Electrical Data Nominal Range Measurement Range Output (mV/A) RS RSS RS/RSS - 1000-A................................. 1000 Amps ±1000 Amps 4.00 1.60 RS/RSS - 600-A ................................... 600 Amps ±1000 Amps 6.67 2.67 RS/RSS - 500-A ................................... 500 Amps ±1000 Amps 8.00 3.20 RS/RSS - 400-A 400 Amps ±1000 Amps 10.00 4.00 ...................................
