EM-M69 CURRENT MEASURE UNIT 50A dc/ac FEATURES: • Wide frequency range • True RMS measurement • Also for thyristor power controller and inverter current measurement • Dip switch settable • 50A RMS (150A peak) • mA and V output • Gain and zero adjustment • Over voltage protected • Reversed polarity protected • Easy to connect • Rail mounting base available EM-M69 uses zero compensated Hall transducer current sensor, that works in a wide frequency range, from dc to 10 kHz. This feature gives true current value also in inverter and thyristor power controller applications. The device output signal is either momentary (direct) or converted to true RMS value. Output signal can be set to mA or V. The device is scaled 0-100% => 0-50A, the scale can be fine tuned with zero and gain adjustments. The scale can also be set by adding wiring through loop, for example two wires double the output 0-100% => 0-25A and so on. The device is connected like a three wire transducer: supply, signal, gnd. The input is protected against faulty connections and voltage peaks. WIRE HOLE 13x10mm TECHNICAL DATA: Operating voltage Current comsumption Measuring range Output signal (mom.)
