The AEMC SD661 is a 1000 Amp AC Current Probe. Excellent transformation and low phase shift, plus a broad frequency response, permit accurate measurements of current. The high quality magnetic cores and uniform windings provide high sensitivity for very low level current measurements, as well as enough magnetic power for accurate measurements up to 1000 A AC. The unit has proportional mV output for direct readings on oscilloscopes. Three-position slide switch on the handle selects ranges. Specifications. Current Range: 100 m V / A; 100 mA to 20 A peak, 10 mV / A; 0.5 to 200 A peak, 1 m V / A; 5 to 2000 A peak. Output Signal: mV output (2000 mV peak max). AC Current Accuracy: 100 mV / A (100 mA to 20 A peak); 3% of reading ± 10 mV, 10 mV / A (0.5 to 200 A peak); 2% of reading, 1 mV / A (5 to 2000 A peak); 2% of reading. Overload: 1200 Arms for 30 mn. Frequency Range: 5 Hz to 50 kHz (-3 dB with current derating). di/dt Max: 10 A/S. Rise or Fall Time: <40 µs. Working Voltage: 600 Vrms max. Influence of Adjacent Conductor: < 0.2 mA/AAC.
