AEMC AC Current Probe Model MN313 The MN313 is a high accuracy and lower phase shift AC current probe. It has a 1000:1 ratio and an output of 1mA per amp in the primary (inside the jaws). The MN313 has an integral 5 ft (1.5m) lead terminated by shrouded banana plugs. The MN313 has a protective diode across the output that limits the voltage in the case of an open secondary. Maximum Conductor Size 0.78" (20mm), bus bar 20x5mm Current Range 150Arms AC Measurement Range 0.1 to 200A Output 5 ft (1.5m) lead with 4mm safety banana plug Transformation Ratio N/A Output Signal 1mA/AAC (100mA @ 100A) Accuracy 50/60Hz 1% @ 80A Frequency Range 40Hz to 10KHz Phase Shift at 50Hz 2° @ 80A Open Secondary Voltage N/A Load Impedance 1é Overload 200A continuous Dimensions (H x W x D) 5.47 x 2.00 x 1.18 (139 x 51 x 30mm) Weight 6.3 oz (180g) Operating Temperature 14° to +131°F (-10° to +55°C) Storage Temperature -40° to +158°F (-40° to +70°C) Operating Humidity 90% RH Pollution Degree 2 Ingress Protection (Ip) IP40 EMC EN 61326-1 Safety Compliance EN/IEC 61010-1 600V CAT III,EN/IEC 61010-032
