The AEMC MN312 is a high-accuracy, low-phase-shift AC current probe designed for precise current measurements. It features a 1000:1 ratio and provides an output of 1mA per ampere in the primary. The probe has a compact design with a large jaw opening that can accommodate conductors up to 250 MCM, making it suitable for use with multimeters, data loggers, recorders, and oscilloscopes. It offers a measurement range from 0.1 to 240A AC, with a frequency response of 40Hz to 10kHz. Equipped with a 4mm banana plug output and a protective diode across the output to limit voltage in case of an open secondary, the probe adheres to EN 61010 safety standards (600V Cat. III) and is UL approved for Canada and the United States. Its double insulation and CE mark ensure safety and quality. Applications include measuring in breaker panels, industrial loads, HVAC/R systems, residential and commercial sites, and monitoring secondary current transformers and data logging systems.
