MN312 is a high accuracy and lower phase shift AC current probe. It has a 1000:1 ratio and an output of 1mA per A in the primary (inside the jaws). The MN312 has a jack output that accepts 4mm banana plugs. The MN312 has a protective diode across the output that limits the voltage in the case of an open secondary.
