AEMC MN313 Current Transformer

Model: MN313

AEMC MN313 AC Current Probe Model MN313 (150A, 1mA/A, Lead)

$174.00 USD

1 to 2 Weeks

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.
