Solid-Core Current Transformer (UCT-1250)

Solid-core current transformer products in the UCT class of sensors from Magnelab are Revenue Grade with better than a 0.50 percent accuracy and a less than 0.26 degree phase angle. Output is controlled by a precision resistor fixed at the industry standard of 0.333 Volt AC. The rugged epoxy encapsulated construction comes with eight feet twisted leads.

Revenue Grade meets or exceeds IEC 618969-2 metering class 0.5. See SPEC sheet for more details.

For a solid-core current sensor with a 5 amp output, see the MGS solid-core current sensor.
