Solid Core Current Sensor – UCT-0750 by Magnelab

30-100 Aac input : 333 mVac output. 0.3″ opening

Product Description

Magnelab’s UCT-0750 is a solid core current sensor that transforms an AC input current up to 100 Amps to a 0.333 Volt output.

The UCT-0750 is a compact and reliable solid core current sensor with a 3/4″ opening. It is ideal for new installations because of its durability and high accuracy.

Frequent Applications

  • Data logging
  • Recording
  • Power monitoring
  • Energy management
  • Cost allocation

The UCT-0750, like other current sensors, is used to determine the current (measured in Amps) passing through a conductor (wire, bus bar, etc). This is needed, along with the voltage, to determine the amount of power being used (measured in kW). Click here for more information on monitoring.

As with most of Magnelab’s other current sensors, the UCT-0750 is 0.5% accurate when operating from 10% to 130% of the rated input current.  For example, given a 120A circuit breaker, the UCT-0750-100 would work well, because it will maintain its accuracy up to 130A (130% of the rated input).

Compatible power meters accept a voltage input.  Look for meters on our website that start with this symbol:
