Let's get familiar with our RIB current transformers! These CTs are compact in size and have a split-core, solid-core, or Rogowski coil construction, making them easy to install in a power metering application. Notable precision boasts a typical accuracy of 0.5%, which makes them perfect for revenue-grade jobs. These units output a 333mV analog signal from the 6 feet worth of output wire. Consult the factory for alternative analog output options. Most of all, these current transformers are designed and made in the USA with global materials. At Functional Devices, product quality is of the utmost concern, and these CTs deliver just that.
