MAMAC Systems CU-870 Analog Current Transducer 4-20mA 10/20/50A Solid Core

The MAMAC Systems CU-870 Analog Current Transducer measures conductor amperage and converts sensed load into a proportional loop signal for control equipment. Magnetic-field variation around an energized conductor produces an internal sensing response, which becomes an analog output representing measured current. This solid-core transducer fits around a passing conductor, with 4-20mA output and 10/20/50A selectable ranges matching monitoring requirements in HVAC systems. Its isolated signal reaches supervisory circuitry, allowing measured amperage to inform regulation and monitored path remains electrically separate from measurement circuitry during normal electrical monitoring within control assemblies without interruption.
