AC DC Digital Isolation Current Transducer

This series of AC current transducers provides precise and reliable measurement for both single-phase and three-phase AC circuits. The devices convert AC current signals into standard DC analog signals or digital outputs. With options for split-core and solid-core structures, they support applications requiring continuous current monitoring, protection, and control. Models with True RMS measurement and MODBUS communication are also available for complex industrial systems.
