Product Performance

DEIF SCM4.1 is an original DEIF device with strong adaptability, which can be seamlessly integrated into DEIF DM-4 Series control systems, perfectly compatible with PCM4.3 power supply control modules and IOM Series input/output modules, with convenient installation and maintenance. The compact 6TE design saves rack space, and the spring cage pluggable terminals facilitate wiring and later maintenance. The product has high measurement accuracy, reaching Class 0.5 standard, which can accurately collect AC parameters such as three-phase voltage, current, frequency and power, and the measured data is transmitted to the main control module every cycle to ensure data real-time performance. The product has outstanding safety and reliability, with complete power grid protection and fault detection functions. Vector jump detection can quickly identify power grid abnormalities, and the trip relay can quickly cut off the generator in case of electrical faults to avoid equipment damage. The product has strong anti-electromagnetic interference ability, complying with EN 61000 Series standards, with a solid structure, which can operate continuously and stably in harsh industrial environments with wide temperature and dust, providing efficient and reliable support for the measurement, control and protection of industrial power systems.
