3P3W Three Phase Multi-function Meter (CT/VT)

Overview

ST34G05 adopts ultra-large-scale digital signal processing chip, fully isolated standard RJ45 communication interface and infrared communication, configurable carrier communication module and wireless communication module. Advanced technologies such as large-screen wide-temperature liquid crystal display and AES128 security encryption algorithm. The manufacturing uses advanced SMT surface mount technology and imported high-performance long-life electronic components. The shell is made of high-strength, flame-retardant and environmentally friendly materials, novel and practical, with high dielectric strength and corrosion resistance. Ideal for smart grid structuration.
