• 【Precision Class 1 Energy Measurement】 With ±1% accuracy for active energy, this meter tracks kWh in single-phase 230V systems, ideal for factories, offices, or retail stores. Direct 5(100)A input suits high-load equipment like motors, while CT input (1.5(6)A) enables flexible large-scale grid monitoring.
• 【Dual Current Input Flexibility】 Switch between direct 100A connection for small setups or CT-based input for high-voltage systems (e.g., apartment complexes or industrial plants). 7-digit LCD displays voltage, current, power factor, and frequency in real time.
• 【Smart RS485 Communication】 Modbus-RTU/DL/T 645 protocol supports remote data logging via PLCs or building management systems. 80ms energy pulse output ensures stable integration with smart grids or renewable energy setups in data centers or warehouses.
• 【Rugged DIN Rail Design】 Mounts on 35mm rails in 63.57290mm space, resisting dust/water splashes (IP54 panel) in workshops. Operates -10℃~55℃ with CE/MID certification, suitable for 24/7 use in manufacturing plants or utility substations.
