A series of intelligent self-tuning PID regulator is using the new artificial intelligence computer control instrumentation reasoning and decision-making, is widely used in industrial equipment and production processes of various types of industrial temperature, pressure, flow, level, speed, speed, density, humidity, etc. Display and control parameters. The intelligent control instruments company brings together many years of industry experience in manufacturing theory and instrument control, the variety of practical functions integrated in one product among control instrumentation principle, the classical control theory and artificial intelligence combine to make this instrument can achieve the desired control effect parameters control instruments, fully demonstrate its unique versatility and practicality. Smart single-phase active / reactive power meter code display power factor control instrumentation sales, the bottom two LEDs denote voltage leads or lags. Overall dimensions (96 × 48) (48 × 96) due to the housing meter size restrictions, only communication interface; no transmission output; no alarm output. ● Selection example: (1) WP-LEPF-C200NT (380V / 380V, 100A / 5A) AC power factor indicator; single-screen digital display; dimensions 80 × 160; no communication interface, no transmission output, no alarm output; the input voltage 0 ~ 380V; Input Current 0 ~ 5A; display power factor 0.200 to 1.000.
