Three-phase Static Multi-function Meter
DTSD546 three-phase multifunction meter adopts the technology of digital signal operation, digital filtering, digital error correction, and digital calibration without and physical adjustment component. It is a highly stable meter with immunity to tem perature i nfluence. Besides measuring the data such as voltage, current and power factor accurately, the meter also has strong communication functions, and is widely used in industrial power system.
