Model: DM-III Power Quality Recorders， DM-III电能质量记录仪
Amprobe’s full-featured Three-Phase Power Quality Recorders provide the essential functions and capabilities required to operate accuray and effectively in today’s demanding electrical environments.
Application Notes
True RMS （TRMS）
Measures and Records Broad Spectrum of Power Quality Parameters: AC Current, AC Voltage to 600V including Sags and Surges, Harmonics （THD and individual up to 49th）, Active, Reactive and Apparent Power & Energy, Peak Demand, Power Factor, Frequency measurement, Phase sequence
Compatible with wide range of Current Transducers
Comes as a complete kit: CTs, Voltage Leads, Ground Probes & Leads, PC software and download cable are included with this product.
Works with single and three phase systems （Y and Delta）
Detects and records voltage anomalies, Sags and Surges
Built in scope displays waveforms
Phase sequence indication
Records up to 64 parameters （single or three phase） simultaneously
Manual and programmable recording start
Password protection
Selectable fundamental frequency of 50 or 60 Hz
Special data compression system and user selectable rates allow recording from several hours to several years
