CVM-A1500 Power Quality Analyzer
CVM-A1500 is a panel-mounted power quality analyzer designed for critical electrical installations where continuous energy monitoring, waveform capture, event recording and power quality visibility are required.
It includes an integrated Energy Management Software environment and an internal HTML5 web server, allowing users to monitor the installation locally or remotely using a standard web browser.
Overview: Advanced Power Quality and Energy Monitoring
CVM-A1500 is designed to be installed at the most relevant or critical point of an electrical installation. It records and monitors a wide range of electrical variables, including RMS, maximum and minimum values, energy data and power quality events.
The analyzer captures swells, dips, interruptions every half cycle and transients according to IEC 61000-4-30 Class A requirements. When an event occurs, the device records the voltage and current waveform so that the disturbance can be reviewed with proper evidence.
Key positioning
CVM-A1500 is suitable for main incomers, critical feeders, production facilities, semiconductor plants, data centres, hospitals, airports and other installations where electrical disturbance visibility is important.
Power Quality Investigation Workflow
CVM-A1500 converts electrical disturbances into usable evidence for engineering analysis, compliance reporting, maintenance action and long-term power quality improvement.
Key Features
Class A Power Quality
Registers swells, dips, interruptions and transients according to IEC 61000-4-30 Class A.
Waveform Capture
Captures voltage and current waveform associated with power quality events and transients.
Harmonics up to 63rd
Measures voltage and current harmonic decomposition up to the 63rd harmonic.
Integrated Web Server
HTML5 web server allows installation control using a standard browser without dedicated local software.
Energy Management Software
Integrated EMS supports historical data registration, analysis and energy management review.
Expandable I/O
Expandable up to 3 modules for additional inputs, outputs and communication interfaces.
Power Quality Visibility
CVM-A1500 measures key power quality variables defined in EN 50160, including flicker, unbalance coefficient, asymmetry coefficient and harmonic decomposition. It also provides oscilloscope-style real-time waveform viewing for voltage and current.
