Functions and features
COMTRADE and PQDIF
- Quick analysis due to a standardized file format
- Data exchange directly from the device via SFTP and web server
Events and transients
- Detect transients and events with real-time monitoring
- Quick reaction times due to flexible settings for threshold values
- 18 μs detection of transients
Power quality
- Avoid downtime and interruptions whilst improving operating efficiency
- Identify potential faults and protect systems from damage due to early detection of discrepancies in the measurement circuit
- Record flickers and harmonics up to the 63rd harmonics current
- Capture waveforms for root cause and event analysis
Comparator
- 125 comparators in 32 comparison groups
- Early warning if threshold values are exceeded and if discrepancies arise in consumption
- Avoid expensive downtime via overcurrent alarms and collective fault signals
- Reliable data transmission via OPC UA or modbus
Modbus Whitelisting
- Improve operational safety via the modbus protocol with intelligent firewall
- Secure data traffic and effectively isolate threats
Modbus
- Gateway for seamless integration of other devices from downstream measurement levels
- Extensive scope for communications with the combination of RS485 remote communication and high-speed Ethernet
- Fast initial commissioning due to fixed patterns on Modbus address lists
- Customized address lists Shift each value in accordance with specific requirements and create individual modbus addresses
Ethernet
- Dual Ethernet with switched mode and daisy chain function
- Maximize network capacity and safely connect other devices in series
- Double the network security and flexibility: Integration into two networks for safe and efficient data management
- Dedicated bandwidth for optimal power during critical processes
USB connection
- Convenient and safe fault analysis directly on site via a connectable external display
- Quick commissioning Quickly and easily upload device configurations and updates via USB
Measuring groups
- With virtual meters - create and combine measured variables and measurement groups – totally without additional hardware
- Use virtual parameters and reduce hardware costs considerably (savings of up to 25% per measurement channel)
- Monitor and analyze energy consumption and power over several modules – even for 3- and 4-phase applications
Webserver
