Transparent power quality and energy consumption monitoring

  • Transparent power quality and energy consumption monitoring
  • Transparent power quality and energy consumption monitoring
  • Transparent power quality and energy consumption monitoring

The CENTRAX CU5000 combines the functionality of a highly accurate instrument for heavy current applications with the possibilities of a freely programmable Soft-PLC in one housing. The connection of the process environment may be performed by communication interfaces, via digital I/Os, analog outputs or relays.

  • Technical characteristics

    PLC functionality

    • Based on Codesys, 3 performance classes
    • BASIC: Flexible processing of the data of the measurement device using the complete I/O functionality
    • ADVANCED: BASIC + Modbus RTU/TCP master and time-dependent processes
    • PROFESSIONAL: ADVANCED + self-defined websites and local visualizations + Codesys data logger

    Condition monitoring

    • Provision of all voltages, currents, powers, power factors every 10/12 cycles
    • Variance of system variables with time reference
    • Measurements of Modbus slaves

    Energy flow analysis

    • Power mean-values with trend-analysis for preventing load-peaks
    • Load profile storage with fluctuation range (min/max) per interval
    • Active energy class 0.2S, Reactive energy class 0.5S (HT/LT, demand/delivery), configurable resolution
    • Further mean-values and meters with selectable base quantity

    Power quality analysis

    • Harmonic analysis acc. IEC 61000-4-7
    • Assessment of voltage and current imbalance
    • Phasor and phase sequence display for connection check
    • Waveform display
    • Optional disturbance recorder for PQ events (voltage dip, swell, interruption) acc. IEC 61000-4-30 Ed.3 with RMS1/2 and waveform recordings

    Hardware options

    Up to 2 modular extensions: Analog outputs ±20mA (2/4), relay outputs (2), digital inputs (4) active / passive, GPS time synchronization, fault-current monitoring (residual or earth current), temperature monitoring (Pt100, PTC), IEC61850

    Communication

    • Ethernet (Modbus/TCP, http/https, NTP, SFTP, SYSLOG)
    • Modbus/RTU master or slave
    • Optional: IEC61850
    • Scheduled data export to SFTP server

    Security

    • Flexible Role Based Access Control
    • Encrypted communication via HTTPS
    • Audit Log records all security related procedures, support for SYSLOG for transfer to central network monitoring server
    • Client whitelist: IP address list for restricting authorized computers
    • Digital firmware signature: Prevents that manipulated firmware gets into the device via update

    Further features

    • 4 current and 4 voltage channels with 0.1% accuracy, direct measurement or via transformers
    • Measurement category 600V, CAT III (voltage), 300V,CAT III (current)
    • Standard IOs: 1 digital input, 2 digital outputs
    • Optional UPS (5x3 minutes)
    • Data logger with16 GB data memory (option)
    • Sampling rate: 18kHz
    • Monitoring and alarming via limit values and monitoring functions
    • Device for hat-rail mounting 160x110x70mm
    • Identical operation as devices of the AM/PQ/DM series
