MFM with high accuracy, configurability and easy integration

Elite 440 is a multi-line, three-phase digital panel meter for accurate and reliable measurement of electrical parameters (voltage, current, power, frequency, etc.). It is used for both industrial and commercial applications and features a large multi-line backlit LCD display that displays four parameters simultaneously. Modbus communication capability allows easy integration with energy monitoring systems. Expansion modules can be fitted for enhanced system integration (pulse inputs / outputs or analogue outputs and ethernet).

Application

  • Commercial and industrial sub-metering and energy management system (EMS) applications
  • Building management and monitoring systems (BMS)
  • High, medium and low-voltage switchgear panels
  • Control and relay panels
  • Power Control Centre (PCC) panels
  • Motor Control Centre (MCC) panels
  • Relaying and control outputs
  • Plant automation and monitoring system (SCADA / DAS)

Benefits

  • Easy interface with external devices through built-in Modbus (RS-485 / Ethernet)
  • Detachable connectors for easy installation
  • Diagnostics assistance on display
  • Suitable for star or delta connections and low or high-voltage applications
  • Cost-effective online monitoring
  • Field-configurable CT / PT primary and secondary values using push buttons

Features

  • Large four-line seven-digit display (9.7 H x 5 W mm) with quadrant identification section and bar graph for instantaneous power-level indication
  • High accuracy: Class 0.2s, 0.5s, 1.0
  • Average THD measurement for voltage, current and power, up to 31st harmonic
  • Measurement selection (star or delta / 3P 4W or 3P 3W)
  • Modbus communication via RS-485 port / ethernet
  • True root-mean squared (RMS) metering
  • Calibration LED for accuracy test on site
  • Wide and configurable current range (1-2A and 5-10A)
  • Wide-range of auxiliary power supply, suitable for high-voltage or low-voltage installations
  • Maximum demand recording
  • Midnight snapshot (values) for selected energy registers
