Smart modular power analyzer sports rs485, Ethernet, or BACNet communications

By Paul Dvorak | November 12, 2010

The WM40-96 Smart Modular Power Analyzer has an application adaptive display and allows up to 16 freely configurable virtual alarms with OR/AND logic.

A recent energy meter provides a way to measure electrical variables — current, voltage, power, energy, and harmonics. – in applications that demand accurate parameters analysis, control, data stamping, and retransmission. The WM40-96 Smart Modular Power Analyzer comes in a streamlined modular basic unit and plug in modules, so it can be used in almost any application. What’s more, this compact modular power analyzer uses little space in the back side of control doors and switchgears.

The smart power analyzer has an advanced keypad and display that includes five rows of measurements and bar-graph, power-demand indicator. An optional front optical-communication port makes for quick access to measurements and easy programming. Optional hardware expansion modules include serial, Ethernet, and BACNet communication with or without onboard storage for data logging, digital inputs, static, relay and analog outputs. The unit is also capable of temperature and process signal measurements. Tech specs include:

  • Main module plus up to three optional expansion modules
  • Works with single, two, and three phase systems
  • 400/690 VLL or 100/208VLL versions available
  • 90 to 260V ac or dc, or 18 to 60V ac or dc supply options
  • 0.2% current/voltage accuracy
  • Class 0.5 (kWh) according to ANSI C21.1 (revenue grade)
  • Communication protocols: MODBUS-RTU, iFIX SCADA compatibility, MODBUS TCP/IP Ethernet, BACNet-IP over Ethernet
  • System variables: VLL, VLN, AL, AN, VA, W, var, PF, phase sequence, asymmetry
  • Harmonic analysis: THD, TDD K-factor up to 32nd V and I
  • Real time clock and run-hours counter
  • Free setup software
  • Energy measurement: imported/exported, total and partial kWh and kvarh
  • Works with PowerSoft, Carlo Gavazzi Energy Management software
  • Front protection: IP65, NEMA 4X, NEMA12
  • 96 x 96-mm front panel
  • Behind panel depth: 30-mm min, 82-mm max, with 3 expansion modules
  • £ 6 digital inputs, 8 static outputs, 6 relay outputs
  • £ 4 analog outputs (+20mA, +10Vdc)
  • Temperature (Pt) and process (20mA) signal
  • cUL listed and CE marked
