CHAPTER 1—INTRODUCTION
WHAT IS THE POWER METER?
The POWERLOGICPower Meter is a compact, low-cost power meter for
basic industrial power monitoring applications. The power meter has been
designed for ease of installation in industrial retrofit applications. Power
meter applications include new equipment such as switchboards,
panelboards, and Low Voltage Drawout (LVDO) feeders, and it can be used
in POWERLINK installations for metering the main. Additionally, the power
meter can be used for Motor Control Centers (MCCs) and busway.
The power meter can be purchased with an optional display for local display
and setup. Also, the display can be purchased separately to be used as a
power meter programmer. The display fits standard 4-1/4" (108 mm)
ammeter and voltmeter cutouts. It connects to the power meter by a cable
that supplies both communications and power.
All power meter modules can be mounted up to 50 feet (15.2 m) from the
display. You can mount them on an enclosure floor or wall, on a horizontal
35 mm DIN rail, or directly behind the display on the panel door.
The power meter is completely supported in POWERLOGIC System Manager
Software releases SMS-3000, SMS-1500 and PMX-1500, including setup and
resets. SMS-770/700 v. 2.23 and EXP-550/500 v. 1.23 provide limited support,
including real-time and historical data monitoring and PC-based alarming
and trending.
Some of the power meter’s features include:
• ANSI C12.16 Revenue Accuracy
• True RMS Metering (31st Harmonic)
• Accepts Standard CT and PT Inputs
• Direct Connect up to 600 V
• Fits Standard 1% Ammeter/Voltmeter Mounting Holes
• Optional Display to View Meter Values
• Power Quality Readings—THD (Voltage and Current)
• On-board Clock/Calendar
• Easy Setup through Remote Display (Password Protected)
• RS-485 Communications Standard
• System Connections
– 3-Phase, 3-Wire Delta (Metered or Calculated B Phase)
– 3-Phase, 4-Wire Wye
• Operating Temperature Range (0°C to +60°C)
