Instrumentation Summary                            Basic Metering Solution and More
s   Real-Time Readings                             The PowerLogic Power Meter is designed for use in basic power metering
s   Current (per phase, N, G, 3-phase)             applications. It can replace conventional metering devices such as ammeters,
s   Current (neutral, N)                           voltmeters, and watt-hour meters while providing powerful capabilities not offered
s   Voltage (L-L, L-N)                             by analog metering. The Power Meter’s true rms readings (31st harmonic
s   Real Power (per phase, 3-phase)                response) accurately reflect non-linear circuit loading more than conventional
s   Reactive Power (per phase, 3-phase)            analogue metering devices. The Power Meter calculates the neutral current, which
s   Apparent Power (per phase, 3-phase)            can assist in identifying overloaded neutrals due to either unbalanced single
s   Power Factor (per phase, 3-phase)              phase loads or triplen harmonics. Circuits can be closely monitored for available
s   Frequency                                      capacity by keeping track of the peak average demand current. Accurate circuit
                                                   loading information is essential to get the most out of existing power equipment
s  Demand Readings                                 while maintaining power system reliability.
s  Demand Current (per-phase present, peak)        The Power Meter provides a full complement of accurate true rms metering
s  Average Power Factor (3-phase total)            values through its display, or via the standard RS-485 communication port to
s  Demand Real Power (3-phase total)               a PowerLogic Power Monitoring and Control System. Refer to the tables for
s  Demand Reactive Power (3-phase total)           information about the metering values reported by each model. A relay output is

s   Energy Readings                                The Power Meter’s small size and variety of mounting configurations allow it to be
s   Accumulated Energy, Real                       readily installed in new equipment or retrofit into existing equipment. The Power
s   Accumulated Energy, Reactive                   Meter module can be mounted onto a 35mm DIN rail, or it can be mounted on
s   Accumulated Energy, Apparent                   any flat surface using its four mounting feet. For added simplicity in retrofit
s   Bi-directional Readings                        installations, the panel mounting hole patterns for both the Power Meter module
                                                   and the Power Meter display match the conventional ammeter/voltmeter spacing
s Other monitoring functions                       so the meter and the display can be mounted back-to-back on opposite sides of
s Energy pulse relay output                        a panel surface. In metering installations of 600 V and below, the Power Meter
s RS-485 PowerLogic and Modbus RTU                 provides additional savings in both cost and mounting space by eliminating the
communications                                     need for PTs and control power transformers.

                                                   and resets menus. Since the Power Meter display can be mounted up to 15 m
                                                   away from the Power Meter module, power metering can now be installed in tight
                                                   equipment spaces without sacrificing convenient and affordable local display.
                                                   The communications port on the Power Meter display is optically isolated from
                                                   the 600 V metering connections.

Power Meter
              Powerful Functionality
              The Power Meter accepts inputs from standard 5 A CTs and has full scale input
              of 10 A. The voltage inputs can be directly connected to 3 phase circuits of 600 V
              and below without the need for PTs or CTs. For higher voltage circuits, the Power
              Meter accepts a full range of PT primary values with control power derived from
              the PTs or from a separate source of ac or dc control power. Setup and resets
              are password protected and are easily done through the Power Meter display
              or via the network using System Manager software. PowerLogic or Modbus RTU
              protocols can be selected. All readings are scaled to their actual values without
              the need for a multipler.


              Advanced Functionality
              In addition to the basic metering functions, the Power Meter increases its value to
              you with advanced functionality features.
              Power Quality Readings - Total Harmonic Distorsion (THD) for current and voltage
              readings indicate potential power quality problems, which unchecked, could
              disrupt critical processes or damage equipment.
              Min/Max readings - Min/max readings provide measurements of extreme meter
              values needed for maintenance purposes. These readings can be viewed and
              reset from the display. Min/max resets are password protected.
              Alarm/Relay Functions - The PM-650 has on-board alarms. Alarm functions
              include over/under conditions for voltage, current, frequency, and phase
              unbalances. In addition, these alarms can be assigned to operate the solid-state
              output.
              Event logging - When an alarm condition occurs, the PM-650 Power Meter logs
              the event in nonvolatile memory. These events can be viewed from the display or
              PowerLogic software.
              Data Logging - As part of a comprehensive power system, the PM-650 expands
              metering capabilities with data logging. Values are stored in nonvolatile memory,
              preserving critical data for the interval between logging updates via
              communications with the system computer. All metered values are available for
              recording at user defined intervals, offering total flexibility. A typical log
              configuration is recording demand readings for kW, kVAR, and kVA, at hourly
              intervals, storing 3 days of information. The meter is pre-configured from the
              factory to log values.


              PowerLogic system Compatibility
              The Power Meter supports standard PowerLogic RS-485 communications up
              to 19,200 Baud with communications links up to 3300 m. A meter can quickly be
              installed into any existing PowerLogic system.
              The Power Meter has been fully integrated into the latest PowerLogic application
              software, System Manager. SMS software enables users to manage their electrical
              distribution systems by providing tabular and graphical data displays, alarms, real
              time and historical time trend tables and graphs, and reports. Power Meter setup
              and reset operations and wiring diagnostics can also be performed from a remote
              personal computer using System Manager software.
              PowerLogic power monitoring devices and systems assist in equipment
              monitoring for cost allocation, troubleshooting, predictive maintenance, planning,
              and more. The lower installed cost of the Power Meter makes it possible for
              facilities to monitor many smaller, less critical feeder circuits enabling whole
              facility power monitoring.
