Applications • The PM710/PM750 Power Meters provide accurate and reliable information that make it ideal for: • Energy/demand management • Low voltage panel instrumentation • Cost allocation • Machine monitoring
Energy/Demand Management • The PM710/PM750 Power Meters help to identify potential opportunities to reduce consumer peak demand for electricity. • Some of the actions that the PM750’s could help are: • Energy efficiency and power factor correction improvements • Load shifting from peak to non-peak times • Load Curtailment (interruption to part or full load of the customer) by winding systems or processes down with an appropriate notification • Fuel switching, such as changing from electricity to gas

Accurate energy and power measurement • Full complement of basic metered values including: • Voltage, per phase (L-L, L-N) and 3-phase average • Current, per phase and neutral, and 3-phase average • Energy (kWh, kVARh, kVAh) • Power, per phase and 3-phase total (kW, kVA, kVAR) • Power Demand, present, last, and peak (kWd, kVAd, kVARd) • Current Demand, per phase, present and peak • Frequency and Power factor (signed with PM750) • THD, per phase (voltage and current) Metered values can be viewed on the power meter’s display, or on a remote PC using software.
Accurate energy and power measurement • Minimum and maximum values with date/time stamps • Current and voltage • Power (total) • Power factor (total) • Frequency • THD, per phase (current and voltage) The Power Meter indicates the phase of the Minimum and Maximum reading for Voltage, Current and THD.
Digital Inputs and Outputs • PM750 • 2 digital inputs • Use to monitor breaker status, or other status applications • Demand Interval Synch – will end the power demand interval on the OFF to ON transition. • 1 digital output configurable in one of three modes: • External—Controlled externally, for example by a programmable controller. • Alarm control—Controlled by the power meter in response to an alarm condition. When the alarm is active, the output is ON. • kWh Pulse—The meter generates a fixed-duration pulse output that represents kWh consumption.
Customizable Alarming (PM750) • Fifteen user-configurable alarms • Configurable: Pick up, drop out, and delay • Alarms can be associated to I/O • Trigger alarms in response to a change in input status • Control an output in response to an alarm
Applications • With the addition of an Ethernet Gateway, the meter can communicate via the existing network • Create a simple system using a power meter, EGX400, and a PC with web browser software. View: • Instantaneous readings of amps, voltage, power and energy • I/O status • Alarm status and history • No special software to install • For more advanced applications, consult your PowerLogic Specialist PC with Browser EGX400 Gateway PM7
