Simple installation and cost effective PowerLogic® PM700 series power and energy meters Buildings Retail Industry Compact, cost-effective power and energy meters PowerLogic® PM700 series power and energy meters offer outstanding quality, versatility and functionality in a cost-effective, ultra-compact unit. OEMs, panel builders and customers in industrial, buildings or infrastructure environments will find the meters ideal for replacing analog meters or for adding metering to custom panels, switchboards, switchgear, gensets, motor control centers and UPS systems. The meters are simple to use and offer large, bright LCD displays. They can be used for stand-alone metering or seamlessly integrated with PowerLogic® power and energy management systems. The meters are available in four models with incremental features. All models offer power, demand, energy, power factor, frequency and THD measurements, with higher models offering a choice of digital inputs, outputs, RS-485 communications and alarm functions. Perfect for monitoring right down to the tool level, the meters’ IEC Class 1 or Class 0.5 certified accuracy make them suited for many applications. Typical applications >>Energy savings • Measure efficiency, reveal opportunities and verify savings • Sub-bill tenants for energy costs • Allocate energy costs to departments or processes • Reduce peak demand surcharges • Reduce power factor penalties • Leverage existing infrastructure capacity and avoid over-building >>Energy availability and reliability • Verify the reliable operation of equipment • Improve response to power quality-related problems Installation Mounting Options The meters come with an integrated display and can be quickly panel mounted through a square cutout using two clips with no tools required. A small panel footprint and shallow 50 mm (1.97 in.) depth behind the mounting surface maximises free space for other electrical devices inside a switchgear cabinet when mounted on the door. This makes the meters suitable for low voltage switchboards, shallow cable compartments or on standalone machines. (A) 96 mm (3.78 in.) 50.0 mm (1.97 in.) Circuit and control power connections All models are compatible with low and high voltage 4-wire wye and 3-wire delta systems and are suitable for three-phase (3P, 3P + N), two-phase and single-phase systems. Direct connect inputs up to 480 V ac line-to-line or use voltage (potential) transformers for higher voltage systems. All models offer a universal AC or DC power supply.

The port offers 2-wire connection, operates at speeds up to 19.2 kbaud, and supports Modbus® RTU protocol. Software integration Model PM710 and PM750 meters are compatible with PowerLogic® facility-level or enterprise-wide power and energy management systems. Real-time and min/max data can be automatically retrieved for analysis at the system level. Compatible with PowerLogic® ION Enterprise®, PowerLogic® System Manager® , PowerLogic® PowerView™ and PowerLogic® Tenant Metering software. Modbus compatibility supports integration with building automation, SCADA and other third-party systems. A. Meter dimensions, showing depth behind panel, and display bezel side and front dimensions.

Power and energy measurements Metering is performed by zero-blind sampling all inputs at 32 samples/cycle with a data update rate of 1 second. The meter offers a range of instantaneous RMS, power, demand and energy measurements suitable for real-time monitoring, energy management and sub-billing purposes.

Power quality analysis All models offer total harmonic distortion measurement (THD) on voltage and current, per phase and min/max. The model PM750 can alarm on THD levels. Power factor display* * Available for model PM750 only. Front panel display The anti-glare backlit green LCD is easily read in extreme lighting conditions or viewing angles. An intuitive navigation with self-guided menus make the meter easy to use. The large 6-line display offers summary screens that simultaneously present up to 4 concurrent values, including power and energy values, I/O conditions or alarm status. Bar chart displays graphically represent system loading and I/O conditions. Historical and active alarms include timestamps. Digital inputs and outputs The model PM700P has two solid-state KY outputs dedicated to kWh and kvarh pulsing. The model PM750 has one digital output three operating modes: external control (default), alarm (control relay in response to alarm condition) and kWh pulse. The PM750 also has two digital inputs featuring two operating modes: normal and demand synchronisation. Use these to trigger alarms or monitor equipment status. Alarm and control functions The PM750 features 15 user-configurable alarms that can be used to trigger on over and under conditions most commonly found in power systems. Get early warning of impending problems that could lead to equipment problems or downtime. Communicate alarms through the RS-485 port for remote monitoring and use the meter’s digital outputs for control applications to help avoid penalties and perform proactive maintenance.
