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.

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.

Communications
Model PM710 and PM750 meters offer a standard RS-485
communication port that allows data to be uploaded to software for
viewing and analysis. 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.

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.
