PowerLogic PM700
power and energy meters
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.

(A) Installation
Mounting Options
96 mm
(3.78 in.) 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
50.0 mm 19 mm 96 mm door. This makes the meters suitable for low voltage switchboards, shallow cable

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.

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.

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

system diagram with multiple real-time metering points.
 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.
