Schneider Electric Releases Disturbance Detection And Waveform Capture In Compact Power Meter
Palatine, IL - Schneider Electric's North American Operating Division introduced under its Square D brand of power management products the PowerLogic PM870 power meter, the newest addition to the Series 800 PowerLogic power meter family. Designed for electrical installations with power-sensitive processes, the PM870 combines accurate energy and power measurement with power-quality capabilities not typically found in a compact power meter.
In commercial buildings and industrial facilities, the PM870 power meter can help facility managers establish and maintain LEED certification through measurement, verification and reduction of energy consumption. The new power meter also can help to extend equipment life by evaluating equipment usage patterns, and improve system reliability by minimizing downtime through accurate detection and diagnosis of power quality disturbances.
The PM870 meter provides disturbance detection and configurable waveform capture, used to detect, capture, and troubleshoot current and voltage sags and swells that can disrupt sensitive processes. With zero blind-time metering, the PM870 simultaneously monitors all three phases of voltage and current with extreme accuracy even for fast-varying loads, such as those found in welding applications.
Accurate demand and energy measurements in the PM870 (meeting both IEC 62053-22 and ANSI C12.20 Class 0.5S standards) help facility managers track costs, allocate energy expenses, and sub-bill by department, area or individual process. The meter's on-board logging memory prevents gaps in critical billing or troubleshooting data due to network outages or computer server downtime.
The PM870 meter's compact size (96 x 96 mm) and mounting depth of 70 mm make it suitable for installation in low voltage switchboards (even in shallow cable compartments), stand alone machines, and a wide range of commercial and industrial applications.
The PM870 meter mounts with only two clips; no tools are required. In addition, the PM870 meter does not require potential transformers (PTs) in systems up to 600 volts line to line. Field-installable input/output modules can be added at any time as the user's needs require the monitoring of status points, and the energy monitoring of water, air, gas, electric, steam (WAGES) pulses or other new functions.
The large, easy-to-read, backlit display shows multiple metered values at a glance. The display is also available with flexible remote mounting capabilities that allow the meter base unit to be installed inside with the display mounted on the low voltage cabinet. This feature is ideal for installations when local regulations do not permit over 120V on panel doors.
Standard RS485 Modbus communications allow the PM870 meter to be used as part of a PowerLogic power and energy management system, in which captured waveforms, alarms, billing data and more can be uploaded to software for viewing and analysis.
