EPM 7100 Power Quality Meter - Energy and Demand Submeter with Data Logging and WiFi


The EPM 6100 is a powerful tool that allows customers to monitor and manage their energy usage within factories, businesses and across campuses. The EPM 6100 is a multifunction meter that features ANSI C12.20 (0.2% class) accuracy and RS485, RJ45 Ethernet or IEEE 802.11 WiFi communication connections, making the meter easy to deploy in modern and older communications systems. Early detection of power problems is facilitated through THD and the alarming capabilities of the EPM 6100. The units use standard 5 or 1 amp CTs (either split or donut), surface mount to any wall and are easily programmed in minutes.

Direct interface with most building management systems reduces integration costs

Easy installation reduces set-up time and cost

Meets ANSI C12.20 (0.2%) and IEC 687 (0.2%) classes


Applications

Allocate energy usage throughout multi-tenant settings, such as industrial and university campuses, office towers, apartment complexes and shopping malls

Detect power problems early in government, military and airport facilities

Energy monitoring to increase OEMs efficiency


  Monitoring and Metering    
  Traceable Watt-Hour Test Pulse for Accuracy Certification
To be certified for revenue metering, power providers and utility companies need to know that the billing energy meter will perform to its stated accuracy. To verify the meter's performance and calibration, power providers use field test standards to ensure that the unit's energy measurements are correct. Since the EPM 6100 submeters are traceable revenue meters, they contain a utility grade test pulse allowing power providers to verify and confirm that the meters are performing to their rated accuracy. This is an essential feature required in all billing grade meters.

Utility Peak Demand Metering
EPM 6100 submeters provide user-configured Block Window or Rolling Window Demand. This allows customers to set up a particular utility demand profile. Block Window Demand is demand used over a fixed user-configured demand period (usually 5, 15 or 30 minutes). Rolling Window Demand is a fixed window demand that moves for a user specified sub-interval period. An example is a 15 minute demand using 3 subintervals, providing a new demand reading every 5 minutes based on the last 15 minutes. Readings for kW, kVAR, kVA and PF are calculated using utility demand structures. Other parameters offer max and min capability over the user-selectable averaging period. Voltage provides a non-rolling instantaneous max and min reading, displaying the highest surge and lowest sag seen by the meter.
 

 
  Communications    
  Standard Modbus RS485 Communication
Standard communication includes an RS485 output speaking Modbus protocol. This allows the unit to be connected to any serial RS485 bus using the Modbus interface. The unit communicates easily with most building automation or other software systems. Baud rates are up to 57.6K baud to provide fast update times.

WiFi or LAN-Based Ethernet
The unit offers two Ethernet options — either an RJ45 or WiFi connection. The WiFi option allows the EPM 6100 submeter to be used on standard WiFi base stations.

IrDA Port
Use an IrDA-equipped laptop PC to program and read the EPM 6100 submeter.

KYZ Pulse
For applications in which a pulse is needed, the unit also provides a KYZ output which pulses proportional to the amount of energy consumed. This feature is used for pulse counting applications or for building management systems where serial or Ethernet protocol is not available.
