Field upgradeable functionality for future requirements with communications and I/O cards as well as software option functionality upgrades and logging memory (up to 128MB) to log years of captured data
Flexible installation mounting with standard ANSI cutout as well as available optional meter enclosures for retrofit applications and no display transducer version (EPM 7000T) for DIN rail mounting

Applications

New or retrofit (available enclosures) revenue energy billing or reconciliation (demand, time of use) for utility or industrial applications
Power quality studies/alarming/event capture for utility or industrial event investigation/reconciliation, ensuring uptime and predictive maintenance for critical power quality sensitive assets (Utility substation, Data Centers, Manufacturing, Hospitals)
Energy metering or power quality monitoring for harsh environments with standard conformal coating.

Enhanced Revenue and Power Quality Metering

The EPM 7000P has been designed with features to satisfy both revenue and power quality metering for utility substation and industrial applications.

Accurate Revenue Energy Metering

The EPM 7000P provides several features to support accurate Revenue Energy metering including: an Energy Test Pulse; ANSI C12.20 0.1% and IEC 62053-22 CL 0.2S Accuracy Class certification; Time of Use; CT/PT Compensation.

This allows the EPM 7000P the flexibility and capability to be installed either as a utility or industrial device to ensure accurate readings and assist with reconciliation of energy consumption.

Multifunction Metering & Power Quality Monitoring

The EPM 7000P can provide a total picture usage and power quality as different points within a power distribution network on critical infrastructure such as data centers, allowing users to make power related decisions quickly and effectively.

Extensive Logging Capability

The EPM 7000P provides up to 128MB of memory for logging.

Extensive Communications and I/O Cards

The EPM 7000P provides two universal option slots for communications and/or I/O. The unit can be easily configured to accept new I/O cards even after installation by auto-detecting installed I/O option cards. Up to 2 cards of can be used for communications and or I/O per meter providing a range of integration possibilities.

Along with I/O expandability the EPM 7000P can integrate with many different systems, using multiple standardized protocols such as Modbus RTU/ASCII/TCP, Level 2 DNP3 and IEC 61850. Expandable communications cards allows customization for system requirements at time of purchase as well as in the future if requirements change.

Comprehensive, Upgradeable Features

Along with basic standard features (Software Option A) the EPM 7000P provides field upgradeable, post installation Software Options. An unlock key for the higher Software Option can be entered in the GE Communicator Setup software providing more functionality with the same installed unit in the future. The following table illustrates the available features and upgrades.

EPM 7000PT Transducer Option

The EPM 7000P is available in a Transducer Option (EPM 7000PT). The EPM 7000PT is ideal for use in applications where a meter display or front port is not required and/or there are mounting/installation constraints in terms size or location within a switchgear cabinet or enclosure. The EPM 7000PT Transducer option also provides a more economical alternative to the EPM 7000P when a display is not required and there are only communications requirements.
