INTEGRATED DISCONNECT/RECONNECT SWITCH

• Integrated 100A switch can be locally or remotely controlled.

• Supports customer move-in/move-out management, load limiting, and pre-paid metering.

LOAD PROFILE

• Up to 16 channels of remotely configurable load profile data can be captured at programmable intervals ranging from 5 minutes to once a day.

• Load profile storage capacity is a function of the number of channels and the log interval. For example, single-channel, 1-hour data can be retained for 180 days.

ADVANCED POWER LINE COMMUNICATION

• Every NES smart meter includes Echelon’s proven, standards-based, power line communications technology — the world’s most widely deployed signaling technology.

• Every meter includes an automatic repeating function.

• Communicates with an NES Data Concentrator.

POWER QUALITY ANALYSIS

• Long and short outage detection with configurable time threshold.

• Voltage sag and swell detection with configurable voltage and duration thresholds.

• THD event detection with analysis up to 10th harmonic to reveal unusual conditions.

TIME-OF-USE METERING

• Remotely configurable time-of-use metering leading to peak load reduction supports 4 tariff tiers with up to 10 tier switches per day.

• Rich calendar functionality with day schedules for each season, adjustable time zones, and support for daylight savings time.

• Support for changing the calendar through a pending time-of-use calendar.

DEMAND METERING

• Optional demand metering allows billing based on maximum demand.

• Includes support for block or rolling demand calculations, configurable demand intervals, and logging 2 coincident parameters.

• Supports local or remote demand reset.

PREPAY METERING

• Energy credit-based prepay functionality including varying deductions per time-of-use scheduling, configurable emergency credit, and audible low credit alarm.

TAMPER DETECTION

• Cover tamper is detected, logged, and communicated. Cover tamper operates even during a power failure.

• Measurement technology is immune to magnetic tampering. However, magnetic tamper can be optionally detected.

• When used together, alarms, measurements, and tamper events can detect most fraud and tamper attempts.

MULTIPURPOSE EXPANSION PORT (MEP)

• Optional MEP lets partners attach secure hardware extensions to the meter for communication with devices like in-home displays, or gas and water meters.

• Powered MEP option can provide up to 1 Watt of power to external devices.

• Lets utilities expand meter capabilities when needed.

MICRO-GENERATION SUPPORT

• Measures forward, reverse, and net active energy.

• Measures kvarh import and export.

• Measures 4-quadrant kvarh when demand metering is included.

OTHER STANDARD FEATURES

• MID Class B active power, Class 2 reactive power.

• -40°C to +70°C operating temperature range.

• Event log with circular buffer to store 100 events.

• Large-character, auto-scrolling, eight-digit LCD display.

• Two pulse output LEDs to represent active and reactive energy.

• Optical port for use with NES Provisioning Tool.
