E650 S4e Features and Options
The E650 S4e is available with one of three register configurations, AXLS4e, AXS4e or RXS4e, providing the right functionality for all metering applications.
This kilowatt-hour-only version was designed to replace electromechanical meters for energy-only billing applications. The AXLS4e is upgradable to an AXS4e using a software upgrade key.
This meter provides combined demand and time-of- use (TOU), active energy configuration. Demand programming requires no batteries. With reprogramming and a battery, the meter becomes a full-function TOU meter with a supercapacitor for short-term carryover. The AXS4e is upgradable to an RXS4e using a software upgrade key.
This version is a full-function active, reactive and apparent energy demand-only or demand and TOU multifunction meter. Available metrics include: kW/kWh, kVAR/kVARh and kVA/kVAh, as well as power factor. kVA can be calculated from apparent power (RMS) or from arithmetric kW and kVAR.
The E650 S4e is available with an optional 32K or 128K load profile memory. Any combination of up to 15 metrics can be recorded from a list of 24 possible choices.
Available Metrics Include:
Voltage sag per phase/any phase
Voltage swell per phase/any phase
Volt-hours per phase
Amp-hours per phase
Amp-hours neutral current
Two external inputs
Demand Time of Use
Demand intervals from 1–60 minutes with up
to 15 subintervals
Up to four seasons
Supports seven different day schedules
Allows two different holiday schedules
Up to five different rates
Load profile options of 32K and 128K memory
Real-time rate entry and exit
Communication & Input/Output Capabilities
The modular E650 S4e is designed with maximum flexibility to add functionality in the future. It has the largest space in the industry for a variety of communication possibilities, such as the advanced high-speed modem, RS-232 and RS-485 boards and a variety of AMI devices that include RF, PLC and digital cellular modules.
An optional input/output board provides up to four Form C, solid-state relay outputs and up to two external inputs for recording pulses from remote sources. These relays can be programmed for end-of-interval, power factor alert, diagnostic alert, voltage alert, demand threshold alert, KYZ or load control.
