7600 ION/7500 ION

Front Panel Display

The meters are equipped with unique, easy-to-

read 3½ x 4½ inch, (87 x 112 mm) LCD display

screens with bright back lighting and adjustable

contrast. They can display TOU, event logs,

phasors, harmonics and all instantaneous power

parameters.

A wide selection of character sizes enhance

visibility under difficult lighting conditions or at

long distances. It provides a user-friendly

interface with a screen-based menu system to

configure meter settings and an extensive

selection of pre-configured display screens, for

common applications.

Metering

Both meters offer a comprehensive set of high-

accuracy metering and recording functions.

Energy

The units are fully bi-directional and meter

energy in four quadrants. They provide active,

reactive and apparent energy parameters and can

integrate any instantaneous power parameter to

supply measurements like Volt-Hours, Amp-

Hours, etc. Energy registers can be logged

automatically on a programmed schedule.

Demand

The units support all standard demand

calculation methods, including block, sliding

window (rolling interval), thermal (exponential),

and predicted demand. They can be configured

to measure demand on any instantaneous value

and can record peak (maximum) and minimum

demand with accurate date and time stamps to

the second. Peak demand registers can be reset

manually (password protected) or logged and

reset automatically on a programmed schedule.

w kW demand, min/max

w kVAR demand, min/max

w kVA demand, min/max

w Amps demand, min/max

w Volts demand, min/max

w Demand on any instantaneous measurement

Time-Of-Use

The meters offer comprehensive time-of-use

(TOU) metering, configurable in accordance with

virtually any utility tariff structure. Automatically

record TOU register values at user-specified time

intervals, at pre-scheduled dates and times, or

when internal or external events occur. TOU

registers can be reset manually (password

protected) or on a pre-programmed schedule.

Instantaneous

Both units offer a comprehensive array of

instantaneous (real-time) measurements,

including a choice of high accuracy, 1 second or

high-speed, ½ cycle measurements, including

true RMS, per phase and total for:

w Voltage

w Current

w Active power (kW)

w Reactive power (kVAR)

w Apparent power (kVA)
