A2000 Multifunction Panel Power Meter.
The A2000 Multifunction Programmable Panel Power Meter is powerful, four-quadrant programmable energy
meter that features a bright LED display, two freely configurable analog outputs and serial communication
ports (RS-232 and RS-485). The A2000 Multifunction Power meter can be programmed either through
software or the push buttons on the front panel.
The A2000 can be configured as a 1, 2 or 3 element device with transformer rated inputs of 5A and up to 550V.
Programmable transformer ratios allow the A2000 Power Meter to show primary values on the display and
read through the serial ports.

RS 232 and RS 485 interfaces included.
Versions available for PROFIBUS, Modbus and LON.
Minimal installation depth of less than 60 mm.
Adjustable voltage and current transformer ratios.
A single device for 1 A and 5 A current transformers.
Limit value and analog outputs included as standard equipment.
2 pulse outputs for read-out of active and reactive energy.
Data memory for continuous recording of measurement values, or for events recording
The analog outputs can be assigned to any instantaneous quantity.
Standard analog output is 20mA but this can be changed to 10Vdc with the flip of a dip-switch.
Quantities measured by the A2000 include current, voltage, active, reactive and apparent power,
power factor, line frequency and energy.
THD indication is also available for voltage and current with individual harmonics measurements
available
for the 3rd through the 15th harmonics.
Measurement of current, voltage, active, reactive and apparent power, power factor,
line frequency and energy.
Simultaneous display of up to 4 measurement values on nine digit red LED display.
Capable of communications via Profibus-DP, Lonworks interface or RS 485 interface
(depending upon
model).
Minimal installation depth, only 59.1 mm.
Load profile for storage of selected measurement values
(continuous or event triggered recording).
Two threshold limit value contacts (can be assigned as desired to measurement values).
Software for read-out and processing of measured values as they occur, or previously stored values.
