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.

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
harmonic measurements available for the 3rd through the 15th
harmonics.

FEATURES |
- 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.
