2.1 Features
Area of application
This is a power monitoring device for measuring the basic electrical variables in low-voltage
power distribution. The power monitoring device is capable of single-phase, two-phase, or
three-phase measurement and can be used in three-wire, four-wire, TN, TT, and IT systems.
The power monitoring device is designed for panel mounting. It is also possible to mount it
on a DIN rail using the DIN rail support brackets available as an option.
Thanks to its large measuring voltage range, the power monitoring device can be connected
directly in any low-voltage system up to a rated voltage U
L-L
of 400 V and U
L-N
of 230 V. It can
also be employed in conjunction with voltage transformers to take measurements in
medium- or high-voltage systems.
x / 1 A or x / 5 A current transformers can be used to measure current.
The power monitoring device has a large, graphical LC display on which all measured
variables are clearly visible. The four function keys combined with the multi-language
plaintext displays make intuitive user guidance possible. The experienced operator can also
use direct navigation for quicker selection of the desired display menu.
The power monitoring device comes with a range of useful monitoring, diagnostic and
service functions, such as active and reactive energy displays and active and reactive energy
counters.
The PAC1020 can be configured via the integral RS485 interface. Measured data can be
exported for further processing.
The PAC1020 has:
•
One digital input
• One digital output
The parameters can be set either directly on the power monitoring device or via the RS485
interface using powerconfig.
Measurement
• Measurement of relevant electrical variables in an AC system
• Measurement of minimum and maximum values of all measured variables
Counters
• Energy counters measure reactive energy and active energy for import and export.
