PAC3220
The PAC3220 has two identical Ethernet interfaces with integral switch. These can be used
to connect other Ethernet nodes to the network.
Two identical expansion module interfaces allow the connection of a further two optionally
available expansion modules. Expansion modules can be used to connect the power
monitoring device to another bus system or to expand its range of functions.
The PAC3220 features:
● Two digital inputs
● Two digital outputs
An optional expansion module can be installed to increase the available number of inputs
and outputs.
The parameters can be set either directly on the power monitoring device or via the
communication interface.
Measurement
● Measurement of all relevant electrical variables in an AC system
● Measurement of minimum and maximum values of all measured variables
● Averaging of all measured values directly on the device in two stages, which ar
e
i
ndependent of each other and freely configurable (aggregation)
Counters and power demand
● A number of energy counters capture active energy, reactive energy, apparent energy for
off-peak and on-peak, import and export.
● Calculation and storage of the average value for active power and reactive power fr
om
t
he last demand period to allow simple generation of load profiles using software.
Programmable demand period from 1 to 60 mins.
● Daily energy counter for active energy for each day of the preceding two months.
● Monthly energy counter for active energy for each month of the preceding two years.
● Configurable universal counter for counting limit violations and status changes at t
he
di
gital input or output, or for indicating the active energy or reactive energy of
a
c
onnected pulse encoder.
● Operating hours counter for monitoring the runtime of a connected load.
Display and operator control
● LC display
● Four control keys with variable function assignment
● LED with variable function assignment
