Multifunctional power measuring unit „MPR 3“
with innovative connection technology „Quick Connect“
Features / benefits
- Simple wiring of the three single-phase current-transformer-set ASKDS or our
split-core current transformers type KBR 18; KBR 32 or KBR 44 via plug
adaptor using 330 mV voltage input for equivalent primary currents
- Replaces a variety of analogue measuring devices, along with significantly
less wiring expenses
- Storage of minimum and maximum values allows monitoring and error
analysis
- Due to a digital in- and output as well as a pulse output a connection to a
power management system is possible
- Additionally this device has a Modbus-RTU interface (RS485)
Application
Energy is becoming more and more expensive and is thus a steadily growing
cost factor.
In order to detect high-level power consumers, MBS AG has developed the
multifunctional measuring unit MPR 3 (72x72 mm) and MPR 4 (96x96 mm) in
combination with the three single-phase current-transformer-set ASKDS, which
are especially designed for monitoring of 3- or 4-line networks in building
technology.
Moreover our split-core current transformers type KBR 18; KBR 32 or KBR 44
can be connected with above mentioned measuring units (MPR 3 using a plug
adaptor).
All relevant network data can be measured and displayed
Measurements
The following measurements can be displayed with the multifunctional
measuring unit MPR 3:
- The current values for voltage, current, frequency and power factor
- The real power, apparent power and reactive power for each phase and
for the whole grid
- The minimum and maximum values for voltage, current, real power, reactive
power and power factor for each phase and for the whole grid
Additionally integrated into the device is a 4-quadrant energy meter for the real
and reactive energy, two operating hours counters and a rotary field direction
display.
One of the operating hours counter can be reset manually.
The device is operated by using four buttons and the menu on the display.
All the outputs given above are galvanically isolated from the measurement
inputs and the auxiliary voltage.
