DMPU

Motor Protection Unit DMPU

Modular installation

DMPU modularity allows to select the necessary features for

the specific application. This means minimal space

requirements for basic installations as well as huge I/O

potential.

Full variables monitoring

DMPU monitors all the electrical variables: voltages,

currents, power, power factor, voltages and current

asymmetry and the total harmonic distortion. The motor

control system is ready for plant energy management.

Variables trend storage

The device stores the trend of the selected variables and the

device status changes (as power ON/OFF, motor start and

stop, digital inputs, alarm trips, ...). DMPU also has a fast

datalogger for start-ups for fast troubleshooting.

DMPU is a modular electronic motor protection relay to control,

monitor and meter the performances of 3-phase, constant or dual

speed, AC induction motors. It is very effective for the motors

which are located in very sensitive positions in the applications

making any failure very costly. The device is able to measure the

electrical motor variables (current, voltage, harmonic distortion,

power, energy, earth leakage current, etc.), to monitor motor

overload through the thermal image, control it (i.e. start and stop,

start-delta, 2 speeds, stop it in case some critical alarm pops up,

…), and measures other variables like motor or bearings

temperature. Finally it includes data-logger functions to measure

the quality of the performances of the motor in the application.

Additional optional modules allow the collection of additional

temperature values, and input/outputs to use inside the control

logic of DMPU for a full hi-end control.
