Features of the versions

LOGICPRESS 3PHASE PLUS
LOGICPRESS 3PHASE PLUS

It differs from the LOGICPRESS 3PHASE due to the presence of electrical protections for the motor.

It can be powered with either 230 or 400V three-phase voltage.

PROTECTION AGAINST INVERSION OF THE DIRECTION OF ROTATION OF THE MOTOR

In the event of accidental inversion of a power phase, the appliance recognizes the anomaly and automatically maintains the correct

direction of rotation of the motor as set and verified during installation.

PROTECTION AGAINST A MISSING PHASE IN POWER SUPPLY

In the event of a missing phase in power supply, the device detects the fault and prevents the pump from starting.
