CONTROLPRES 3PHASE

THREE-PHASE PRESSURE FLOW SWITCH WITH ADJUSTABLE WORKING PRESSURE

Three-phase power supply 400 Vac.

Starts and stops the pump depending on opening and closing of the outlets.

Allows to reduce the maximum pressure of the pump and to set the working pressure.

It has 1”1/4 male connections to guarantee a higher flow rate.

Stops the pump in case of water shortage and protects it from dry running.

Equipped with automatic restart in case of failure and anti-jamming function.

No need for an expansion tank, check valve, filter or fittings.

Can be installed on surface and submersible pumps up to 3 HP.

Maintenance free.

It differs from CONTROLPRES 3PHASE for the presence of electrical protections for the motor.

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

PROTECTION AGAINST INVERSION OF THE DIRECTION OF ROTATION OF THE MOTOR

In case of accidental inversion of a phase in power supply, the device detects 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.
