Automatic control and protection parameters of 3-phase AC motors, ”Proton-M”.
Stations of automatic control of pumping units, ”Proton-ACS.”
Taximeters automotive electronic ”Magellan-TMA1”

All kinds of devices, ”Proton - M” protect the motors from:

• poor quality mains voltage (invalid surges, phase failure, phase sequence and a violation of coalescence phase, the asymmetry of the phase voltages);

• mechanical overload (overload symmetric phase currents);

• asymmetry of the phase currents without reloading;

• disappearance of torque at the motor shaft - ”idle” speed;

• Tighten the starter motor;

• overheating of windings (winding temperature is determined by using the built-in engine temperature sensor or the temperature of the body when using the external temperature sensor).

In addition, each of the varieties of devices, ”Proton - M” provides additional protection associated with a functional use.
”Proton - Mon M” is for the protection and automatic or manual control of electric motors pump water supply and sanitation as a submersible, and console. Automatic control is carried out either by a level sensor, or by the pressure sensor.

”Proton - M Mon” can operate in water supply or vodotvedeniya (drainage).

In ”Proton - M” is automatically reset and restart the accident with exposure time.
 

”Proton - M OD” is the protection and automatic or manual control of electric drives conveyors, compressors, fans, and so on.

”Proton - M OD” has digital inputs, which can be connected to any type of discrete sensors for emergency shutdown of the motor.

”Proton - M OD” can have up to two settings of operating current, the transition between them occurs at a signal from one of the digital inputs. This allows you to organize the defense of multiwinding phase motors.
