power saver

    It is applicable for wound rotor asynchronous motor reactive power local compensation. It can decrease the stator current and winding temperature rising, improving power factor and efficiency, to reduce the loss of the motor and power system.

It adopts the micro-computer and AC-AC frequency conversion technique, there is a 3 phase power supply which produced by electronic devices. The 3 phase power supply has the same frequency with motor rotor and the phase differential between the rotor and power is 90 degree. Put the power supply to the rotor loop, it will change the rotor power factor, then change the stator power factor, which can achieve the goal of reactive compensation.

1.All digital design, high precision and reliablity

2..With independent working system, when debugging or maintenance the phase advancer, needn't stop the motor

3.Automatic tracking the motor rotor, suitable for many loads, especially for constant load torque conditions.

4.Improve the power factor to 0.95, reduce reactive power by 60%

5.Reduce stator current 10%-20%, save wire loss and copper loss 20-30%

6.Many protection funstions: low voltage, rotor miss phase, communication fault, parameter fault etc.

7.With fault record function, can check the fault value, convennient for users to analyze

8.With RS485 communication interlock

9.Obvious energy saving function, users can take back the invest in half a year.
