Intelligent rectifier operates in 3-phase systems as sinusoidal mains supply and as energy recovery system.

The >pDRIVE< LX provides a constant DC supply. So it can be used in conjunction with a single drive as well as a feeding / rear feeding unit for a group drive.

Functional range:

• Mains supply function (3 AC to DC)
• Energy recovery function (DC to 3 AC)
• Prevention of low frequent current harmonics by sinusoidal mains current.
• Constant DC power supply independent from the load.
• Power factor Cos Phi approx. 1 (in both engergy directions) or compensation of reactive current with external reference.
• Short-time undervoltages can be controlled by continued operation at voltage returns by means of adjustable operating mode behaviour.
