Description

Power module PM250 for Sinamics G120.

The PM250 Power Module features an absolutely unique technology which we have called “Efficient Infeed Technology”. This regenerative feedback capability of the PM260 Power Module in generating mode (electronic braking) means that energy is returned to the supply system and not destroyed in a braking resistor. This saves space in the control cabinet. The time-consuming dimensioning of the braking resistor as well as the wiring are eliminated. Generated heat is also reduced in the control cabinet.

The innovative circuit design used in Efficient Infeed Technology reduces supply harmonics. There is no need to use an optional line reactor at the supply infeed. This saves space and costs for engineering and procurement.

The PM250 Power Module is also suitable for safety-oriented applications. In conjunction with a Fail-safe Control Unit, the drive can be turned into a Safety Integrated Drive (see Control Units).

The permissible cable lengths between inverter and motor are limited. Longer cables can be used if output reactors are connected.

For frame size FSC of Power Module PM250 with an integral line filter of class A, an additional base filter of class B is available for achieving class B (see line-side power components).

The PM250 Power Modules with integrated class A line filter are suitable for connection to TN supply systems.
