Siemens SINAMICS G120 6SL32250BH311AA1 PM260 3-Phase Internal Air Cooling Power Module With Class A Integrated Line Filter

PM260 power modules have been designed for applications from 500 to 690 V. They are capable of energy recovery and include a sine wave filter to reduce the stress on the motor and for long cable lengths. The PM260 power module features an absolutely unique technology efficient infeed technology. This feature provides the ability to feed energy back into the supply system in the generator mode (electronic braking) so that the energy is not wasted in a braking resistor. This saves space in the control cabinet. The time consuming process of dimensioning the braking resistor and the expense of the extra wiring are eliminated. Furthermore, heat losses in the control cabinet are reduced. The innovative circuit design used in efficient infeed technology reduces the line harmonics. There is no need to use an optional line reactor at the supply infeed. This saves space and cost for engineering and procurement. The PM260 power modules are also characterized by a higher rated pulse frequency combine with a high efficiency and an integrated sine wave filter. The integrated sine wave filter ensures that the inverter output current is sinusoidal and supports cable lengths of up to 200 m (656 ft) shielded and 300 m (984 ft) unshielded. An output reactor is therefore not required. Furthermore, lower bearing current flow and there is a lower voltage stress that reduces the overall stress on the motor. The use of SiC free wheeling diode an absolutely unique innovation makes the PM260 power module extremely compact. It is also highly resistant to thermal loading and operates very quietly as a result of the high clock frequencies. Standard motors can be used in conjunction with the PM260 power module. The winding system insulation strength does not have to be increased. The PM260 power module is suitable for safety-oriented applications. In conjunction with a fail safe control unit, the drive can be transformed into a safety integrated drive (see control units). The PM260 power modules with integrated line filter class A are suitable for connection to TN supply systems. Power modules without integrated line filter can be connected to grounded TN/TT systems and non-grounded IT systems.
